00:00:00Road and construction workers are usually dressed in orange because the bright orange hue is visible even in bad weather.
00:00:07It's the most effective color to attract attention and alert people.
00:00:10No wonder lots of safety jackets and traffic cones are orange as well.
00:00:14The stop sign has an eight-sided shape to help drivers recognize it easily, even if they see it from
00:00:20the back.
00:00:20And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing the stop sign with any other
00:00:27at night.
00:00:28The rumble strips on the side of the road are placed there to alert drivers who doze off behind the
00:00:33wheel.
00:00:34When their tires move over these strips, the noise and vibration work like an alarm clock.
00:00:39There are magnetic locks on fuel hoses at gas stations.
00:00:43They come in handy if someone drives away with the gas nozzle still attached to their car.
00:00:48In this case, the lock detaches the hose automatically.
00:00:51Oh, that's embarrassing.
00:00:53Gasoline looks like a rainbow in a puddle because it can't mix with water.
00:00:56It forms a thin membrane over it.
00:00:59When light reflects from it and the water at the same time, you've got a rainbow.
00:01:05A triple handle on a jerry can is there to make it easier for two people to carry it and
00:01:10distribute fuel evenly.
00:01:12Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.
00:01:17The air passage will prevent it from pouring out, so no more fuel waste.
00:01:22Most gas cans have two holes with caps, a bigger and a smaller one.
00:01:27You're supposed to uncap the smaller hole before pouring gas inside the bigger one.
00:01:31It'll prevent the liquid from glugging and spilling all over your clothes and the ground.
00:01:37Another little thingy we often neglect is a point on an ointment cap.
00:01:40Most tubes are usually sealed with a plastic film or a foil, and opening it with your fingernails isn't the
00:01:46best idea.
00:01:47A point easily opens even the most safely sealed tube.
00:01:52You can use most screwdrivers together with a wrench to create more torque.
00:01:57Just place the wrench over the handle of the screwdriver.
00:02:00This way, you'll need to apply a lot less force than before.
00:02:04You'll also be able to get to hard-to-reach areas more easily.
00:02:08They install cameras in shops, banks, and hospitals to monitor everything.
00:02:13If something happens, you can call the police or rescuers.
00:02:17The camera really helps to solve a lot of problems.
00:02:19Why are there no cameras on planes?
00:02:23The crew keep order on the plane, but they won't be able to do anything if something serious happens.
00:02:28Besides, there's nowhere to run on the plane.
00:02:31During the flight, the cameras are useless, and after the flight, the words of the passengers work ideally instead of
00:02:38cameras.
00:02:39So, if cameras do no good, then why spend money on them?
00:02:43Water is great at cleaning stuff because it has triangular molecules.
00:02:47They're made of one oxygen and two hydrogen atoms.
00:02:50Um, H2O?
00:02:51Such molecules have slightly different charges on their opposite sides, pretty much like magnets.
00:02:57That's why water easily sticks to other molecules, including those that make up dirt.
00:03:02Lots of private houses have triangular-shaped roofs because this allows rain, snow, and fallen leaves to slide off the
00:03:08slope.
00:03:09If all this stuff piled up on top of your house, one day, your roof would collapse.
00:03:15When a storm is coming, clouds seem to turn dark, but it's just an illusion.
00:03:20Thin clouds on a sunny day let the light through easily.
00:03:23They also scatter all the colors of the light spectrum.
00:03:26This makes us perceive the clouds as white, but the thicker the clouds are and the more water droplets they
00:03:32contain,
00:03:33the less light they let through and the darker they look.
00:03:36A good doorknob is the one made of brass, bronze, or some copper alloys.
00:03:41Diamonds. These metals have an anti-germ effect.
00:03:45Bacteria spread way slower on them.
00:03:47They also get rid of germs pretty fast, within a couple of hours.
00:03:51Nope, it doesn't mean you don't have to wash your hands.
00:03:55Diamonds have such symmetrical shape to show you their brilliance.
00:03:58Initially, the gems aren't so beautiful.
00:04:01They go through several stages of cutting and then become pieces of elegance.
00:04:06Most of these stones have a round shape with slightly pointed corners.
00:04:10Diamonds shine the brightest in this shape.
00:04:14Why are there two holes in the socket?
00:04:16The left hole is neutral, the right hole is not, and the gap underneath is ground.
00:04:22Electricity needs to flow through the chain.
00:04:25The current flows from the hot slot, passes through your phone charger, for example, and then goes through the neutral
00:04:31hole.
00:04:32Ever wondered what that small pocket on your jeans is for?
00:04:35People used to wear watches on chains.
00:04:37That small pocket was meant for it.
00:04:40Now, almost no one wears such a watch, but the pocket remains.
00:04:44You can still keep something small in there, like a ring.
00:04:47In London, there are some poles that look like street lamps, but there are no bulbs.
00:04:52Well, their official name is stink pipes, and they're a thing of the past now, but they used to come
00:04:58in handy back in the 19th century.
