00:00:00New iPhone models with large screens have a convenient option called reachability.

00:00:05Thanks to this function, you don't have to struggle to reach the top of the screen.

00:00:09This feature can be found in the phone's accessibility settings.

00:00:13It allows you to lower your screen down.

00:00:15The rumble strips on the side of the road are there to wake up sleepy drivers who doze off behind

00:00:20the wheel.

00:00:21When your tires drift off onto these strips, the noise and vibration work like an alarm clock.

00:00:27Most kitchen shears have metal, plier-like teeth in the middle.

00:00:30They allow you to use the device for multiple purposes.

00:00:33They're placed between the handle grips for you to crack nuts, crab shells, and whatnot.

00:00:38You can also open jars and bottles with their help.

00:00:41Some people even use these teeth to remove stems from herbs.

00:00:45If your audio jack has three rings, it means your device can produce stereo sound, and your earphones have the

00:00:51microphone function.

00:00:52The black grating on a microwave oven door is called a Faraday shield.

00:00:57It stops microwaves from getting away.

00:00:59If they do, your food won't cook properly.

00:01:02The digits on an egg can tell you a lot about the product.

00:01:06In many countries, there's a special labeling system.

00:01:09The first number indicates the method of production.

00:01:11The following two-letter code stands for the country where the egg was produced.

00:01:15And then you can find a registration number.

00:01:17It indicates the laying hen establishment.

00:01:20The first number in this code can vary from 0 to 3.

00:01:240 means it's an organic egg.

00:01:261. It's a free-range egg, which means it was produced by a hen that was allowed to wander around

00:01:31outdoors.

00:01:322 stands for an egg produced in a deep-litter indoor housing.

00:01:363. You're about to buy a cage farming egg.

00:01:39A black band that runs along the edges of your windshield is called the FRIT.

00:01:444. It's a baked-in ceramic paint that starts as solid black bands near the edge of the windshield.

00:01:49Then it dissolves into smaller dots.

00:01:52The FRIT makes the glass rougher, and the adhesive sticks to it better.

00:01:56The FRIT protects the urethane sealant.

00:01:58It's the substance that fixes the glass to the frame.

00:02:01It also prevents the sun's ultraviolet rays from melting the adhesive.

00:02:05As for the black dots, they help distribute the temperature in the car more evenly.

00:02:09They're aesthetically pleasing, too.

00:02:11Without them, the contrast between the glass and the dark band would be too obvious.

00:02:17If you see a pair of jeans with an extra loop, those are special jeans for cyclists.

00:02:22They're likely to belong to the commuter clothing line, and the loop's main purpose is to hold your bike lock.

00:02:29Many zipper sliders have outer rings, especially if such sliders are supposed to be used together.

00:02:35These rings are added so that you can connect the sliders with a lock and keep pickpockets away.

00:02:41Keyboards come with little legs.

00:02:43They were designed for you to be able to tilt your keyboard.

00:02:46This way, you can actually see which keys you're hitting.

00:02:49At the same time, a flat keyboard doesn't make your wrists so tired,

00:02:52and people who can type without looking at the keyboard don't need those legs whatsoever.

00:02:57An olive spoon is usually made of stainless steel and has a small hole cut in its bowl-shaped head.

00:03:04The main purpose of this utensil is to lift olives, cherries, pickled garlic, and other products from liquid-filled jars,

00:03:11cans, or bowls.

00:03:11The hole in the middle allows you to drain the liquid gathering in the spoon fast and easily.

00:03:17What'll they think of next?

00:03:19Doughnuts are shaped like rings because, otherwise, they get overdone at the edges and remain uncooked and gooey inside.

00:03:26Make a hole in the center, and both the outsides and the insides will be cooked at the same time.

00:03:31Round-shaped doughnuts with no holes are usually filled with custard, cream, or jelly.

00:03:36Mmm.

00:03:38Such doughnuts don't have any corners, which means there are fewer weak spots for the filling to spurt out from.

00:03:44If you grab a full juice box a bit too firmly, you can get sticky liquid all over the place.

00:03:49To avoid such situations, flip up the tabs on the sides of the juice box.

00:03:54You can use them to hold your drink.

00:03:56Some cars have a tiny coffee cup sign on the dashboard.

00:04:00It's the vehicle's anti-drowsiness mechanism.

00:04:02Some manufacturers equip their cars with a drowsiness detection system.

00:04:06It analyzes the speed, wheel angle, and lane deviations, and figures out if it's time for the driver to take

00:04:13a break.

00:04:14If it is, the vehicle makes several audio signals, and the coffee cup sign starts to flash.

00:04:20Produce stickers on fruit and veggies you get at the supermarket are full of information.

00:04:25If there's a four-digit code on the sticker, the product was grown conventionally.

00:04:29In most cases, it also means that pesticides were used in the process.

00:04:33If the product is organic, its sticker has five digits, and the first one is nine.

00:04:39Genetically modified products also have a five-digit code, but the first number is eight.

00:04:45Sugar used to be sold in sugar loaves.

00:04:47Those were tall, hard cones.

00:04:50At those times, to get sugar ready for tea, people had to use special hammers to break a loaf apart

00:04:56first.

00:04:56After that, they cut the sugar into smaller and more nicely shaped lumps.

00:05:01Only in the middle of the 19th century, people invented the first press that cut sugar into cubes.

00:05:07This way, the product was easier to store and transport.

00:05:10A little hole in the end of your wrench can provide your screwdriver with some extra torque.

00:05:15Just slide the end with the hole over the screwdriver.

00:05:18You can also use this method when the angle is awkward.

00:05:21While driving, when it's already dark, you might get blinded by the headlights of the car moving behind yours.

00:05:27If you have a manual rearview mirror, find a tab at the bottom and flip it.

00:05:32The mirror has a reflective material behind its glass.

00:05:35By flipping the tab, you change the angle of this material, dimming the lights in the mirror.

00:05:40Most ice cream scoopers come in different colors.

00:05:43It has nothing to do with aesthetics.

00:05:46The color indicates the size of the scoop.

00:05:48This way, you can easily figure out how many scoops you'll need to fill 32 ounces.

00:05:53Wow, a 32-ounce sundae!

00:05:55Sign me up!

00:05:56Some caps on small tubes are hollow on top and have a little spike inside.

00:06:01Its purpose is to break the foil sticker sealing the tube.

00:06:04The neck fits right in this hole, and the spike is designed to break the seal.

00:06:09This way, you don't need to tear the tiny foil seal off with your fingers.

00:06:13The letter R in a circle on the product's packaging means that the trademark is officially registered.

00:06:19Once it's done, the trademark's owner has the right to place this letter on all their products.

00:06:25They can also sue anyone who tries to use their trademark.

00:06:28A gas pump usually has a small metal latch or hook on its handle.

00:06:33That's a trigger lock.

00:06:34You can use it to lock the handle in the open position.

00:06:37Then the gas will keep pumping even if you walk away.

00:06:41Coins used to be shaped randomly or have no shape whatsoever in the past.

00:06:45Dishonest people used it to their advantage.

00:06:48They stole valuable metals the coins were made of by chipping their corners off.

00:06:52It was illegal, and to prevent this kind of fraud, round coins were invented.

00:06:57After that, it became easy to instantly notice when a coin had been fiddled with.

00:07:02Those two holes in a lollipop stick are there to hold the candy in place.

00:07:07When the stick is dipped in hot liquid syrup, it flows into the holes and solidifies.

00:07:11Now, your suite is there to stay.

00:07:14Fabric squares that come with clothes are for you to try out your cleaning products on them first.

00:07:19This way, you won't ruin the entire item once you decide to wash it.

00:07:23The holes in the bottoms of earphones allow air to circulate up and through the speakers.

00:07:28It helps to increase low frequencies, making the bass sound deeper.

00:07:33The sound quality also becomes much better.

00:07:35Don't I sound better?

00:07:37You can adjust your stapler so that it staples documents together only temporarily.

00:07:42It's done by rotating the crimp area.

00:07:45Most staplers have two options for stapling.

00:07:47One is standard, but the other side bends staples away from the center.

00:07:52Later, when you don't need them anymore, you can easily remove them by hand.

00:07:56If you store peanut butter jars upside down, the oil will move to the bottom and all the solids will

00:08:02be on top.

00:08:32Hey, don't laugh.

00:08:33But the scale is much smaller, and these strands aren't actually woven together.

00:08:37What ridges do is remove the support of the surrounding polymer fibers.

00:08:42When the edge is flat, the molecules are surrounded and kind of protected by their mates.

00:08:47But if the edge is uneven, molecules on the peaks of the ridges are much more exposed to mechanical damage.

00:08:54Plus, such an uneven edge allows you to apply more force to a specific point, the groove.

00:09:00And once that point fails, the groove moves to the next point, causing more tearing.

00:09:06And this process continues until you stop applying the force or until you're done tearing the packaging apart.

00:09:13But this isn't the only packaging secret.

00:09:15I'm about to reveal the most unexpected packaging facts.

00:09:19Now, is this what the future of packaging looks like?

00:09:23A Swiss company has invented a magic juice box.

00:09:26It's made of agar-agar seaweed gel and water.

00:09:29It can only contain short-term smoothies and juices.

00:09:33The box also withers at the same rate you consume the product inside.

00:09:38Wow, doesn't it sound like the future is here?

00:09:40That overwhelming smell of coffee that literally hits you once you open a jar with instant coffee?

00:09:47This scent is actually just a coffee aroma sprayed onto the lid.

00:09:51It's done to provide you with the enticing smell of freshly ground coffee.

00:09:55One of Korea's leading manufacturers of instant noodles has come up with innovative packaging for their production.

00:10:02It can be safely used in microwaves.

00:10:05The company claims that some additional material used in this packaging can remain intact without melting, even at high temperatures.

00:10:13Well, it'll definitely make the process of heating up your lunch much faster.

00:10:17Now, almost all food we consume has an expiration date.

00:10:22But this rule doesn't apply to water.

00:10:25Hmm.

00:10:26But how come there's an expiration date on every water bottle?

00:10:29There's no paradox here.

00:10:31This expiration date refers to the bottle, not the water inside.

00:10:36They say that regardless of the brand, all chips have a best before date that ends on a Saturday.

00:10:43It's because a production week starts on a Sunday and correspondingly ends on a Saturday.

00:10:49Well, I've checked my stash and it seems to be true.

00:10:52Go look at yours and write in the comments what you found out.

00:10:56Bubble wrap was originally designed to serve as textured wallpaper.

00:11:00It was invented in 1957 by engineers Mark Chavons and Alfred Fielding in New Jersey.

00:11:07They sealed together two shower curtains trapping inside a smattering of air bubbles

00:11:12and wanted to sell the resulting product as an innovative kind of wallpaper.

00:11:17Unfortunately, the product turned out to be a failure as wallpaper.

00:11:21Then the inventor started selling it as greenhouse insulation.

00:11:24But it wasn't until 1961 that the material's protective qualities were discovered.

00:11:31And the first client that used bubble wrap as a packaging material was IBM.

00:11:36This company used it to protect its big IBM 1401 mainframe computer during shipment.

00:11:43Now, people love personalized products.

00:11:46According to researchers, a whopping 52% of online customers are more willing to repeat their purchases

00:11:52from a company when they get personalized shipping boxes.

00:11:56If you've ever seen someone unboxing Apple products,

00:11:59you probably noticed that the company used very laconic packaging.

00:12:03This probably made you think that they put no effort into it.

00:12:07But that's not true.

00:12:08To achieve such a level of perfect simplicity,

00:12:11Apple has created a real culture around its packaging.

00:12:15The company's headquarters even have a special place

00:12:17where they come up with packaging designs for new products.

00:12:21The egg carton was designed in 1911 by newspaper editor Joseph Coyle from British Columbia.

00:12:28The main goal of this invention was to resolve a dispute

00:12:31between a local farmer and a hotel owner

00:12:34who kept complaining that the farmer's eggs were delivered broken.