00:05:00These hollow poles would vent away the air and explosive gases with bad smells to prevent, shall we say, unwanted
00:05:07consequences.
00:05:09Most kitchen shears have metal, plier-like teeth in the middle.
00:05:13Between the handle grips, they can help you crack nuts, crab shells, and other tough products.
00:05:18You can also open jars and bottles or remove herb stems with their help.
00:05:23Leather often looks dull to the eye because it's covered with itsy-bitsy scratches and scrapes.
00:05:29They scatter the light that hits the material.
00:05:31When you coat your shoes in a layer of wax, you fill these tiny crevices.
00:05:35The surface becomes smoother, and the rays of light bounce off it more evenly.
00:05:41That's why the leather looks shiny.
00:05:43Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
00:05:50Yellow and light green hues are the most popular because they don't prevent you from seeing the text after black
00:05:56-and-white photocopying.
00:05:58Photocopiers perceive yellow and light green marks as very pale and don't print them.
00:06:02They make magnets shaped as a horseshoe because this increases the magnetic force.
00:06:08Colors matter too.
00:06:09The blue part indicates the south pole.
00:06:12The red part, the north pole.
00:06:13The two poles work simultaneously and increase the attraction force.
00:06:18The dime-sized holes in elevator doors is actually a keyhole.
00:06:23If the doors get stuck, an operator can open them manually thanks to this hole.
00:06:28They'll just insert a special key.
00:06:31The tiny hole in the airplane window is there to balance air pressure.
00:06:35The window has three layers.
00:06:37The outer pane is extremely sturdy.
00:06:40It can withstand air pressure differences during take-off and landing.
00:06:44The inner pane, which is the closest to you, is made of cheaper materials.
00:06:48It prevents potential damage to the window.
00:06:50The hole itself is in the middle pane.
00:06:53It not only balances the pressure but also prevents the window from fogging.
00:06:59Escalator brushes are there for your safety.
00:07:01They don't allow you to come too close to the edge of the escalator.
00:07:05This way, your clothes won't end up between the steps.
00:07:08You see the sun as yellow or orange.
00:07:10Because the atmosphere of our planet scatters such colors as blue, green, and violet.
00:07:16This is also why the sun looks warmer at sunrise and sunset.
00:07:21Go shopping for some oranges and I'm sure you'll get them in a red mesh bag.
00:07:25You'll rarely see them lying around without one of those.
00:07:28It's pure marketing and that color isn't a random choice.
00:07:31When packed in a red mesh bag, oranges appear more orange, fresher, and more appealing to you.
00:07:38So, you're more likely to buy them, right?
00:07:41Lemons are usually sold in green mesh bags for a similar reason.
00:07:45If you pack them in red, they'll appear more orange.
00:07:48Green goes better with yellow and makes those lemons stand out.
00:07:52Mattress manufacturers make a limited number of different mattresses.
00:07:56And the only way to make them look different is to come up with a fancy stitching pattern.
00:08:01Two mattresses of two different companies might be the exact same quality but cost differently.
00:08:06Most people will never know it and will decide that different patterns mean something in terms of quality.
00:08:12So, when shopping, don't mind the pattern at all.
00:08:16Almost all hotels have white bedsheets.
00:08:18They choose this color specifically to show how high their standards of cleanliness are.
00:08:23The whiter and brighter the sheets are, the more luxurious the hotel seems.
00:08:27It's much easier to see dirt and stains on white linen.
00:08:31It's like proof that you've checked into a clean room.
00:08:34New iPhone models with large screens have a convenient option called reachability.
00:08:40Thanks to this function, you don't have to struggle to reach the top of the screen.
00:08:43This feature can be found in the phone's accessibility settings.
00:08:47It allows you to lower your screen down.
00:08:49The rumble strips on the side of the road are there to wake up sleepy drivers who doze off behind
00:08:54the wheel.
00:08:55When your tires drift off onto these strips, the noise and vibration work like an alarm clock.
00:09:01Most kitchen shears have metal, plier-like teeth in the middle.
00:09:04They allow you to use the device for multiple purposes.
00:09:07They're placed between the handle grips for you to crack nuts, crab shells, and whatnot.
00:09:12You can also open jars and bottles with their help.
00:09:15Some people even use these teeth to remove stems from herbs.
00:09:19If your audio jack has three rings, it means your device can produce stereo sound,
00:09:24and your earphones have the microphone function.
00:09:27The black grating on a microwave oven door is called a Faraday shield.
00:09:31It stops microwaves from getting away.
00:09:33If they do, your food won't cook properly.
00:09:36The digits on an egg can tell you a lot about the product.
00:09:40In many countries, there's a special labeling system.
00:09:43The first number indicates the method of production.
00:09:45The following two-letter code stands for the country where the egg was produced.
00:09:49And then you can find a registration number.
00:09:51It indicates the laying hen establishment.
00:09:54The first number in this code can vary from 0 to 3.
00:09:580 means it's an organic egg.
00:10:001. It's a free-range egg, which means it was produced by a hen that was allowed to wander around
00:10:05outdoors.
00:10:062 stands for an egg produced in a deep-litter indoor housing.
00:10:103. You're about to buy a cage farming egg.
00:10:14A black band that runs along the edges of your windshield is called the Frit.
00:10:18It's a baked-in ceramic paint that starts as solid black bands near the edge of the windshield.
00:10:23Then it dissolves into smaller dots.
00:10:26The Frit makes the glass rougher, and the adhesive sticks to it better.
00:10:30The Frit protects the urethane sealant.
00:10:32It's the substance that fixes the glass to the frame.
00:10:35It also prevents the sun's ultraviolet rays from melting the adhesive.
00:10:39As for the black dots, they help distribute the temperature in the car more evenly.
00:10:44They're aesthetically pleasing, too.
00:10:46Without them, the contrast between the glass and the dark band would be too obvious.
00:10:51If you see a pair of jeans with an extra loop, those are special jeans for cyclists.
00:10:56They're likely to belong to the commuter clothing line, and the loop's main purpose is to hold your bike lock.
00:11:03Many zipper sliders have outer rings, especially if such sliders are supposed to be used together.
00:11:09These rings are added so that you can connect the sliders with a lock and keep pickpockets away.
00:11:15Keyboards come with little legs.
00:11:17They were designed for you to be able to tilt your keyboard.
00:11:20This way, you can actually see which keys you're hitting.
00:11:23At the same time, a flat keyboard doesn't make your wrists so tired,
00:11:27and people who can type without looking at the keyboard don't need those legs whatsoever.
00:11:31An olive spoon is usually made of stainless steel, and has a small hole cut in its bowl-shaped head.
00:11:38The main purpose of this utensil is to lift olives, cherries, pickled garlic,
00:11:42and other products from liquid-filled jars, cans, or bowls.
00:11:46The hole in the middle allows you to drain the liquid gathering in the spoon fast and easily.
00:11:51What'll they think of next?
00:11:53Donuts are shaped like rings because, otherwise, they get overdone at the edges and remain uncooked and gooey inside.
00:12:00Make a hole in the center, and both the outsides and the insides will be cooked at the same time.
00:12:06Round-shaped donuts with no holes are usually filled with custard, cream, or jelly.
00:12:11Mmm!
00:12:12Such donuts don't have any corners, which means there are fewer weak spots for the filling to spurt out from.
00:12:17If you grab a full juice box a bit too firmly, you can get sticky liquid all over the place.
00:12:24To avoid such situations, flip up the tabs on the sides of the juice box.
00:12:28You can use them to hold your drink.
00:12:30Some cars have a tiny coffee cup sign on the dashboard.
00:12:34It's the vehicle's anti-drowsiness mechanism.
00:12:36Some manufacturers equip their cars with a drowsiness detection system.
00:12:41It analyzes the speed, wheel angle, and lane deviations, and figures out if it's time for the driver to take
00:12:47a break.
00:12:48If it is, the vehicle makes several audio signals, and the coffee cup sign starts to flash.
00:12:54Produce stickers on fruit and veggies you get at the supermarket are full of information.
00:12:59If there's a four-digit code on the sticker, the product was grown conventionally.
00:13:03In most cases, it also means that pesticides were used in the process.
00:13:07If the product is organic, its sticker has five digits, and the first one is nine.
00:13:13Genetically modified products also have a five-digit code, but the first number is eight.
00:13:19Sugar used to be sold in sugar loaves.
00:13:22Those were tall, hard cones.
00:13:24At those times, to get sugar ready for tea, people had to use special hammers to break a loaf apart
00:13:30first.
00:13:30After that, they cut the sugar into smaller and more nicely shaped lumps.
00:13:35Only in the middle of the 19th century, people invented the first press that cut sugar into cubes.
00:13:41This way, the product was easier to store and transport.
00:13:44A little hole in the end of your wrench can provide your screwdriver with some extra torque.
00:13:49Just slide the end with the hole over the screwdriver.
00:13:52You can also use this method when the angle is awkward.
00:13:55While driving, when it's already dark, you might get blinded by the headlights of the car moving behind yours.
00:14:01If you have a manual rearview mirror, find a tab at the bottom and flip it.
00:14:06The mirror has a reflective material behind its glass.
00:14:09By flipping the tab, you change the angle of this material, dimming the lights in the mirror.
00:14:15Most ice cream scoopers come in different colors.
00:14:18It has nothing to do with aesthetics.
00:14:19The color indicates the size of the scoop.
00:14:22This way, you can easily figure out how many scoops you'll need to fill 32 ounces.
00:14:27Wow, a 32-ounce sundae!
00:14:29Sign me up!
00:14:31Some caps on small tubes are hollow on top and have a little spike inside.