00:12:38So, necessity is the mother of invention.

00:12:42Nike has created a shoebox made completely out of recycled trash materials,

00:12:47mainly drink containers.

00:12:49This box also allows its owner to wear it as a backpack.

00:12:54Now, paper packaging for food goes all the way back to China,

00:12:57to the 2nd century BCE.

00:13:00At that time, food was often wrapped in thin sheets of mulberry bark.

00:13:04And later, the idea spread all over the world.

00:13:08And in 1879, one accident literally changed history.

00:13:12A worker from a paper bag factory in Brooklyn set the machine he used to the wrong settings.

00:13:19And instead of creasing small bags, it cut through them.

00:13:22When the owner of the factory readjusted the settings on the machine,

00:13:26he realized that it could cut and crease at the same time.

00:13:30This led to the appearance of mass-produced paperboard boxes.

00:13:34Now, researchers have found out that the process used during the manufacturing of cardboard boxes

00:13:39can ward off germs.

00:13:41Hear me out.

00:13:42To make cardboard, they shape layers of paper and bond them at a temperature of up to 200 degrees Fahrenheit.

00:13:49That's hotter than most harmful bacteria can withstand.

00:13:52That's why cardboard boxes are a rather safe way to package foods.

00:13:57After all, they come out of the manufacturing process sanitized,

00:14:01even when they're made of recycled materials.

00:14:04That little open jar icon on cosmetic packaging is the PAO, period after opening symbol.

00:14:11It informs consumers about the period of time a product may be used after the package is unsealed.

00:14:17The symbol, featuring a number followed by the letter M for months,

00:14:22can be seen on almost all cosmetic products.

00:14:25Some plastic milk containers have dents on their sides.

00:14:29These dents serve several purposes.

00:14:31For one thing, when the milk spoils,

00:14:33this process usually causes swelling and high-pressure buildup inside the container.

00:14:39That's when the dent comes in handy.

00:14:41It pops out and doesn't let the jug blow up.

00:14:43Plus, if you decide to freeze the milk, it will expand like any other liquid.

00:14:48And then again, the indentation will pop out

00:14:52and prevent the container from breaking inside your freezer.

00:14:55Soda bottles are always filled in such a way

00:14:58that there's some space between the liquid and the cap.

00:15:02That's because soda contains carbon dioxide.

00:15:05It's a gas that can expand once the bottle is heated.

00:15:08If there's no gap in the bottle,

00:15:10it can break because of the pressure building inside.

00:15:13Also, when you open your drink,

00:15:15the gases go out in the form of bubbles,

00:15:17and the drink is likely to overflow.

00:15:20The gap helps with this problem, too.

00:15:23Now, about those horizontal lines on plastic bottles.

00:15:26They help hold bottles up.

00:15:29Some bottles are produced from soft plastic.

00:15:31Without the lines, they wouldn't keep their shape.

00:15:34Instead, they would twist easily or even break.

00:15:38Number 57 on a Heinz ketchup bottle

00:15:40has nothing to do with the product label.

00:15:43The truth is that the place with the numbers

00:15:46is the very sweet spot you should tap to get the ketchup flowing.

00:15:49So, stop smacking the bottom of your sauce bottle

00:15:52and tap the 57.

00:15:54By the way, if you've been wondering

00:15:56why the number is exactly 57,

00:15:59not 34 or 89,

00:16:01this comes from the historical advertising slogan

00:16:0457 Variety,

00:16:06created by the Heinz Company,

00:16:08located in Pittsburgh, USA.

00:16:09This advertising campaign told customers

00:16:12about the numerous products manufactured by the company.

00:16:16Now, at first sight,

00:16:18everything is obvious about plastic lids on disposable cups.

00:16:21To keep your beverage inside, right?

00:16:23But that's not all they're capable of.

00:16:26As soon as you find a cozy spot

00:16:28and get ready to sip on your drink,

00:16:30you can use the lid as a coaster.

00:16:33If you look carefully,

00:16:34you'll notice special ridges

00:16:36that hug the bottom of your cup snugly.

00:16:38It's a snuggly hug.

00:16:40The size of each lid

00:16:41fits the bottom of the corresponding cup.

00:16:46And the soft round part

00:16:48under a soda bottle cap

00:16:49keeps the carbonation from escaping.

00:16:52Without it,

00:16:53your pop would go flat in no time,

00:16:55probably even before you buy it.

00:17:01Road and construction workers

00:17:03are usually dressed in orange

00:17:04because the bright orange hue

00:17:06is visible even in bad weather.

00:17:08It's the most effective color

00:17:10to attract attention and alert people.

00:17:12No wonder lots of safety jackets

00:17:13and traffic cones are orange as well.

00:17:16The stop sign has an eight-sided shape

00:17:18to help drivers recognize it easily,

00:17:20even if they see it from the back.

00:17:22And when the signs weren't reflective yet,

00:17:24the octagon shape

00:17:25prevented drivers from confusing the stop sign

00:17:28with any other at night.

00:17:30The rumble strips on the side of the road

00:17:32are placed there to alert drivers

00:17:34who doze off behind the wheel.

00:17:36When their tires move over these strips,

00:17:38the noise and vibration

00:17:39work like an alarm clock.

00:17:41There are magnetic locks

00:17:42on fuel hoses at gas stations.

00:17:44They come in handy

00:17:46if someone drives away

00:17:47with the gas nozzle

00:17:48still attached to their car.

00:17:49In this case,

00:17:50the lock detaches the hose automatically.

00:17:53Oh, that's embarrassing.

00:17:55Gasoline looks like a rainbow in a puddle

00:17:57because it can't mix with water.

00:17:58It forms a thin membrane over it.

00:18:01When light reflects from it

00:18:02and the water at the same time,

00:18:04you've got a rainbow.

00:18:06A triple handle on a jerry can

00:18:09is there to make it easier

00:18:10for two people to carry it

00:18:11and distribute fuel evenly.

00:18:13Gas cans often have a second hole

00:18:15that actually needs to be uncapped too

00:18:17before you pour the gas.

00:18:19The air passage will prevent it from pouring out,

00:18:22so no more fuel waste.

00:18:24Most gas cans have two holes with caps,

00:18:27a bigger and a smaller one.

00:18:28You're supposed to uncap the smaller hole

00:18:30before pouring gas inside the bigger one.

00:18:33It'll prevent the liquid from glugging

00:18:35and spilling all over your clothes

00:18:37and the ground.

00:18:38Another little thingy we often neglect

00:18:40is a point on an ointment cap.

00:18:43Most tubes are usually sealed

00:18:44with a plastic film or a foil,

00:18:46and opening it with your fingernails

00:18:48isn't the best idea.

00:18:49A point easily opens

00:18:51even the most safely sealed tube.

00:18:53You can use most screwdrivers together

00:18:56with a wrench to create more torque.

00:18:59Just place the wrench

00:19:00over the handle of the screwdriver.

00:19:02This way, you'll need to apply

00:19:04a lot less force than before.

00:19:05You'll also be able to get

00:19:07to hard-to-reach areas more easily.

00:19:10They install cameras in shops,

00:19:12banks, and hospitals

00:19:13to monitor everything.

00:19:14If something happens,

00:19:16you can call the police or rescuers.

00:19:18The camera really helps

00:19:20to solve a lot of problems.

00:19:21Why are there no cameras on planes?

00:19:24The crew keep order on the plane,

00:19:26but they won't be able to do anything

00:19:28if something serious happens.

00:19:30Besides, there's nowhere to run

00:19:32on the plane.

00:19:33During the flight,

00:19:34the cameras are useless,

00:19:35and after the flight,

00:19:37the words of the passengers

00:19:38work ideally instead of cameras.

00:19:40So, if cameras do no good,

00:19:42then why spend money on them?

00:19:44Water is great at cleaning stuff

00:19:46because it has triangular molecules.

00:19:48They're made of one oxygen

00:19:50and two hydrogen atoms.

00:19:51Um, H2O?

00:19:53Such molecules have slightly different charges

00:19:55on their opposite sides,

00:19:57pretty much like magnets.

00:19:58That's why water easily sticks

00:20:00to other molecules,

00:20:01including those that make up dirt.

00:20:03Lots of private houses

00:20:05have triangular-shaped roofs

00:20:06because this allows rain,

00:20:08snow,

00:20:08and fallen leaves

00:20:09to slide off the slope.

00:20:11If all this stuff

00:20:12piled up on top of your house,

00:20:14one day,

00:20:15your roof would collapse.

00:20:16When a storm is coming,

00:20:18clouds seem to turn dark,

00:20:20but it's just an illusion.

00:20:21Thin clouds on a sunny day

00:20:23let the light through easily.

00:20:25They also scatter

00:20:26all the colors

00:20:26of the light spectrum.

00:20:28This makes us perceive

00:20:29the clouds as white,

00:20:30but the thicker the clouds are

00:20:32and the more water droplets

00:20:33they contain,

00:20:34the less light they let through

00:20:36and the darker they look.

00:20:38A good doorknob

00:20:39is the one made of brass,

00:20:41bronze,

00:20:41or some copper alloys.

00:20:43These metals

00:20:44have an anti-germ effect.

00:20:46Bacteria spread

00:20:47way slower on them.

00:20:49They also get rid of germs

00:20:51pretty fast,

00:20:51within a couple of hours.

00:20:53Nope,

00:20:53it doesn't mean

00:20:54you don't have to wash your hands.

00:20:57Diamonds have such

00:20:58symmetrical shape

00:20:58to show you their brilliance.

00:21:00Initially,

00:21:01the gems

00:21:01aren't so beautiful.

00:21:02They go through

00:21:03several stages of cutting

00:21:05and then

00:21:05become pieces of elegance.

00:21:08Most of these stones

00:21:09have a round shape

00:21:10with slightly pointed corners.

00:21:12Diamonds shine the brightest

00:21:13in this shape.

00:21:15Why are there two holes

00:21:17in the socket?

00:21:18The left hole

00:21:18is neutral,

00:21:19the right hole

00:21:20is not,

00:21:21and the gap underneath

00:21:22is ground.

00:21:24Electricity needs to flow

00:21:25through the chain.

00:21:26The current flows

00:21:27from the hot slot,

00:21:29passes through your phone charger,

00:21:30for example,

00:21:31and then goes through

00:21:32the neutral hole.

00:21:34Ever wondered

00:21:34what that small pocket

00:21:35on your jeans is for?

00:21:37People used to wear

00:21:38watches on chains.

00:21:39That small pocket

00:21:40was meant for it.

00:21:41Now,

00:21:42almost no one

00:21:43wears such a watch,

00:21:44but the pocket remains.

00:21:45You can still keep

00:21:46something small in there

00:21:47like a ring.

00:21:49In London,

00:21:50there are some poles

00:21:51that look like street lamps,

00:21:52but there are no bulbs.

00:21:53Well,

00:21:55their official name

00:21:55is stink pipes,

00:21:57and they're a thing

00:21:58of the past now,

00:21:59but they used to come

00:22:00in handy back

00:22:00in the 19th century.

00:22:02These hollow poles

00:22:03would vent away the air

00:22:04and explosive gases

00:22:05with bad smells

00:22:06to prevent,

00:22:07shall we say,

00:22:08unwanted consequences.

00:22:11Most kitchen shears

00:22:12have metal

00:22:12plier-like teeth

00:22:13in the middle.

00:22:14Between the handle grips,

00:22:16they can help you

00:22:16crack nuts,

00:22:17crab shells,

00:22:18and other tough products.

00:22:19You can also open

00:22:21jars and bottles

00:22:22or remove herb stems

00:22:23with their help.

00:22:25Leather often looks dull

00:22:27to the eye

00:22:27because it's covered

00:22:28with itsy-bitsy scratches

00:22:29and scrapes.

00:22:30They scatter the light

00:22:32that hits the material.