00:14:35Its purpose is to break the foil sticker sealing the tube.
00:14:39The neck fits right in this hole, and the spike is designed to break the seal.
00:14:43This way, you don't need to tear the tiny foil seal off with your fingers.
00:14:47The letter R in a circle on the product's packaging means that the trademark is officially registered.
00:14:54Once it's done, the trademark's owner has the right to place this letter on all their products.
00:14:59They can also sue anyone who tries to use their trademark.
00:15:02A gas pump usually has a small metal latch or hook on its handle.
00:15:07That's a trigger lock.
00:15:08You can use it to lock the handle in the open position.
00:15:11Then the gas will keep pumping even if you walk away.
00:15:15Coins used to be shaped randomly or have no shape whatsoever in the past.
00:15:20Dishonest people used it to their advantage.
00:15:22They stole valuable metals the coins were made of by chipping their corners off.
00:15:27It was illegal, and to prevent this kind of fraud, round coins were invented.
00:15:31After that, it became easy to instantly notice when a coin had been fiddled with.
00:15:37Those two holes in a lollipop stick are there to hold the candy in place.
00:15:41When the stick is dipped in hot liquid syrup, it flows into the holes and solidifies.
00:15:46Now, your suite is there to stay.
00:15:49Fabric squares that come with clothes are for you to try out your cleaning products on them first.
00:15:54This way, you won't ruin the entire item once you decide to wash it.
00:15:57The holes in the bottoms of earphones allow air to circulate up and through the speakers.
00:16:03It helps to increase low frequencies, making the bass sound deeper.
00:16:07The sound quality also becomes much better.
00:16:09Don't I sound better?
00:16:12You can adjust your stapler so that it staples documents together only temporarily.
00:16:16It's done by rotating the crimp area.
00:16:19Most staplers have two options for stapling.
00:16:22One is standard, but the other side bends staples away from the center.
00:16:26Later, when you don't need them anymore, you can easily remove them by hand.
00:16:30If you store peanut butter jars upside down, the oil will move to the bottom and all the solids will
00:16:37be on top.
00:16:38Hey, don't laugh.
00:16:39That matters to some people.
00:16:40You don't want to get caught with your peanut butter down.
00:16:44Now, if you're as watchful as I am, you've probably noticed those zigzag patterns on the edges of some packages,
00:16:51like bags of chips or chocolate bars.
00:16:53It's clear that they're there to make it easier for you to tear the plastic.
00:16:57But why does it tear so easily?
00:17:00Now, plastic is made of long molecules called polymers.
00:17:04You can compare it with a fabric made of long threads.
00:17:07But the scale is much smaller, and these strands aren't actually woven together.
00:17:12What ridges do is remove the support of the surrounding polymer fibers.
00:17:16When the edge is flat, the molecules are surrounded and kind of protected by their mates.
00:17:21But if the edge is uneven, molecules on the peaks of the ridges are much more exposed to mechanical damage.
00:17:29Plus, such an uneven edge allows you to apply more force to a specific point, the groove.
00:17:34And once that point fails, the groove moves to the next point, causing more tearing.
00:17:40And this process continues until you stop applying the force or until you're done tearing the packaging apart.
00:17:47But this isn't the only packaging secret.
00:17:50I'm about to reveal the most unexpected packaging facts.
00:17:54Now, is this what the future of packaging looks like?
00:17:57A Swiss company has invented a magic juice box.
00:18:00It's made of agar-agar seaweed gel and water.
00:18:04It can only contain short-term smoothies and juices.
00:18:07The box also withers at the same rate you consume the product inside.
00:18:12Wow! Doesn't it sound like the future is here?
00:18:15That overwhelming smell of coffee that literally hits you once you open a jar with instant coffee?
00:18:21This scent is actually just a coffee aroma sprayed onto the lid.
00:18:25It's done to provide you with the enticing smell of freshly ground coffee.
00:18:30One of Korea's leading manufacturers of instant noodles has come up with innovative packaging for their production.
00:18:37It can be safely used in microwaves.
00:18:39The company claims that some additional material used in this packaging can remain intact without melting, even at high temperatures.
00:18:47Well, it'll definitely make the process of heating up your lunch much faster.
00:18:52Now, almost all food we consume has an expiration date.
00:18:57But this rule doesn't apply to water.
00:18:59Hmm, but how come there's an expiration date on every water bottle?
00:19:04There's no paradox here.
00:19:05This expiration date refers to the bottle, not the water inside.
00:19:10They say that regardless of the brand, all chips have a best before date that ends on a Saturday.
00:19:17It's because a production week starts on a Sunday and correspondingly ends on a Saturday.
00:19:23Well, I've checked my stash and it seems to be true.
00:19:27Go look at yours and write in the comments what you found out.
00:19:30Bubble wrap was originally designed to serve as textured wallpaper.
00:19:35It was invented in 1957 by engineers Mark Chavons and Alfred Fielding in New Jersey.
00:19:41They sealed together two shower curtains trapping inside a smattering of air bubbles and wanted to sell the resulting product
00:19:49as an innovative kind of wallpaper.
00:19:51Unfortunately, the product turned out to be a failure as wallpaper.
00:19:55Then the inventor started selling it as greenhouse insulation.
00:19:59But it wasn't until 1961 that the material's protective qualities were discovered.
00:20:05And the first client that used bubble wrap as a packaging material was IBM.
00:20:10This company used it to protect its big IBM 1401 mainframe computer during shipping.
00:20:17Now, people love personalized products.
00:20:20According to researchers, a whopping 52% of online customers are more willing to repeat their purchases from a company
00:20:27when they get personalized shipping boxes.
00:20:30If you've ever seen someone unboxing Apple products, you probably noticed that the company used very laconic packaging.
00:20:37This probably made you think that they put no effort into it.
00:20:41But that's not true.
00:20:42To achieve such a level of perfect simplicity, Apple has created a real culture around its packaging.
00:20:49The company's headquarters even have a special place where they come up with packaging designs for new products.
00:20:55The Egg Carton was designed in 1911 by newspaper editor Joseph Coyle from British Columbia.
00:21:02The main goal of this invention was to resolve a dispute between a local farmer and a hotel owner who
00:21:09kept complaining that the farmer's eggs were delivered broken.
00:21:12So, necessity is the mother of invention.
00:21:16Nike has created a shoe box made completely out of recycled trash materials, mainly drink containers.
00:21:23This box also allows its owner to wear it as a backpack.
00:21:27Now, paper packaging for food goes all the way back to China, to the 2nd century BCE.
00:21:34At that time, food was often wrapped in thin sheets of mulberry bark.
00:21:38And later, the idea spread all over the world.
00:21:42And in 1879, one accident literally changed history.
00:21:47A worker from a paper bag factory in Brooklyn set the machine he used to the wrong settings.
00:21:52And instead of creasing small bags, it cut through them.
00:21:57When the owner of the factory readjusted the settings on the machine, he realized that it could cut and crease
00:22:03at the same time.
00:22:04This led to the appearance of mass-produced paperboard boxes.
00:22:09Now, researchers have found out that the process used during the manufacturing of cardboard boxes can ward off germs.
00:22:15Hear me out.
00:22:17To make cardboard, they shape layers of paper and bond them at a temperature of up to 200 degrees Fahrenheit.
00:22:23That's hotter than most harmful bacteria can withstand.
00:22:27That's why cardboard boxes are a rather safe way to package foods.
00:22:31After all, they come out of the manufacturing process sanitized, even when they're made of recycled materials.
00:22:38That little open jar icon on cosmetic packaging is the PAO, period after opening symbol.
00:22:46It informs consumers about the period of time a product may be used after the package is unsealed.
00:22:52The symbol, featuring a number followed by the letter M for months, can be seen on almost all cosmetic products.
00:22:59Some plastic milk containers have dents on their sides.
00:23:03These dents serve several purposes.
00:23:05For one thing, when the milk spoils, this process usually causes swelling and high-pressure buildup inside the container.
00:23:13That's when the dent comes in handy.
00:23:15It pops out and doesn't let the jug blow up.
00:23:18Plus, if you decide to freeze the milk, it will expand like any other liquid.
00:23:23And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
00:23:30Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
00:23:36That's because soda contains carbon dioxide.
00:23:39It's a gas that can expand once the bottle is heated.
00:23:42If there's no gap in the bottle, it can break because of the pressure building inside.
00:23:48Also, when you open your drink, the gases go out in the form of bubbles.
00:23:52And the drink is likely to overflow.
00:23:54The gap helps with this problem, too.
00:23:57Now, about those horizontal lines on plastic bottles.
00:24:01They help hold bottles up.
00:24:03Some bottles are produced from soft plastic.
00:24:05Without the lines, they wouldn't keep their shape.
00:24:08Instead, they would twist easily or even break.
00:24:12Number 57 on a Heinz ketchup bottle has nothing to do with the product label.
00:24:17The truth is that the place with the numbers is the very sweet spot you should tap to get the
00:24:23ketchup flowing.
00:24:23So, stop smacking the bottom of your sauce bottle and tap the 57.
00:24:29By the way, if you've been wondering why the number is exactly 57, not 34 or 89,
00:24:36this comes from the historical advertising slogan, 57 Variety,
00:24:40created by the Heinz Company located in Pittsburgh, USA.
00:24:44This advertising campaign told customers about the numerous products manufactured by the company.
00:24:50Now, at first sight, everything is obvious about plastic lids on disposable cups.
00:24:55To keep your beverage inside, right?
00:24:58But that's not all they're capable of.
00:25:00As soon as you find a cozy spot and get ready to sip on your drink,
00:25:05you can use the lid as a coaster.
00:25:07If you look carefully, you'll notice special ridges that hug the bottom of your cup snugly.