00:22:33When you coat your shoes

00:22:34in a layer of wax,

00:22:35you fill these tiny crevices.

00:22:37The surface becomes smoother

00:22:39and the rays of light

00:22:40bounce off it more evenly.

00:22:42That's why the leather

00:22:43looks shiny.

00:22:45Highlighters are filled

00:22:46with a special

00:22:47semi-transparent fluorescent ink

00:22:49that can glow in dim light.

00:22:51Yellow and light green hues

00:22:53are the most popular

00:22:54because they don't prevent you

00:22:56from seeing the text

00:22:57after black and white

00:22:58photocopying.

00:22:59Photocopiers perceive

00:23:00yellow and light green marks

00:23:02as very pale

00:23:03and don't print them.

00:23:04They make magnets

00:23:06shaped as a horseshoe

00:23:07because this increases

00:23:08the magnetic force.

00:23:10Colors matter too.

00:23:11The blue part

00:23:12indicates the south pole,

00:23:13the red part

00:23:14the north pole.

00:23:15The two poles

00:23:16work simultaneously

00:23:17and increase the attraction force.

00:23:20The dime-sized holes

00:23:22in elevator doors

00:23:23is actually a keyhole.

00:23:25If the doors get stuck,

00:23:26an operator can open them manually

00:23:28thanks to this hole.

00:23:29They'll just insert

00:23:30a special key.

00:23:32The tiny hole

00:23:33in the airplane window

00:23:34is there to balance air pressure.

00:23:36The window

00:23:37has three layers.

00:23:39The outer pane

00:23:40is extremely sturdy.

00:23:41It can withstand

00:23:42air pressure differences

00:23:44during takeoff

00:23:44and landing.

00:23:45The inner pane,

00:23:46which is the closest to you,

00:23:48is made of cheaper materials.

00:23:49It prevents potential damage

00:23:51to the window.

00:23:52The hole itself

00:23:53is in the middle pane.

00:23:55It not only balances

00:23:56the pressure

00:23:57but also prevents

00:23:58the window from fogging.

00:24:00Escalator brushes

00:24:01are there for your safety.

00:24:03They don't allow you

00:24:04to come too close

00:24:04to the edge

00:24:05of the escalator.

00:24:06This way,

00:24:07your clothes won't end up

00:24:08between the steps.

00:24:10You see the sun

00:24:11as yellow or orange.

00:24:12Because the atmosphere

00:24:14of our planet

00:24:14scatters such colors

00:24:15as blue,

00:24:16green,

00:24:17and violet.

00:24:18This is also why

00:24:19the sun looks warmer

00:24:20at sunrise and sunset.

00:24:22Go shopping

00:24:23for some oranges

00:24:24and I'm sure you'll get them

00:24:25in a red mesh bag.

00:24:27You'll rarely see them

00:24:28lying around

00:24:28without one of those.

00:24:30It's pure marketing

00:24:31and that color

00:24:31isn't a random choice.

00:24:33When packed

00:24:34in a red mesh bag,

00:24:35oranges appear

00:24:36more orange,

00:24:37fresher,

00:24:38and more appealing to you.

00:24:39So,

00:24:40you're more likely

00:24:41to buy them, right?

00:24:42Lemons are usually sold

00:24:44in green mesh bags

00:24:45for a similar reason.

00:24:46If you pack them in red,

00:24:48they'll appear more orange.

00:24:49Green goes better

00:24:50with yellow

00:24:51and makes those lemons

00:24:52stand out.

00:24:54Mattress manufacturers

00:24:55make a limited number

00:24:56of different mattresses

00:24:58and the only way

00:24:58to make them look different

00:24:59is to come up

00:25:00with a fancy stitching pattern.

00:25:02Two mattresses

00:25:03of two different companies

00:25:04might be the exact same quality

00:25:06but cost differently.

00:25:08Most people will never know it

00:25:09and will decide

00:25:10that different patterns

00:25:11need something

00:25:12in terms of quality.

00:25:13So,

00:25:14when shopping,

00:25:15don't mind the pattern at all.

00:25:17Almost all hotels

00:25:19have white bed sheets.

00:25:20They choose this color

00:25:21specifically to show

00:25:22how high their standards

00:25:23of cleanliness are.

00:25:24The whiter

00:25:25and brighter the sheets are,

00:25:27the more luxurious

00:25:28the hotel seems.

00:25:29It's much easier

00:25:30to see dirt

00:25:31and stains

00:25:31on white linen.

00:25:32It's like proof

00:25:33that you've checked

00:25:34into a clean room.

00:25:37So get this,

00:25:38an extra hole

00:25:39at the upper part

00:25:40of the sink

00:25:40has multiple hidden functions.

00:25:42First,

00:25:43in case someone forgets

00:25:44to close the tap,

00:25:45the water won't overflow

00:25:46and the bathroom

00:25:46won't get flooded.

00:25:48Second,

00:25:48thanks to that hole,

00:25:50the water drains faster

00:25:51and it gives an escape

00:25:52for the air,

00:25:52helping the water flow down.

00:25:56Those two holes

00:25:56on a side

00:25:57of any Converse shoe

00:25:58are not only

00:25:59to let the stinky air out.

00:26:01Sure,

00:26:01breathability

00:26:02is important

00:26:02for any athlete.

00:26:03The second reason

00:26:04is that athletes

00:26:05lace through those holes

00:26:06to get a better grip.

00:26:10Donuts have a hole

00:26:11in the middle

00:26:11and it doesn't stand

00:26:12for O in donut.

00:26:14It's not designed

00:26:15for an easier grip either,

00:26:16though it can be

00:26:17quite convenient.

00:26:18It's actually made

00:26:19this way for mass baking

00:26:20so that they can cook

00:26:21all the way through evenly.

00:26:25Baby carrots are tiny

00:26:26and,

00:26:27unlike regular carrots,

00:26:28wet.

00:26:29Baby carrots

00:26:30aren't some special

00:26:31sort of carrots.

00:26:31They're actually made

00:26:32of regular carrots

00:26:33by cutting off the skin

00:26:34and outer layers

00:26:35and then polishing them

00:26:37to look that pretty.

00:26:38The problem

00:26:39is that they can't

00:26:40retain moisture.

00:26:41A regular carrot

00:26:42retains some water inside

00:26:43because of the layers

00:26:44that locks it in.

00:26:45Once they're chopped out,

00:26:46baby carrots

00:26:47can dry out easily,

00:26:48so they usually sell them

00:26:49in bags

00:26:50with some water inside.

00:26:52Toy stores

00:26:53are filled

00:26:54with Beanie Baby

00:26:55plush toys

00:26:55and a detail

00:26:56that is even more iconic

00:26:58than their huge eyes

00:26:59is their tags

00:27:00saying T-Y.

00:27:02That's a small

00:27:02manufacturing company

00:27:03not so many people

00:27:04have heard of.

00:27:05Beanie Babies

00:27:06appeared in 1993

00:27:07and they went

00:27:08insanely popular.

00:27:10T-Y is the name

00:27:11of the company

00:27:11but it's not

00:27:12an abbreviation.

00:27:13It's the actual name

00:27:14of the company's founder,

00:27:16H. Ty Warner.

00:27:19Most metallic zippers

00:27:20have a hidden lock

00:27:21inside them

00:27:22to save you

00:27:22from awkward situations

00:27:23such as an undone fly.

00:27:26Oh boy.

00:27:27Don't leave the zipper handle

00:27:28in an upward position.

00:27:29When you pull it downwards,

00:27:31it automatically locks.

00:27:32It's all thanks

00:27:33to those tiny grooves

00:27:34hidden underneath the handle.

00:27:38Almost any public toilet

00:27:40has a large gap

00:27:41between the floor

00:27:41and the door.

00:27:42The reason for such

00:27:44a zero privacy thing

00:27:45is to actually minimize

00:27:46the level of privacy

00:27:47and comfort

00:27:48so that people

00:27:49wouldn't stay there long

00:27:50and there'd be no lines.

00:27:51It's also easier to clean

00:27:53and safer

00:27:54if some emergency occurs.

00:27:58Headrests in a car

00:27:59are about comfort

00:28:00and detachable headrests

00:28:02are about safety.

00:28:03If you pull the headrest

00:28:04out of a seat,

00:28:05you'll see two bars

00:28:06which are quite sturdy.

00:28:08If you ever get locked

00:28:09or trapped in a car,

00:28:10you can get out of there

00:28:11smashing the window

00:28:12with these bars.

00:28:17Many cups and mugs

00:28:18have little grooves

00:28:19on the bottom

00:28:20on purpose.

00:28:20They're designed

00:28:21for dishwashing machines.

00:28:22The grooves

00:28:23let the water flow

00:28:24and not spill over your feet

00:28:25when you take the cup out.

00:28:27Also,

00:28:28those grooves

00:28:29let the air flow

00:28:30so the cup doesn't crack

00:28:31even if the tea

00:28:32is scalding.

00:28:35Almost all measuring tapes

00:28:36have a metal tip

00:28:37with a small slot

00:28:38on the end.

00:28:39You can use this slot

00:28:41to hang the tape

00:28:41on a nail or a screw

00:28:42to make measurements

00:28:43without anyone's help.

00:28:46Sometimes,

00:28:47this tip has a row

00:28:48of sharp points

00:28:48along the edge

00:28:49on one side.

00:28:50That comes in handy

00:28:51when you want to leave a mark

00:28:52without using a pencil.

00:28:55Doorknobs are usually

00:28:56made of brass,

00:28:57bronze,

00:28:58and some other copper alloys

00:28:59for a reason.

00:29:00They have an antibacterial effect

00:29:02so they stop microbes

00:29:04from spreading.

00:29:05They get rid of a range

00:29:07of harmful germs

00:29:07pretty fast

00:29:08within a couple of hours.

00:29:10But don't forget

00:29:10to wash your hands

00:29:11anyway.

00:29:14Grocery carts

00:29:14have loops

00:29:15for a reason.

00:29:16You don't want

00:29:17to put your jacket

00:29:18in a cart

00:29:18next to potatoes

00:29:19and onions.

00:29:20Hang it on a loop.

00:29:22This little hook-like thing

00:29:23is there to help you

00:29:24better organize

00:29:24the space in your cart.

00:29:26The carts

00:29:27also have

00:29:28a super handy grid.

00:29:29Whenever the cart's full,

00:29:31you just need

00:29:31to lift the grid

00:29:32and attach the shopping basket

00:29:33for extra purchases.

00:29:35Placing it in between

00:29:36the horizontal bar

00:29:37above the wheels

00:29:38and the hooks

00:29:38the grid has.

00:29:41A point in an ointment cap

00:29:43is there for a reason too.

00:29:45Most tubes

00:29:46are usually sealed

00:29:47with foil

00:29:47and it's better

00:29:48to avoid opening it

00:29:49with fingers

00:29:49unless you're ready

00:29:50to say goodbye

00:29:51to your nails.

00:29:52A point easily opens

00:29:54even the most

00:29:54safely sealed tube.

00:29:58Silica gel

00:29:59can often be found

00:30:00in different things

00:30:00you buy

00:30:01like bags,

00:30:02shoes

00:30:02and many others.

00:30:03Don't throw it away.

00:30:05It's meant to absorb

00:30:05excess moisture

00:30:06so anytime your shoes

00:30:08are a bit wet,

00:30:09just throw in a packet

00:30:10with silica gel.

00:30:13People

00:30:13used to co-live

00:30:14with rats

00:30:15and these guys

00:30:16like gnawing

00:30:17on everything they see

00:30:18in their way

00:30:18including paper.

00:30:20Still,

00:30:21rats weren't able

00:30:22to chew more than

00:30:23the space left

00:30:23on the margins.

00:30:26That black grate

00:30:28on a microwave

00:30:28isn't just

00:30:29some fancy decoration.