00:25:12It's a snuggly hug.
00:25:14The size of each lid fits the bottom of the corresponding cup.
00:25:20And the soft round part under a soda bottle cap keeps the carbonation from escaping.
00:25:26Without it, your pop would go flat in no time, probably even before you buy it.
00:25:37So get this, an extra hole at the upper part of the sink has multiple hidden functions.
00:25:42First, in case someone forgets to close the tap, the water won't overflow and the bathroom won't get flooded.
00:25:48Second, thanks to that hole, the water drains faster and it gives an escape for the air, helping the water
00:25:53flow down.
00:25:55Those two holes on a side of any Converse shoe are not only to let the stinky air out.
00:26:01Sure, breathability is important for any athlete.
00:26:03The second reason is that athletes lace through those holes to get a better grip.
00:26:10Donuts have a hole in the middle and it doesn't stand for O in donut.
00:26:14It's not designed for an easier grip either, though it can be quite convenient.
00:26:18It's actually made this way for mass baking, so that they can cook all the way through evenly.
00:26:25Baby carrots are tiny and, unlike regular carrots, wet.
00:26:29Baby carrots aren't some special sort of carrots.
00:26:31They're actually made of regular carrots by cutting off the skin and outer layers and then polishing them to look
00:26:37that pretty.
00:26:38The problem is that they can't retain moisture.
00:26:41A regular carrot retains some water inside because of the layers that locks it in.
00:26:45Once they're chopped out, baby carrots can dry out easily, so they usually sell them in bags with some water
00:26:51inside.
00:26:53Toy stores are filled with Beanie Baby plush toys, and a detail that is even more iconic than their huge
00:26:58eyes is their tags, saying T.Y.
00:27:02That's a small manufacturing company not so many people have heard of.
00:27:05Beanie Babies appeared in 1993, and they went insanely popular.
00:27:10T.Y. is the name of the company, but it's not an abbreviation.
00:27:13It's the actual name of the company's founder, H. Ty Warner.
00:27:19Most metallic zippers have a hidden lock inside them to save you from awkward situations, such as an undone fly.
00:27:26Oh boy.
00:27:27Don't leave the zipper handle in an upward position.
00:27:30When you pull it downwards, it automatically locks.
00:27:32It's all thanks to those tiny grooves hidden underneath the handle.
00:27:38Almost any public toilet has a large gap between the floor and the door.
00:27:42The reason for such a zero-privacy thing is to actually minimize the level of privacy and comfort,
00:27:48so that people wouldn't stay there long and there'd be no lines.
00:27:51It's also easier to clean, and safer if some emergency occurs.
00:27:58Headrests in a car are about comfort, and detachable headrests are about safety.
00:28:03If you pull the headrest out of a seat, you'll see two bars, which are quite sturdy.
00:28:08If you ever get locked or trapped in a car, you can get out of there smashing the window with
00:28:13these bars.
00:28:17Many cups and mugs have little grooves on the bottom on purpose.
00:28:20They're designed for dishwashing machines.
00:28:22The grooves let the water flow and not spill over your feet when you take the cup out.
00:28:27Also, those grooves let the air flow so the cup doesn't crack even if the tea is scalding.
00:28:35Almost all measuring tapes have a metal tip with a small slot on the end.
00:28:39You can use this slot to hang the tape on a nail or a screw to make measurements without anyone's
00:28:44help.
00:28:46Sometimes, this tip has a row of sharp points along the edge on one side.
00:28:50That comes in handy when you want to leave a mark without using a pencil.
00:28:55Doorknobs are usually made of brass, bronze, and some other copper alloys for a reason.
00:29:00They have an antibacterial effect, so they stop microbes from spreading.
00:29:05They get rid of a range of harmful germs pretty fast within a couple of hours.
00:29:10But don't forget to wash your hands anyway.
00:29:14Grocery carts have loops for a reason.
00:29:16You don't want to put your jacket in a cart next to potatoes and onions.
00:29:20Hang it on a loop.
00:29:22This little hook-like thing is there to help you better organize the space in your cart.
00:29:26The carts also have a super handy grid.
00:29:29Whenever the cart's full, you just need to lift the grid and attach the shopping basket for extra purchases.
00:29:34Placing it in between the horizontal bar above the wheels and the hooks the grid has.
00:29:41A point in an ointment cap is there for a reason too.
00:29:45Most tubes are usually sealed with foil, and it's better to avoid opening it with fingers unless you're ready to
00:29:50say goodbye to your nails.
00:29:52A point easily opens even the most safely sealed tube.
00:29:58Silica gel can often be found in different things you buy, like bags, shoes, and many others.
00:30:03Don't throw it away.
00:30:05It's meant to absorb excess moisture.
00:30:07So anytime your shoes are a bit wet, just throw in a packet with silica gel.
00:30:13People used to co-live with rats, and these guys like gnawing on everything they see in their way, including
00:30:19paper.
00:30:20Still, rats weren't able to chew more than the space left on the margins.
00:30:27That black grate on a microwave isn't just some fancy decoration.
00:30:30It's called a Faraday shield, and it prevents the rays from escaping the microwave.
00:30:35It also speeds up the heating, so you can enjoy yesterday's leftovers faster.
00:30:40It may also block phone signals.
00:30:42So if you're tired of numerous calls, just put the phone into a microwave.
00:30:46But don't turn it on.
00:30:50All Tic Tac containers are designed to dispense one Tic Tac every time you open it.
00:30:55The lid has the same shape as the candy.
00:30:58Turn the container upside down, gently shake it, and open it slowly.
00:31:01You'll notice only one candy stuck between those lid grooves.
00:31:05So if you just open the container and shake it until five or even more candies fall into your mouth,
00:31:10it means you've been eating Tic Tacs wrong all this time.
00:31:17Those little holes in the airplane windows are designed to control the cabin pressure.
00:31:21They also protect the windows from fogging up as the temperatures drop and rise.
00:31:25By the way, the airplane window is round for a reason.
00:31:28This way, pressure is evenly distributed so it doesn't get deformed.
00:31:35Blue bristles on a toothbrush are actually an indicator that it's just about time to change the brush.
00:31:40As the bristles get in contact with water, the blue, or whatever other, pigment fades away.
00:31:45So the more you use it, the duller the color becomes.
00:31:50A triple handle on a jerry can is there to make it easier for two people to carry it and
00:31:54distribute the fuel evenly.
00:31:56Gas cans often have a second hole that actually needs to be unkept too before you pour the gas.
00:32:01The air passage will prevent it from pouring out, so no more fuel waste.
00:32:07Jeans first appeared in 1873.
00:32:10They were invented by Jacob Davis and Levi Strauss.
00:32:14Davis was a tailor who was producing covers and tents, and Strauss was a businessman who, among other things, was
00:32:21selling cloth.
00:32:22The first jeans were made by Davis from denim, the fabric he bought from Levi Strauss & Co.
00:32:29Together, they patented the design.
00:32:31Blue was a standard color for denim that was dyed using an indigo dye.
00:32:36The blue color is a tradition that is still often followed today to replicate the original look of a pair
00:32:41of jeans.
00:32:41Jeans also have metal rivets, and they've been there from the very beginning.
00:32:46Jacob Davis, the man who made the first pair of jeans, added copper rivets to spots where pants were more
00:32:52likely to rip, flies, and pockets to make them stronger.
00:32:55Today, they have more of a decorative purpose since they're distinctive and traditional for jeans.
00:33:02Another special thing about jeans is those tiny pockets they have that seemingly serve no purpose.
00:33:08Well, maybe it's true now, but years ago, when many cowboys were wearing jeans, the pocket was made specifically to
00:33:14keep a pocket watch there.
00:33:16Also, back then, a pair of jeans had just four pockets.
00:33:19That tiny pocket, the watch pocket, two big pockets in front, and just one pocket on the back.
00:33:27Many zippers have the letters YKK engraved on them.
00:33:31It's an abbreviation that stands for the name of the company that can be translated as Yoshida Manufacturing Shareholding Company.
00:33:39This Japanese company is the largest zipper manufacturer in the world, so they put their initials on all the zippers
00:33:45they produce.
00:33:45That's around half of the zippers in the world.
00:33:48And that's why you see their zippers more often than any other zippers.
00:33:54Those little white golf balls have dimples all over them.
00:33:57It turns out they aren't there just randomly.
00:33:59At first, golfers were playing with a smooth ball.
00:34:02With time, the ball would get all punched and damaged, but also, it would start to travel way further.
00:34:08The reason here is aerodynamics.
00:34:10Dimples allow the air to flow more smoothly around the ball, taking it further.
00:34:14So the idea was adopted, and the balls got their dimples all around, allowing them to travel longer distances.
00:34:22From the iconic golden fries to a broken ice cream machine,
00:34:26here are 10 fast food secrets that the fast food industry doesn't really want you to know.
00:34:31Ah, chicken nuggets.
00:34:33Those golden crispy bites you can get from fast food chains.
00:34:37They're even on the menu of school lunches.
00:34:39What if I tell you that they aren't actually made entirely out of chicken?
00:34:43Researchers took chicken nugget samples from unnamed fast food chains and analyzed them.
00:34:49They said that one sample, for instance, contained only 40% and another 50% of meat.
00:34:55The rest?
00:34:56Well, you're eating mouthfuls of things like fat, connective tissue, and bone spicules.
00:35:02Many fast food companies grind the meat with that stuff.
00:35:05They make mechanically formed orbs of chicken parts.
00:35:08Why?
00:35:09Perhaps it's because this method is cheaper and more profitable.
00:35:13Millions of restaurants worldwide have chicken nuggets on their menu.
00:35:16So, scientifically, it's not fair to say all nuggets are made this way.