00:30:30It's called

00:30:31a Faraday shield

00:30:32and it prevents

00:30:33the rays

00:30:33from escaping

00:30:34the microwave.

00:30:35It also speeds up

00:30:36the heating

00:30:36so you can enjoy

00:30:37yesterday's leftovers

00:30:38faster.

00:30:40It may also

00:30:41block phone signals

00:30:42so if you're tired

00:30:43of numerous calls

00:30:44just put the phone

00:30:45into a microwave

00:30:45but don't turn it on.

00:30:50All Tic Tac containers

00:30:52are designed

00:30:52to dispense

00:30:53one Tic Tac

00:30:54every time

00:30:55you open it.

00:30:55The lid has

00:30:56the same shape

00:30:57as the candy.

00:30:58Turn the container

00:30:58upside down,

00:30:59gently shake it

00:31:00and open it slowly.

00:31:01You'll notice

00:31:02only one candy

00:31:03stuck between

00:31:03those lid grooves.

00:31:05So if you just

00:31:06open the container

00:31:06and shake it

00:31:07until five

00:31:08or even more candies

00:31:09fall into your mouth

00:31:10it means

00:31:10you've been eating

00:31:11Tic Tacs wrong

00:31:12all this time.

00:31:17Those little holes

00:31:18in the airplane windows

00:31:19are designed

00:31:20to control

00:31:20the cabin pressure.

00:31:21They also protect

00:31:22the windows

00:31:23from fogging up

00:31:23as the temperatures

00:31:24drop and rise.

00:31:25By the way

00:31:26the airplane window

00:31:27is round for a reason.

00:31:28This way

00:31:29pressure is evenly

00:31:30distributed

00:31:30so it doesn't

00:31:31get deformed.

00:31:34Blue bristles

00:31:35on a toothbrush

00:31:36are actually

00:31:37an indicator

00:31:37that it's just

00:31:38about time

00:31:38to change the brush.

00:31:40As the bristles

00:31:41get in contact

00:31:41with water

00:31:42the blue

00:31:43or whatever other

00:31:44pigment fades away

00:31:45so the more

00:31:46you use it

00:31:46the duller

00:31:47the color

00:31:48becomes.

00:31:50A triple handle

00:31:51on a jerry can

00:31:52is there

00:31:52to make it easier

00:31:53for two people

00:31:54to carry it

00:31:54and distribute

00:31:55the fuel evenly.

00:31:56Gas cans

00:31:56often have

00:31:57a second hole

00:31:58that actually

00:31:58needs to be

00:31:59unkept too

00:32:00before you

00:32:00pour the gas.

00:32:01The air passage

00:32:02will prevent it

00:32:03from pouring out

00:32:04so no more

00:32:05fuel waste.

00:32:07Jeans

00:32:08first appeared

00:32:09in 1873.

00:32:10They were invented

00:32:11by Jacob Davis

00:32:12and Levi Strauss.

00:32:14Davis was a tailor

00:32:15who was producing

00:32:16covers and tents.

00:32:17and Strauss

00:32:18was a businessman

00:32:19who among other things

00:32:21was selling cloth.

00:32:22The first jeans

00:32:23were made by Davis

00:32:25from denim

00:32:25the fabric he bought

00:32:27from Levi Strauss

00:32:28and co.

00:32:29Together

00:32:29they patented

00:32:30the design.

00:32:31Blue was a standard

00:32:32color for denim

00:32:33that was dyed

00:32:34using an indigo dye.

00:32:36The blue color

00:32:37is a tradition

00:32:37that is still

00:32:38often followed today

00:32:39to replicate

00:32:39the original look

00:32:40of a pair of jeans.

00:32:42Jeans also have

00:32:43metal rivets

00:32:44and they've been there

00:32:45from the very beginning.

00:32:46Jacob Davis

00:32:47the man who made

00:32:48the first pair of jeans

00:32:48added copper rivets

00:32:50to spots where pants

00:32:51were more likely

00:32:52to rip

00:32:52flies and pockets

00:32:54to make them stronger.

00:32:55Today

00:32:56they have more

00:32:57of a decorative purpose

00:32:58since they're distinctive

00:32:59and traditional

00:33:00for jeans.

00:33:02Another special thing

00:33:03about jeans

00:33:04is those tiny pockets

00:33:05they have

00:33:05that seemingly

00:33:06serve no purpose.

00:33:08Well

00:33:08maybe it's true now

00:33:09but years ago

00:33:10when many cowboys

00:33:11were wearing jeans

00:33:11the pocket was made

00:33:13specifically

00:33:13to keep a pocket watch

00:33:15there.

00:33:16Also

00:33:16back then

00:33:17a pair of jeans

00:33:18had just four pockets

00:33:19that tiny pocket

00:33:20the watch pocket

00:33:21two big pockets

00:33:22in front

00:33:23and just one pocket

00:33:24on the back.

00:33:27Many zippers

00:33:28have the letters

00:33:29YKK

00:33:29engraved on them.

00:33:31It's an abbreviation

00:33:32that stands for

00:33:33the name of the company

00:33:34that can be translated

00:33:35as

00:33:36Yoshida Manufacturing

00:33:37Shareholding Company.

00:33:39This Japanese company

00:33:40is the largest zipper

00:33:41manufacturer

00:33:42in the world

00:33:42so they put their initials

00:33:44on all the zippers

00:33:45they produce.

00:33:46That's around half

00:33:46of the zippers

00:33:47in the world

00:33:48and that's why

00:33:49you see their zippers

00:33:50more often

00:33:51than any other zippers.

00:33:54Those little white golf balls

00:33:55have dimples

00:33:56all over them.

00:33:57It turns out

00:33:57they aren't there

00:33:58just randomly.

00:33:59At first

00:33:59golfers were playing

00:34:00with a smooth ball.

00:34:01With time

00:34:02the ball would get

00:34:03all punched

00:34:04and damaged

00:34:05but also

00:34:05it would start

00:34:06to travel way further.

00:34:07The reason here

00:34:08is aerodynamics.

00:34:10Dimples allow

00:34:11the air

00:34:11to flow more smoothly

00:34:13around the ball

00:34:13taking it further

00:34:14so the idea

00:34:15was adopted

00:34:16and the balls

00:34:17got their dimples

00:34:17all around

00:34:18allowing them

00:34:19to travel

00:34:19longer distances.

00:34:22From the iconic

00:34:24golden fries

00:34:24to a broken

00:34:25ice cream machine

00:34:26here are 10

00:34:27fast food secrets

00:34:28that the fast food

00:34:29industry

00:34:30doesn't really

00:34:30want you to know.

00:34:32Ah, chicken nuggets.

00:34:33Those golden crispy bites

00:34:35you can get

00:34:35from fast food chains.

00:34:37They're even on the menu

00:34:38of school lunches.

00:34:39What if I tell you

00:34:40that they aren't

00:34:41actually made

00:34:42entirely out of chicken?

00:34:44Researchers took

00:34:45chicken nugget samples

00:34:46from unnamed

00:34:47fast food chains

00:34:47and analyzed them.

00:34:49They said that

00:34:49one sample

00:34:50for instance

00:34:51contained only 40%

00:34:52and another

00:34:5350% of meat.

00:34:55The rest?

00:34:56Well,

00:34:56you're eating mouthfuls

00:34:58of things like fat,

00:34:59connective tissue

00:35:00and bone spicules.

00:35:02Many fast food companies

00:35:03grind the meat

00:35:04with that stuff.

00:35:05They make

00:35:06mechanically formed

00:35:06orbs of chicken parts.

00:35:08Why?

00:35:09Perhaps it's because

00:35:10this method is cheaper

00:35:11and more profitable.

00:35:13Millions of restaurants

00:35:14worldwide have

00:35:15chicken nuggets

00:35:15on their menu.

00:35:16So,

00:35:17scientifically,

00:35:18it's not fair to say

00:35:19all nuggets are made

00:35:20this way.

00:35:20But a lot of studies

00:35:22imply so.

00:35:23The more the meat

00:35:24is processed,

00:35:25the more you lose

00:35:26the good stuff

00:35:27like vitamin B6

00:35:28and B12.

00:35:29The bitter truth

00:35:30is that companies

00:35:31add stuff

00:35:32such as sodium

00:35:33to the mixed paste.

00:35:35Sodium is added

00:35:36to get a better flavor.

00:35:37It's one of the ingredients

00:35:38that makes nuggets

00:35:39so yummy.

00:35:40Our bodies need sodium

00:35:42but not too much of it.

00:35:44Unfortunately,

00:35:45most junk food

00:35:45contains more

00:35:46than our bodies

00:35:47can handle.

00:35:48So,

00:35:48it might be a safe option

00:35:50to avoid eating

00:35:51these sorts of foods

00:35:52frequently.

00:35:53Chains dip their nuggets

00:35:54into tempura batter

00:35:55and fry them

00:35:56in hydrogenated oil.

00:35:58That's also not

00:35:59a green light

00:36:00regarding health

00:36:01but this is how

00:36:02they catch

00:36:02the golden tint.

00:36:04They put additional

00:36:05stuff in nuggets.

00:36:07What about grilled chicken?

00:36:08In recent years,

00:36:09we've seen brands

00:36:10highlighting grilled chicken

00:36:11as a healthier option.

00:36:12Research has been done

00:36:14about grilled chicken too.

00:36:16And the same approach

00:36:17is applied here.

00:36:18Take chicken samples

00:36:19from iconic fast food companies

00:36:21and send those

00:36:22to labs for analysis.

00:36:24The results show

00:36:25that companies

00:36:26are misleading people

00:36:27by advertising

00:36:28these products

00:36:29by labeling them

00:36:30as healthy,

00:36:31natural,

00:36:32and 100% chicken breast.

00:36:34In reality,

00:36:35a couple of things

00:36:36are added to the meat

00:36:37to make it tender

00:36:38and juicy.

00:36:39Plus,

00:36:39these additives

00:36:40make it easier

00:36:41to cook the meat,

00:36:42freeze,

00:36:43and transport it

00:36:43and reheat it later

00:36:45without losing

00:36:45too much moisture.

00:36:47The drawback

00:36:48of all these additives

00:36:49is that they affect

00:36:50the nutritional value

00:36:51of the chicken breast.

00:36:53These ingredients

00:36:54aren't the healthiest

00:36:55for us.

00:36:55We should especially

00:36:56watch out for three things.

00:36:58The first one

00:36:59is again,

00:37:00sodium.

00:37:00Fast food samples

00:37:01had 7 to 10 times

00:37:03more sodium

00:37:03than home-cooked

00:37:04chicken breast.

00:37:06Imagine you have

00:37:07a cheeseburger,

00:37:07but you say no

00:37:08to yourself

00:37:09and try to pick

00:37:10a less harmful menu item.

00:37:11Yet,

00:37:12some chicken sandwiches

00:37:13have the same amount

00:37:14or even more sodium

00:37:16than a cheeseburger

00:37:16with medium fries.

00:37:18The second thing

00:37:19you need to watch out for

00:37:20is phosphate additives.

00:37:22These additives

00:37:23allow the protein

00:37:24to conjoin more water.

00:37:26This means

00:37:27the white meat

00:37:27in the sandwich

00:37:28will appear

00:37:29juicier to you.

00:37:30Any word you see

00:37:31in the ingredients section

00:37:32that contains

00:37:33FOSS

00:37:33is a phosphate additive,

00:37:35so it's best

00:37:36to avoid them.

00:37:38The last thing

00:37:39you should avoid

00:37:39is sugars

00:37:40and starches,

00:37:41not just in grilled chicken,

00:37:42but pretty much

00:37:43in all fast food products.

00:37:45Oh, that's hard

00:37:46to digest,

00:37:47I admit.

00:37:47Cornstarch,

00:37:48sugar,

00:37:49malt,

00:37:49they come with

00:37:50grilled chicken breast.

00:37:51Buns,

00:37:52and even some fries

00:37:53have sugar too.

00:37:55Everywhere I look,

00:37:56it's sugar.

00:37:57You see,

00:37:58home-cooked chicken

00:37:59has zero grams of carbs,

00:38:00but the study samples

00:38:01had added sugar

00:38:02and up to 10%

00:38:03of the calories

00:38:04in the chicken breast

00:38:05comes from there.

00:38:06So what's the moral

00:38:07of this story?

00:38:08If you're a health-conscious diner,

00:38:10you should maybe

00:38:11go for other options.

00:38:13There are secret recipes

00:38:15from companies

00:38:15like KFC

00:38:16and Coca-Cola.

00:38:18No company wants

00:38:19to share the ingredients

00:38:20that make their food

00:38:21irresistible,

00:38:22but with a little research,

00:38:23you can decipher

00:38:24many things.

00:38:25You want to know

00:38:26the secret

00:38:27of McDonald's fries?

00:38:28It's written

00:38:29on their website.

00:38:30They add beef flavoring

00:38:32to the frying oil.

00:38:33This may sound weird,

00:38:34but apparently,

00:38:35that's a known practice

00:38:36amongst chefs

00:38:37and restaurants.

00:38:38Duck fat

00:38:39has also been used

00:38:40as a flavor,

00:38:41for example,

00:38:42in high-end restaurants.

00:38:44I'm a fries lover,

00:38:45so I added another fact

00:38:47about fries.

00:38:48Sadly,

00:38:49they're even saltier

00:38:50than you think.

00:38:51Experts suggest

00:38:52that a grown-up

00:38:53should consume

00:38:53at most

00:38:542,300 milligrams

00:38:56of sodium daily.

00:38:57Guess the McD's

00:38:58large fry sodium number?

00:39:00At least 400 milligrams.

00:39:03Classic fries

00:39:04from Burger King

00:39:04have 732 milligrams,

00:39:07and Five Guys

00:39:08take the level

00:39:09even higher

00:39:09with 962 milligrams

00:39:12of sodium.

00:39:13Next time,

00:39:14maybe you can ask workers

00:39:15to go easy

00:39:16on the salt

00:39:17as a solution.

00:39:19Picture this.

00:39:20You're in a hurry,

00:39:21but your tummy says,

00:39:22feed me,

00:39:22or I'll affect your mood

00:39:24and make life

00:39:24miserable for you.

00:39:26For a quick snack,

00:39:27you enter a fast-food

00:39:28chain restaurant.

00:39:29You order

00:39:30your favorite burger.

00:39:31It looks and smells

00:39:32as if it's just been

00:39:33taken from the grill

00:39:34and served.

00:39:35Nope.

00:39:36They have different types

00:39:37of grills

00:39:37designed for this

00:39:38that can cook meat

00:39:39super quickly.

00:39:40Sorry to bear

00:39:41the bad news,

00:39:42but those perfect

00:39:43grill marks on your burger

00:39:44aren't real tools.

00:39:45The factory adds them.

00:39:48If you want to know

00:39:49how clean an eatery is,

00:39:51look under the ice chute

00:39:52of the soda machine

00:39:53in places where you can

00:39:54get your own drink.

00:39:55There you go,

00:39:56inspector.

00:39:56You solved the case.

00:39:58Various studies say

00:39:59that if such machines

00:40:00aren't cleaned correctly,

00:40:02dirty, contaminated ice

00:40:03can lead to some

00:40:04health problems.

00:40:05There could be mold

00:40:07or bacteria there.

00:40:08Ew.

00:40:09The process of cleaning

00:40:10ice machines

00:40:11isn't easy.

00:40:12The same thing applies

00:40:13to ice cream machines, too.

00:40:14Rumor has it

00:40:15that those ice cream

00:40:16machines aren't

00:40:17out of order.

00:40:18Employers just cannot

00:40:19find time to clean

00:40:20them properly.

00:40:21Now, what's the best

00:40:23time to get a good

00:40:24and fresh meal?

00:40:25Here are two opinions,

00:40:26and they both have

00:40:27solid reasonings.

00:40:28The first team recommends

00:40:30avoiding ordering

00:40:31grilled food in chains

00:40:32from 7 to after midnight.

00:40:35Many former employees

00:40:36say that sometimes

00:40:37they had taquitos

00:40:38or hot dogs prepared

00:40:39at around 4 or 5 a.m.,

00:40:41but kept waiting to serve them

00:40:43till around midnight.

00:40:44That's not healthy.

00:40:46The other team says

00:40:47you should order

00:40:48between 11 a.m.

00:40:49and 1 p.m.,

00:40:50or between 6 p.m.

00:40:51and 8 p.m.

00:40:52to get the freshest meal.

00:40:54Since it's going to be

00:40:55around lunch

00:40:56and dinner time,

00:40:57there'll be circulation

00:40:58and you can get

00:40:59decent food.

00:41:00Fast food companies

00:41:02have marketing,

00:41:03design,

00:41:03and psychological tricks

00:41:04to lure you in

00:41:06and make you order,

00:41:07yet they don't want you

00:41:08to stay inside

00:41:09for too long.

00:41:10If you were dining

00:41:11in mood lighting,

00:41:12you know under dim lamps

00:41:14and candlelight

00:41:14you would take your time

00:41:15to eat.

00:41:16As the name suggests,

00:41:17you should be fast

00:41:18like your food

00:41:19in chain restaurants.

00:41:20They have fluorescence

00:41:22and they're in full light.

00:41:24Similarly,

00:41:25the floors and tables

00:41:26have reflective surfaces

00:41:27that make food

00:41:28look nice and bright.

00:41:30Plus,

00:41:31music is usually fast

00:41:32and loud.

00:41:33It's done to prevent you

00:41:34from spending hours there,

00:41:36yet they want you

00:41:37to take advantage

00:41:38of the first 20 minutes

00:41:39after your purchase.

00:41:41The faster you eat,

00:41:42the longer it will take you

00:41:43to feel full.

00:41:45Scientists say

00:41:46it takes about 20 minutes

00:41:47for our stomachs

00:41:48to inform our brain,

00:41:49okay,

00:41:50now I'm full.

00:41:52It's a good idea

00:41:53to eat in a clean area,

00:41:55but most of these companies

00:41:56are using cleaning products

00:41:57that have super strong chemicals.

00:42:00Assume that the staff

00:42:01clean the place

00:42:02at the end of their shift.

00:42:03They wipe down the soda machine

00:42:05and grill surface,

00:42:06and then you showed up

00:42:07early the next day.

00:42:09You may get some

00:42:10of that chemical residue

00:42:11on your food

00:42:12compared to other customers

00:42:13visiting the place

00:42:14later in the day.

00:42:16The vegan patty

00:42:17may not be 100% vegan.

00:42:19I'm talking about the grill,

00:42:21not the meat itself.

00:42:22In most of the chains,

00:42:24vegan burgers

00:42:24are cooked on the same grill

00:42:26as meat burgers.

00:42:28Do you have fast food chain secrets

00:42:30you want to share?

00:42:31Tell them to fellow

00:42:32bright siders

00:42:32in the comments.

00:42:37Bet you've never heard

00:42:38of corrugation.

00:42:40It's a system

00:42:40that may lie hidden

00:42:41in your pantry right now.

00:42:45Ever notice those bumps

00:42:47on food cans?

00:42:48That's exactly

00:42:49what they're called.

00:42:50And they're not

00:42:50just for aesthetics.

00:42:52First off,

00:42:53they make the can

00:42:54extra strong.

00:42:55That's because

00:42:56they can help it

00:42:57from cracking

00:42:57during the manufacturing process.

00:43:00Plus,

00:43:01these corrugations

00:43:02come in handy

00:43:03during delivery,

00:43:04acting like a shield

00:43:05to make sure

00:43:06there's no spillage.

00:43:07They're also useful

00:43:09in the long run

00:43:10because they help

00:43:10keep the cans

00:43:11in their original shape.

00:43:13Even when things

00:43:14get too hot

00:43:15or too cold,

00:43:16these corrugations

00:43:17let them breathe a bit.

00:43:18They expand

00:43:19and contract

00:43:20without breaking the metal.

00:43:21You may not notice

00:43:23any cracks

00:43:23on regular cans,

00:43:25but even the tiniest

00:43:26of openings

00:43:27can leave a way

00:43:27for nasty bacteria

00:43:29to get in contact

00:43:30with the food.

00:43:31Not to mention,

00:43:33they create

00:43:33this little air gap.

00:43:35So when you pop

00:43:35the can open,

00:43:37everything slides out

00:43:38smoothly

00:43:38without you having

00:43:39to put in

00:43:40that much effort.

00:43:41You know what

00:43:42also doesn't

00:43:43require much effort?

00:43:44Hitting that subscribe

00:43:45button

00:43:45and liking this video.

00:43:50You know

00:43:51there's a plant

00:43:51out there

00:43:52that's so eager

00:43:53to reach the sun

00:43:53you can hear it grow?

00:43:56Rhubarb

00:43:56just before it's picked

00:43:57from the fields

00:43:58soaks up

00:43:59all the sun rays

00:44:00it can get

00:44:01to make glucose.

00:44:02After this sunbathing session,

00:44:04it gets transported

00:44:05to dark sheds.

00:44:07Inside,

00:44:08it keeps on growing

00:44:09and uses the stored glucose

00:44:11as fuel.

00:44:12Nothing out of the ordinary

00:44:13so far,

00:44:14but in that dark,

00:44:16cozy,

00:44:16and warm place,

00:44:18rhubarb

00:44:18starts acting weird.

00:44:20That environment

00:44:21pushes the plant

00:44:22to stretch itself out

00:44:23in hopes

00:44:24it will find sun rays again.

00:44:27It happens so fast

00:44:29that you can

00:44:30actually hear

00:44:31the buds

00:44:31and stalks

00:44:32making noise

00:44:33as they pop open.

00:44:35To make sure

00:44:35this process

00:44:36goes smoothly,

00:44:37there's no light

00:44:38allowed.

00:44:40If light hits

00:44:41the rhubarb

00:44:42at this point,

00:44:43it will start

00:44:43photosynthesizing again

00:44:45and go bitter.

00:44:49Speaking of

00:44:50everyday groceries,

00:44:51you might have noticed

00:44:52that veggie bags

00:44:53come with some

00:44:54green stripes.

00:44:55Know that

00:44:56it's a sneaky

00:44:57optical trick.

00:44:58Those stripes

00:44:59fool our eyes

00:45:00into believing

00:45:01the veggies

00:45:01look way greener

00:45:03than they are.

00:45:03And it's not

00:45:04just veggies

00:45:05that get this

00:45:06special packaging.

00:45:07Oranges

00:45:08are often sold

00:45:09in red mesh bags

00:45:10for the same reason.

00:45:12Lemons?

00:45:13They go for yellow

00:45:14or green bags

00:45:15for that same

00:45:16pop of color.

00:45:18If your cooking

00:45:19skills aren't

00:45:20that good

00:45:20and you're just

00:45:21afraid you're

00:45:21going to mess

00:45:22up dinner

00:45:22yet again,

00:45:24stick to mushrooms.

00:45:25That's because

00:45:25they're almost

00:45:26impossible to

00:45:27overcook.

00:45:28Unlike other

00:45:29vegetables that

00:45:30turn into mush

00:45:31when overcooked,

00:45:32mushrooms are

00:45:33way more resistant.

00:45:35They've got this

00:45:36interesting substance

00:45:37called chitin,

00:45:38a molecular structure

00:45:39that works

00:45:40like an armor.

00:45:41So you can cook

00:45:43them forever.

00:45:43They won't burn.

00:45:48Donuts don't

00:45:49have holes in them

00:45:50because it's easier

00:45:51for you to pick

00:45:52them up.

00:45:52If you've ever

00:45:53tried to make

00:45:53them at home,

00:45:54you might have

00:45:55noticed that when

00:45:55you fry the dough,

00:45:57the outside gets

00:45:58done quickly,

00:45:58thanks to the

00:45:59hot oil.

00:46:00If you want the

00:46:01inside to look

00:46:02just as good,

00:46:03you have to keep

00:46:04it in the oil

00:46:04way longer,

00:46:05but then the

00:46:06outside would get

00:46:07too brown.

00:46:09Thanks to that

00:46:10middle hole,

00:46:10the heat gets

00:46:11to both sides

00:46:12equally,

00:46:13cooking up a

00:46:13flawless donut.

00:46:17Here's how that

00:46:18small piece of

00:46:19paper makes it

00:46:20into your fortune

00:46:21cookie.

00:46:21First, they bake

00:46:23these cookies

00:46:23flat like pancakes.

00:46:25Then, while

00:46:26they're still warm

00:46:26and bendy,

00:46:27they sneak in

00:46:28those tiny messages.

00:46:29As the cookies

00:46:30cool down,

00:46:31they toughen up

00:46:32and keep their

00:46:32shape, trapping

00:46:34the fortune inside

00:46:35like a tasty

00:46:36time capsule.

00:46:37One legend has it

00:46:38that these Asian

00:46:40treats were

00:46:40initially intended

00:46:41to help people

00:46:42send all sorts

00:46:43of secret messages

00:46:44without causing

00:46:45any suspicion.

00:46:47Here's a little

00:46:48tip for whenever

00:46:49you're buying lunch

00:46:50at a fast food

00:46:50place.

00:46:51Skip the word

00:46:52extra when

00:46:53you're ordering.

00:46:54The moment you

00:46:55speak that term,

00:46:56you're tempting

00:46:57the employees

00:46:57to charge more.

00:46:59Instead, go for

00:47:00something like

00:47:01a little more

00:47:02please when

00:47:02you're getting

00:47:03a special

00:47:03burrito bowl.

00:47:07According to

00:47:08a UK study,

00:47:09cheese is the

00:47:10most stolen

00:47:11of foods

00:47:12worldwide.

00:47:13It's estimated

00:47:13that around 4%

00:47:15of all cheese

00:47:15just vanishes

00:47:16from stores.

00:47:17And no,

00:47:19it's not mice

00:47:19doing the stealing,

00:47:20it's people.

00:47:21Why?

00:47:22Because cheese

00:47:23is becoming

00:47:24more and more

00:47:25valuable.

00:47:26The price of cheese

00:47:27is constantly

00:47:27going up and

00:47:29sneaky thieves

00:47:29are trying to

00:47:30make easy money

00:47:31by simply taking

00:47:32it from the racks.

00:47:33It's not just

00:47:34cheese though.

00:47:35Other interesting

00:47:36items on the

00:47:37thieving list

00:47:37include fresh meat,

00:47:39chocolate,

00:47:40and seafood.

00:47:43Ferreira,

00:47:43the company

00:47:44behind those

00:47:45luscious jars

00:47:46of Nutella,

00:47:47needs about

00:47:4725% of the

00:47:49world's hazelnuts

00:47:50every year.

00:47:52So if you think

00:47:53about it,

00:47:531 in 4 hazelnuts

00:47:55ends up in a

00:47:55chocolatey jar.

00:47:57The manufacturers

00:47:58get the nuts

00:47:59from Turkey,

00:48:00Italy,

00:48:00and Chile,

00:48:01making sure

00:48:02they get them

00:48:02delivered from

00:48:03both the northern

00:48:04and southern

00:48:04hemispheres

00:48:05to keep things

00:48:06fresh.

00:48:07Nutella's impact

00:48:08on the economy

00:48:08is even bigger

00:48:09than you'd imagine.

00:48:11Because of this

00:48:12demand,

00:48:13the price of

00:48:13hazelnuts

00:48:14went through

00:48:15the roof.

00:48:16In 2014,

00:48:17a frost hit

00:48:18Turkey's hazelnuts,

00:48:19supply got

00:48:20halved,

00:48:21and prices

00:48:22were even higher.

00:48:23Now,

00:48:24even places

00:48:25like New Jersey

00:48:26are trying to

00:48:27grow those

00:48:27Nutella-worthy

00:48:28nuts.

00:48:32When you

00:48:32imagine someone

00:48:33trying to sneak

00:48:34something into

00:48:35space,

00:48:35your first thought

00:48:36wouldn't be

00:48:37a sandwich.

00:48:38But back

00:48:39in 1965,

00:48:40during a Gemini

00:48:41mission,

00:48:42astronaut John

00:48:43Young brought

00:48:44a corned beef

00:48:44sandwich on

00:48:45board,

00:48:46going against

00:48:47NASA rules.

00:48:48He hid it in

00:48:49his spacesuit

00:48:50pocket before

00:48:51blast-off.

00:48:52About two hours

00:48:53into the five-hour

00:48:54trip,

00:48:54he went to the

00:48:55mission commander

00:48:56and offered him

00:48:56this unlawful

00:48:58treat.

00:48:58The commander,

00:48:59being a good

00:49:00sport,

00:49:00took it,

00:49:01and they shared

00:49:02a quick,

00:49:02savory moment.

00:49:03He even put

00:49:04the unfinished

00:49:05sandwich in his

00:49:06own spacesuit pocket

00:49:07to avoid crumbs

00:49:08making a mess

00:49:09of the spacecraft.

00:49:10Meanwhile,

00:49:11the official

00:49:12NASA-approved

00:49:13food was

00:49:14waiting patiently

00:49:15in a box

00:49:15nearby.

00:49:18Surely,

00:49:19radishes aren't

00:49:19your first pick

00:49:20when it comes

00:49:21to salad ingredients,

00:49:22but they have

00:49:23quite an interesting

00:49:24history, too.

00:49:25These mustard,

00:49:26broccoli,

00:49:27cabbage,

00:49:27and cauliflower

00:49:28cousins have

00:49:29been grown and

00:49:30eaten for longer

00:49:31than you'd imagine,

00:49:32even before the

00:49:33Romans were famous

00:49:34in ancient

00:49:35Egyptian times.

00:49:36In fact,

00:49:38radishes were

00:49:38used as currency

00:49:39for the people

00:49:40who built the

00:49:40pyramids,

00:49:41alongside onions

00:49:42and garlic.

00:49:46You'd think

00:49:47the English

00:49:47are champions

00:49:48when it comes

00:49:49to drinking tea,

00:49:50but you'd be

00:49:51wrong.

00:49:52Turkey is,

00:49:52in fact,

00:49:53the tea capital

00:49:54of the world.

00:49:55Every Turk

00:49:56drinks an average

00:49:57of 1,300 cups

00:49:58of tea each year.

00:50:00On a regular day,

00:50:01they're sipping

00:50:02on 3 to 5 cups,

00:50:04but when winter

00:50:05hits,

00:50:05they can reach

00:50:0610 cups a day.

00:50:08Locals claim

00:50:09tea is like

00:50:10a social custom

00:50:10for them.

00:50:11It's more than

00:50:12just a hot beverage.

00:50:13It's an excuse

00:50:14to sit down,

00:50:15enjoy the atmosphere,

00:50:16and connect

00:50:17with loved ones.

00:50:18When it comes

00:50:18to types,

00:50:19black tea is preferred.

00:50:21There might be

00:50:22a magical drink

00:50:23hidden in your fridge.

00:50:25It's tonic water,

00:50:26and it might be able

00:50:28to glow in the dark.

00:50:29If you're curious,

00:50:30test it out

00:50:31with some ultraviolet light.

00:50:33The secret behind

00:50:34this glow

00:50:34is pretty simple.

00:50:36Tonic water

00:50:37has quinine,

00:50:38a chemical

00:50:39that lights up

00:50:40under certain conditions.

00:50:42Quinine was used

00:50:43back in the day

00:50:44to treat certain

00:50:44health problems.

00:50:45The stuff was so bitter

00:50:47that some people

00:50:48started mixing it

00:50:49with sugar and soda water.

00:50:50In simple terms,

00:50:52things glow

00:50:52because they absorb

00:50:53light energy,

00:50:55gets all excited,

00:50:56and then releases it

00:50:58as visible light.

00:50:59Quinine in tonic water

00:51:00absorbs and releases energy,

00:51:02making your drink

00:51:03look like it's

00:51:04from a fairy tale.

00:51:08There's an interesting

00:51:10connection between

00:51:10what we hear

00:51:11and what we taste.

00:51:13Scientists investigated

00:51:14and found that

00:51:15people worldwide

00:51:16link certain sounds

00:51:18with specific flavors,

00:51:19and they call it

00:51:20cross-modal correspondence.

00:51:22High-pitched sounds

00:51:23match up with sweet

00:51:25and sour tastes,

00:51:26while the lower,

00:51:27jarring sounds

00:51:28go hand-in-hand

00:51:29with bitterness.

00:51:30If it's staccato,

00:51:32think crunchy,

00:51:33and if it's smooth

00:51:34and flowing,

00:51:35think creamy.

00:51:36Some even found music

00:51:38that can enhance

00:51:38the taste of chocolate.

00:51:40In this study,

00:51:41when people listen

00:51:42to a high-pitched,

00:51:44sweet soundtrack

00:51:44while eating chocolate,

00:51:46they thought it was sweeter

00:51:47than when they'd heard

00:51:48a lower,

00:51:48more dissonant soundtrack.

00:51:56So, consider this.

00:51:58People started making

00:51:59ridge patterns on coins

00:52:01in past centuries

00:52:01to fight counterfeiters.

00:52:03In the old days,

00:52:05cheaters cut off

00:52:06the smooth edges of coins

00:52:07and used that metal

00:52:08to mint new money.

00:52:09But with ridges,

00:52:11it became impossible

00:52:12to hide the cutting.

00:52:13These small cylinders

00:52:15on the charging cables

00:52:16are called chokes

00:52:17or ferrite cores.

00:52:18They're magnetic iron oxide

00:52:21that helps to prevent

00:52:22electromagnetic interference.

00:52:24In simple words,

00:52:25they protect your device

00:52:26from faults.

00:52:27We all know about

00:52:29these little pockets

00:52:30on jeans

00:52:30where people used to

00:52:31keep their pocket watches.

00:52:33But what about

00:52:33these small metal buttons?

00:52:35They help hold

00:52:36the fabric together.

00:52:37Weavers put the buttons

00:52:39where the jeans can tear

00:52:40during moving and straining.

00:52:42These small holes

00:52:43on some backpacks

00:52:44were designed to tie

00:52:45extra gear to them

00:52:46so you can pass ropes

00:52:48through them

00:52:49and tie sneakers

00:52:49if you don't want

00:52:50to keep them

00:52:51inside your backpack

00:52:52or in your hands.

00:52:54This tiny dot

00:52:55next to the camera

00:52:56on your iPhone

00:52:57is a microphone.

00:52:58It helps to get

00:52:59good quality of sound

00:53:00while taking a video.

00:53:02The Spotlight feature

00:53:03on your Mac

00:53:04can be used

00:53:05not only for a quick search

00:53:07of files and apps.

00:53:08It also works

00:53:09as a calculator.

00:53:10Just type in

00:53:11a mathematical problem

00:53:12you need to solve.

00:53:14Spotlight also uses

00:53:15internal dictionary data.

00:53:17Enter any word

00:53:18in the search bar

00:53:19and you can get

00:53:20information about it.

00:53:21You've just bought

00:53:22a new bottle of oil.

00:53:24You're taking off the lid

00:53:25and looking at this

00:53:26little cork

00:53:27that you can tear off

00:53:28by pulling the loop.

00:53:29Take this thing out

00:53:30but don't throw it

00:53:32in the trash.

00:53:32Put it back

00:53:33in an upside-down position

00:53:35to control the pour's flow

00:53:37by pressing your finger

00:53:38against it.

00:53:40Tiny ridges

00:53:41on the F and J

00:53:42keys on the keyboard

00:53:43help your fingers

00:53:44navigate during

00:53:45touch typing.

00:53:46When your index fingers

00:53:47are on these ridges

00:53:48you know exactly

00:53:50where other letters are.

00:53:51The brushes

00:53:52on the sides

00:53:53of the escalators

00:53:54are not for polishing

00:53:55your shoes

00:53:56but for your safety.

00:53:58These nylon bristles

00:53:59prevent your laces

00:54:00and clothes

00:54:01from getting inside

00:54:02the escalator's gears.

00:54:04No, that wouldn't be good.

00:54:06Most door handles

00:54:07are made of brass.

00:54:08This type of metal

00:54:09is good for fighting microbes.

00:54:11Bacteria can't multiply

00:54:13that much

00:54:13on such surfaces.

00:54:15These public toilet's

00:54:17cubicles

00:54:17don't look private

00:54:18for a reason.

00:54:19Huge gaps

00:54:20at the bottom

00:54:21were created

00:54:22to make you want

00:54:22to get out of there

00:54:23as soon as possible.

00:54:25Thanks to this design

00:54:26there are almost

00:54:27no cubes.

00:54:28You can use

00:54:29a plastic lid

00:54:30from soda cups

00:54:31as a coaster.

00:54:32It has the perfect shape

00:54:34to hold your drink

00:54:35and keep a table surface

00:54:36from getting wet.

00:54:37Don't turn the lid

00:54:38upside down.

00:54:39Just put it on the table

00:54:40the same way

00:54:41it was on the cup.

00:54:42If you're stuck

00:54:43in a car

00:54:44during an accident

00:54:45and can't open

00:54:46the doors

00:54:46you can use bars

00:54:48from the detachable

00:54:49headrest

00:54:49to break the window

00:54:50and get out.

00:54:52Remember those

00:54:53small plastic discs

00:54:54under the bottle lids?

00:54:56This little thing

00:54:57helps preserve vacuum

00:54:58inside bottles

00:54:59keeping soda

00:55:00in a fizzy state.

00:55:02You've probably

00:55:03watched food heating

00:55:04in a microwave

00:55:05at least once

00:55:06in your life.

00:55:06Exciting!

00:55:07I know!

00:55:08But why do

00:55:09the developers

00:55:10make the door

00:55:10so dark?

00:55:11This black film

00:55:12is necessary

00:55:13to block

00:55:14electromagnetic fields.

00:55:16Tiny dots

00:55:17on padlocks

00:55:18next to the keyhole

00:55:19are designed

00:55:20to dry out

00:55:20the moisture

00:55:21if water

00:55:22gets inside the lock.

00:55:23Also,

00:55:24if the lock

00:55:25gets jammed

00:55:25or starts to rust

00:55:26you can pour oil

00:55:28into it

00:55:28through this hole

00:55:29to fix the problem.

00:55:30A golf ball

00:55:32is covered

00:55:33with tiny craters

00:55:34for good aerodynamics.

00:55:35They're called dimples

00:55:37and this design

00:55:38helps the ball

00:55:39fly further

00:55:40and more evenly.

00:55:42Some mugs

00:55:43have a little groove

00:55:44at the outside

00:55:44of the bottom.

00:55:45It helps water

00:55:46flow out

00:55:47and prevents it

00:55:48from accumulating

00:55:49when the cup

00:55:49is in the dishwasher.

00:55:51Sunglasses

00:55:52were first used

00:55:53not to protect

00:55:54your eyes

00:55:54from the sun.

00:55:55They use such glasses

00:55:56during arctic expeditions.

00:55:58A huge amount of snow

00:56:00can blind you

00:56:01just like a bright flash.

00:56:02To save their eyes

00:56:04they came up

00:56:04with these

00:56:05unique glasses.

00:56:07You can use

00:56:07any t-shirt

00:56:08not only for dressing

00:56:09but also as a

00:56:10protective layer

00:56:11for your luggage.

00:56:12Just put your clothes

00:56:13on your suitcase

00:56:14as a cover

00:56:15and don't waste time

00:56:16plastic wrapping it.

00:56:18A button

00:56:19on the back

00:56:19of the shirt collar

00:56:20is there to keep

00:56:21your tie

00:56:21under the collar.

00:56:23Yes,

00:56:24people don't use it

00:56:24as intended

00:56:25because all ties

00:56:26are thinner now.

00:56:27But this button

00:56:28is still there

00:56:29as a decorative function.

00:56:31And here's the

00:56:32initial purpose

00:56:33of a tie.

00:56:34They created it

00:56:35in the 17th century

00:56:36Europe

00:56:37that tightened

00:56:37the collar.

00:56:38This way

00:56:39people protected

00:56:40their necks

00:56:40from a strong wind.

00:56:42Then

00:56:42they got used

00:56:43to this part

00:56:44of the outfit

00:56:44and made it

00:56:45a must-have accessory

00:56:46for royal gatherings.

00:56:48Soft pom-poms

00:56:50on hats

00:56:50were first invented

00:56:51several centuries ago.

00:56:53Sailors used them

00:56:54to avoid

00:56:55hitting their heads

00:56:55against low ship ceilings

00:56:57and ledges.

00:56:58They make most

00:56:59clothes hangers

00:57:00from cedar wood

00:57:01since it contains

00:57:02many natural oils

00:57:03repelling moths

00:57:04that love

00:57:05to eat your clothes.

00:57:07A light bulb

00:57:08is spherical

00:57:09because such a shape

00:57:10allows the light

00:57:11to distribute evenly.

00:57:13Also,

00:57:13such light bulbs

00:57:14are cheaper

00:57:15and easier to produce.

00:57:16Ever found

00:57:17these pieces of fabric

00:57:19in new clothes?

00:57:20They're not just patches

00:57:21but also testing subjects

00:57:23to use before washing.

00:57:24You can put this piece

00:57:26in the washing machine

00:57:27and see what happens

00:57:28to it.

00:57:29If everything is fine,

00:57:30then you can safely

00:57:31put your clothes in.

00:57:33Your ceiling fan

00:57:34has two modes of work,

00:57:36winter and summer.

00:57:37You need to find

00:57:38the switch on it.

00:57:39Push it up

00:57:40to activate

00:57:41the winter mode

00:57:41and down

00:57:42for the summer one.

00:57:44In summer mode,

00:57:45the fan pushes

00:57:46the air down.

00:57:47It pulls the air up

00:57:48in winter.

00:57:50Most people have

00:57:51this ground plunger

00:57:52in the bathroom.

00:57:53In movies,

00:57:54they use those

00:57:55to eliminate

00:57:55a blockage

00:57:56in the toilet.

00:57:57In fact,

00:57:58the plunger

00:57:58is to get rid

00:57:59of a blockage

00:58:00in the sink.

00:58:01For the toilet,

00:58:02you need another

00:58:03special device.

00:58:04The extra space

00:58:06under your oven

00:58:07is not for keeping

00:58:08pans and pies.

00:58:09You can put

00:58:10some dishes there.

00:58:11The heat of the stove

00:58:12will keep your meals warm.

00:58:14It's useful

00:58:15if you're waiting

00:58:15for friends

00:58:16late for dinner.

00:58:19You're taking

00:58:19a pack of popcorn

00:58:21out of a microwave

00:58:22after heating.

00:58:23See the little hole

00:58:24at the top

00:58:24of the popcorn bag?

00:58:26You can use it

00:58:27to get rid

00:58:27of small,

00:58:28unpopped grains.

00:58:29Shake the pack

00:58:30over the plate

00:58:31and all the grains

00:58:32will fall out

00:58:33through the hole.

00:58:34Almost all people

00:58:35use a travel pillow

00:58:36incorrectly.

00:58:38Usually,

00:58:38they put two ends

00:58:39forward

00:58:40and lay their heads back.

00:58:41Try to turn the pillow

00:58:43on the other side.

00:58:44The arc should be

00:58:45under your chin

00:58:46and the two ends

00:58:47should be directed back.

00:58:49Lay your head forward

00:58:50and your neck

00:58:51will feel

00:58:51way more comfortable

00:58:52in this position.

00:58:53And you'll get

00:58:55a good nap.

00:58:56They create magnets

00:58:57in a horseshoe shape

00:58:58to increase

00:58:59their magnetic power.

00:59:01The blue part

00:59:02indicates the south pole,

00:59:03the red part

00:59:04the north one.

00:59:05The two poles

00:59:06work simultaneously

00:59:07and increase

00:59:08the attraction.

00:59:10Thanks to the

00:59:11perfect aviation design,

00:59:12most planes

00:59:13can fly a long distance

00:59:15even without an engine.

00:59:16In 1268,

00:59:19Roger Bacon

00:59:19made the first

00:59:20written mention

00:59:21on using telescope lenses

00:59:23for optical purposes.

00:59:25Magnifying lenses

00:59:26inserted in frames

00:59:27were popular

00:59:28for reading

00:59:28both in Europe

00:59:29and China

00:59:30at this time.

00:59:31So,

00:59:31it's still a question

00:59:32if the West

00:59:33took it from the East

00:59:34or vice versa.

00:59:36If you find yourself

00:59:37in the middle of the sea

00:59:38without food,

00:59:39sorry,

00:59:40you can try

00:59:41fishing.

00:59:42You can use

00:59:43anything for bait,

00:59:44your phone,

00:59:45watch,

00:59:45keys

00:59:45and you can use

00:59:47laces as a fishing line.

00:59:48Tie the bait

00:59:49and throw it

00:59:50into the water

00:59:51and good luck

00:59:52catching the fish

00:59:53that swallowed your phone.

00:59:54It's going to be

00:59:55a whopper.

00:59:56You can turn over

00:59:57the tab

00:59:58on a lid of soda cans

00:59:59and use it

01:00:00to hold a cocktail

01:00:01straw in place.

01:00:03The blue half

01:00:04of the eraser

01:00:05wasn't originally

01:00:06created to delete

01:00:07the ink.

01:00:08Initially,

01:00:08the blue part

01:00:09erased inscriptions

01:00:10and drawings

01:00:10on thick paper.

01:00:11The red part

01:00:13couldn't do it

01:00:13without leaving streets

01:00:14but the blue one

01:00:15handled this task

01:00:16perfectly.

01:00:18Most of us

01:00:19tear sticking notes

01:00:20off incorrectly.

01:00:22Try not to do it

01:00:23from below

01:00:23but from the side

01:00:25along the licking lawn.

01:00:26The paper will stick

01:00:28to the wall

01:00:28for longer this way.

01:00:30Ever wondered

01:00:31what these two holes

01:00:32in the lollipop stick

01:00:33are for?

01:00:34All the time,

01:00:35you say?

01:00:36Well,

01:00:36when they put the bar

01:00:38in hot syrup,

01:00:39the liquid flows inside.

01:00:41It creates a solid

01:00:42attachment for the plastic.

01:00:44And so it goes.

01:00:48If you ever find yourself

01:00:50stuck in the trunk

01:00:51of your car,

01:00:51stay calm.

01:00:53All cars are supposed

01:00:54to be equipped

01:00:55with an emergency latch

01:00:56to help open the trunk

01:00:57from the inside

01:00:58in the unlikely case

01:01:00it happens.

01:01:01These latches

01:01:01are so well thought out

01:01:03that they can be opened

01:01:04by people of all ages.

01:01:06More so,

01:01:07handles are designed

01:01:07to glow in the dark, too.

01:01:09You can even pull them

01:01:10with the mouth

01:01:11if there's not enough

01:01:12wiggle room

01:01:12to use your hands.

01:01:14Never mind how you ended up

01:01:15in the trunk

01:01:16in the first place.

01:01:17Moving on!

01:01:18If you're ever working

01:01:19with needle and thread,

01:01:20remember,

01:01:21you don't need to stick

01:01:22the needle directly

01:01:23into the spool.

01:01:24You may end up

01:01:25losing the needle altogether.

01:01:27Not to mention,

01:01:28you can easily

01:01:28hurt your fingers!

01:01:30A lot of modern

01:01:31sewing kits these days

01:01:32come with a designated

01:01:33place for safeguarding

01:01:35the needles.

01:01:35It's located at the bottom

01:01:37part of the thread spool.

01:01:38You'll just need

01:01:39to pull it out.

01:01:40It's even made

01:01:41to hold multiple

01:01:42sewing needles at a time.

01:01:44Disposable ballpoint pens

01:01:46come with a little secret

01:01:47of their own.

01:01:48Did you ever notice

01:01:49that in some of them,

01:01:51there's a small hole

01:01:52in the plastic part?

01:01:53It's actually

01:01:54a rudimentary

01:01:55ventilation system.

01:01:56It's supposed to

01:01:57let the ink

01:01:58easily make it

01:01:59to the tip of the pen.

01:02:01Okay,

01:02:01I know it's in the name,

01:02:02but you really don't need

01:02:04to shake the seasoning shaker

01:02:05to get any product out.

01:02:07Don't believe me?

01:02:08Hey, you're not the only one.

01:02:10Go grab your favorite

01:02:11seasoning bottle

01:02:12out of your pantry.

01:02:13If it has one of those

01:02:15removable plastic caps,

01:02:16it's perfect for the experiment.

01:02:18Instead of shaking the bottle,

01:02:20try holding it from the plastic cap

01:02:22while it's upside down.

01:02:24Now, gently twist the bottle

01:02:26from side to side,

01:02:27and, before you know it,

01:02:29you get some

01:02:29gorgeously flowing seasoning

01:02:31without having to wiggle

01:02:32the shaker

01:02:33and make a mess

01:02:34all over the stove.

01:02:36On the same note,

01:02:37most salt and pepper shakers

01:02:39should have ridges

01:02:40on the bottom

01:02:41of the glass portion.

01:02:42In case you get

01:02:43any seasoning

01:02:44stuck in there,

01:02:45place the bottom

01:02:46of the salt shaker

01:02:46against the bottom

01:02:47of the pepper shaker

01:02:48and wiggle it around

01:02:50so the ridges

01:02:51click with each other.

01:02:52The seasoning

01:02:53should easily

01:02:53pour out now

01:02:54without you having

01:02:55to open the bottle.

01:02:57In colder weather,

01:02:58you often have

01:02:59so many clothing layers

01:03:00on you

01:03:01that you can hardly

01:03:02feel the purse

01:03:03or back straps

01:03:03on your shoulder anymore.

01:03:05Not to mention

01:03:06how fast

01:03:07they can slide off.

01:03:08Some jackets

01:03:09come with a built-in

01:03:10solution for that

01:03:11in the form

01:03:12of a small tab

01:03:13on the shoulder

01:03:13with either a hook

01:03:14or a button.

01:03:15It's meant to be

01:03:16opened and closed

01:03:17comfortably

01:03:18so you can keep

01:03:19your purse

01:03:19in place

01:03:20at any time.

01:03:22You're most likely

01:03:23using it

01:03:24merely to peel

01:03:25the skin of potatoes,

01:03:26carrots,

01:03:26or cucumbers.

01:03:27But you can use

01:03:29your vegetable peeler

01:03:30for chopping

01:03:31fine strips

01:03:31of onion as well.

01:03:33Just cut the onion

01:03:34into quarters vertically

01:03:35and then start slicing.

01:03:37This might also help out

01:03:39with those embarrassing

01:03:40onion tears.

01:03:42Most people miss this one,

01:03:43but should you ever

01:03:44have a closer look

01:03:45at your toothpaste tube,

01:03:47you will surely see

01:03:48some sort of coloring there,

01:03:50either a dot

01:03:51or a block.

01:03:52Colors can vary.

01:03:53They can be black,

01:03:54green,

01:03:55red,

01:03:55or even blue.

01:03:57These color spots

01:03:58are actually meant

01:03:58to help the assembly machines

01:04:00back of the toothpaste factory.

01:04:02They recognize

01:04:02when and where

01:04:03these machines

01:04:04need to cut

01:04:05the toothpaste tubes

01:04:06and proceed to fold them

01:04:07for packaging.

01:04:08For most types of footwear,

01:04:10if there's anything

01:04:11that seems a bit

01:04:12out of place,

01:04:13always know

01:04:14that it's there

01:04:14for a reason.

01:04:15Most manufacturers

01:04:16don't put extra items

01:04:18on shoes

01:04:18just for fun.

01:04:19It would definitely

01:04:20be a waste of time

01:04:21and resources.

01:04:23For footwear,

01:04:24like boots,

01:04:25for example,

01:04:25there's often

01:04:26a small loop

01:04:27at the top back

01:04:28of the shoe.

01:04:28It's there to help you

01:04:30when you need

01:04:30to put the shoe on

01:04:31since you can

01:04:32quickly pull on it.

01:04:33Plus,

01:04:34you can also hang

01:04:35the shoes somewhere,

01:04:36most likely to dry,

01:04:37since most boots

01:04:38are meant to be worn

01:04:39in the colder weather.

01:04:41Now,

01:04:41I've been guilty

01:04:42at least once

01:04:43of overdressing

01:04:44with a bunch of layers

01:04:45just so I won't need

01:04:46to jam everything

01:04:47in my check-in bag.

01:04:49But does it become

01:04:50a problem

01:04:51when you actually

01:04:51have to get seated?

01:04:53What do you do

01:04:53with your coat

01:04:54or your jacket?

01:04:55Well,

01:04:56have a closer look

01:04:57next time you board

01:04:58a plane

01:04:58on the seat

01:04:59in front of you.

01:05:00The hook

01:05:01that keeps the tray table

01:05:02upright

01:05:03can double

01:05:03as a jacket hook.

01:05:05As long as you

01:05:06don't need to have

01:05:06any meals

01:05:07while in the air,

01:05:08you're good to go.

01:05:10Now,

01:05:10most mascaras expire

01:05:12within 3-6 months,

01:05:13I'm told,

01:05:14depending on the manufacturer.

01:05:16But you can help

01:05:17speed up that process

01:05:18if you're not

01:05:19careful enough.

01:05:20Continuously pumping

01:05:21the mascara wand,

01:05:22trying to mix in

01:05:23the product,

01:05:24actually pushes

01:05:25more air into the tube.

01:05:26This can make it

01:05:27dry much faster

01:05:28and you evidently

01:05:30won't get the desired

01:05:31results with it

01:05:31anymore.

01:05:32There's an easy way

01:05:34to check if your

01:05:34mascara is still

01:05:35good enough to use.

01:05:37If you don't hear

01:05:38a popping noise

01:05:39when you take

01:05:39the brush out,

01:05:40you may very well

01:05:41need to go get

01:05:42yourself a new

01:05:43mascara tube.

01:05:45Now,

01:05:45I know we're

01:05:46living in the era

01:05:47of Bluetooth-connected

01:05:48devices,

01:05:49but for better

01:05:50quality sound,

01:05:51they still recommend

01:05:52using headphones

01:05:53that connect

01:05:54via audio jacks.

01:05:55Remember seeing

01:05:57black ridges

01:05:57on those jacks?

01:05:58They aren't there

01:05:59just to make them

01:06:00fit when you

01:06:01plug them into

01:06:01your phone or

01:06:02laptop.

01:06:03Made out of a

01:06:04special insulating

01:06:05material,

01:06:06these bands are

01:06:07meant to guard

01:06:07the wires when

01:06:08sound is being

01:06:09transmitted.

01:06:10Based on the

01:06:11number of bands,

01:06:12you can figure out

01:06:12which end goes

01:06:13where.

01:06:14Some empty space

01:06:15under noodles

01:06:16in a cup doesn't

01:06:17mean the company

01:06:18producing them wants

01:06:19to cheat you out

01:06:20of a full portion.

01:06:21No, no.

01:06:22It's a manner of

01:06:23keeping the noodles

01:06:24intact during

01:06:24their transportation.

01:06:26It also helps

01:06:27with the circulation

01:06:27of hot water

01:06:28that is poured

01:06:29over the products

01:06:30before you can

01:06:31enjoy them.

01:06:32The V-shaped

01:06:33neckline was

01:06:34initially designed

01:06:35to serve a bunch

01:06:36of objectives.

01:06:37First, as a way

01:06:38of prolonging the

01:06:39life of the

01:06:39garment that would

01:06:40maintain its shape

01:06:41over the years.

01:06:42It's also there

01:06:43to fit your head

01:06:44through the shirt

01:06:44in case it needs

01:06:45some stretching.

01:06:46This way, it

01:06:47ensures a snugger

01:06:48grip around the neck.

01:06:50Lastly, it helps

01:06:51absorb sweat in case

01:06:53you're wearing the shirt

01:06:54while exercising.

01:06:55Now, it's not

01:06:56necessarily a custom

01:06:57anymore, but you

01:06:58may have stumbled

01:06:59upon a dinner jacket

01:07:01with an additional

01:07:02mysterious pocket

01:07:03on the right side.

01:07:04Turns out, this pocket

01:07:06was used by men

01:07:07to easily reach

01:07:08their train tickets

01:07:09since most of them

01:07:10had to travel

01:07:11to work every day.

01:07:12It helped them

01:07:13keep their jacket

01:07:14buttoned up, but also

01:07:15benefited from the

01:07:16use of a pocket.

01:07:17Now, it's only added

01:07:18as a decoration,

01:07:19and it doesn't serve

01:07:21an actual purpose

01:07:22anymore.

01:07:23Speaking of things

01:07:24we don't use these

01:07:25days, or at least

01:07:26for their initial

01:07:27purpose, did you

01:07:28know Play-Doh was

01:07:29originally a cleaning

01:07:30product?

01:07:31In the 1920s, the

01:07:33market was in need

01:07:34of a product that

01:07:35could help them wipe

01:07:36the wallpapered areas

01:07:37around coal-burning

01:07:38furnaces.

01:07:39The recipe for what

01:07:41we now know as

01:07:42Play-Doh was thus

01:07:43invented.

01:07:44It was manufactured

01:07:45in white only, and

01:07:46was supposed to

01:07:47clean wallpaper by

01:07:48being rolled back and

01:07:49forth over the dirt.

01:07:51It was only later in

01:07:52the 1940s that new

01:07:54products for cleaning

01:07:55wallpaper were brought

01:07:56up, and Play-Doh was

01:07:58redirected toward

01:07:59another area of the

01:08:00market.

01:08:01Now, while I enjoy a

01:08:03nice piece of toast

01:08:04for breakfast, isn't

01:08:05it pesky to have to

01:08:06clean out the toaster?

01:08:08Well, not anymore,

01:08:09since I recently found

01:08:11out that toasters have

01:08:12a slide or a panel at

01:08:14the bottom that helps

01:08:15get rid of all those

01:08:16annoying breadcrumbs

01:08:17easily.

01:08:20Now, there used to be a

01:08:22time when you could

01:08:23only have access to

01:08:24video games by inserting

01:08:25cartridges in your

01:08:26console of choice.

01:08:28These tiny objects gave

01:08:29many doctors a lot of

01:08:31headaches.

01:08:32People soon started

01:08:33popping up in hospitals

01:08:34after swallowing small

01:08:36game cartridges,

01:08:37especially the younger

01:08:38generation.

01:08:39Nintendo, the company

01:08:41that manufactures the

01:08:42majority of these

01:08:43devices, had to come up

01:08:44with a creative solution

01:08:46to prevent these

01:08:47accidents.

01:08:47So, these days,

01:08:49Nintendo Switch

01:08:50cartridges are purposely

01:08:51coated with specific

01:08:52chemicals that can leave

01:08:54a really bad bitter

01:08:55taste in the mouth.

01:08:56Not that I'd, you know,

01:08:57recommend you ever try

01:08:59and taste for yourself.

01:09:00Hmm.