00:35:20But a lot of studies imply so.
00:35:23The more the meat is processed, the more you lose the good stuff, like vitamin B6 and B12.
00:35:29The bitter truth is that companies add stuff, such as sodium, to the mixed paste.
00:35:35Sodium is added to get a better flavor.
00:35:37It's one of the ingredients that makes nuggets so yummy.
00:35:40Our bodies need sodium, but not too much of it.
00:35:44Unfortunately, most junk food contains more than our bodies can handle.
00:35:48So, it might be a safe option to avoid eating these sorts of foods frequently.
00:35:53Chains dip their nuggets into tempura batter and fry them in hydrogenated oil.
00:35:58That's also not a green light regarding health, but this is how they catch the golden tint.
00:36:04They put additional stuff in nuggets.
00:36:06What about grilled chicken?
00:36:08In recent years, we've seen brands highlighting grilled chicken as a healthier option.
00:36:13Research has been done about grilled chicken, too.
00:36:15And the same approach is applied here.
00:36:18Take chicken samples from iconic fast food companies and send those to labs for analysis.
00:36:23The results show that companies are misleading people by advertising these products by labeling
00:36:30them as healthy, natural, and 100% chicken breast.
00:36:34In reality, a couple of things are added to the meat to make it tender and juicy.
00:36:39Plus, these additives make it easier to cook the meat, freeze, and transport it, and reheat
00:36:44it later without losing too much moisture.
00:36:47The drawback of all these additives is that they affect the nutritional value of the chicken
00:36:52breast.
00:36:53These ingredients aren't the healthiest for us.
00:36:55We should especially watch out for three things.
00:36:58The first one is, again, sodium.
00:37:00Fast food samples had 7 to 10 times more sodium than home-cooked chicken breast.
00:37:06Imagine you have a cheeseburger, but you say no to yourself and try to pick a less harmful
00:37:10menu item.
00:37:11Yet, some chicken sandwiches have the same amount or even more sodium than a cheeseburger with
00:37:17medium fries.
00:37:18The second thing you need to watch out for is phosphate additives.
00:37:22These additives allow the protein to conjoin more water.
00:37:25This means the white meat in the sandwich will appear juicier to you.
00:37:30Any word you see in the ingredients section that contains FOSS is a phosphate additive, so
00:37:36it's best to avoid them.
00:37:38The last thing you should avoid is sugars and starches.
00:37:41Not just in grilled chicken, but pretty much in all fast food products.
00:37:45Oh, that's hard to digest, I admit.
00:37:47Cornstarch, sugar, malt, they come with grilled chicken breast.
00:37:51Buns and even some fries have sugar too.
00:37:55Everywhere I look, it's sugar.
00:37:56You see, home-cooked chicken has zero grams of carbs, but the study samples had added sugar
00:38:02and up to 10% of the calories in the chicken breast comes from there.
00:38:06So what's the moral of this story?
00:38:08If you're a health-conscious diner, you should maybe go for other options.
00:38:13There are secret recipes from companies like KFC and Coca-Cola.
00:38:18No company wants to share the ingredients that make their food irresistible, but with a little
00:38:23research, you can decipher many things.
00:38:25You want to know the secret of McDonald's fries?
00:38:28It's written on their website.
00:38:30They add beef flavoring to the frying oil.
00:38:33This may sound weird, but apparently, that's a known practice amongst chefs and restaurants.
00:38:38Duck fat has also been used as a flavor, for example, in high-end restaurants.
00:38:44I'm a fries lover, so I added another fact about fries.
00:38:48Sadly, they're even saltier than you think.
00:38:50Experts suggest that a grown-up should consume at most 2,300 milligrams of sodium daily.
00:38:57Guess the McD's large fries sodium number?
00:39:00At least 400 milligrams.
00:39:03Classic fries from Burger King have 732 milligrams, and Five Guys take the level even higher with
00:39:11962 milligrams of sodium.
00:39:13Next time, maybe you can ask workers to go easy on the salt as a solution.
00:39:19Picture this.
00:39:20You're in a hurry, but your tummy says,
00:39:22Feed me, or I'll affect your mood and make life miserable for you.
00:39:25For a quick snack, you enter a fast-food chain restaurant.
00:39:29You order your favorite burger.
00:39:31It looks and smells as if it's just been taken from the grill and served.
00:39:35Nope.
00:39:36They have different types of grills designed for this that can cook meat super quickly.
00:39:40Sorry to bear the bad news, but those perfect grill marks on your burger aren't real tools.
00:39:46The factory adds them.
00:39:48If you want to know how clean an eatery is, look under the ice chute of the soda machine in
00:39:53places where you can get your own drink.
00:39:55There you go, inspector.
00:39:56You solved the case.
00:39:58Various studies say that if such machines aren't cleaned correctly, dirty, contaminated ice can lead to some health problems.
00:40:05There could be mold or bacteria there.
00:40:08Ew.
00:40:09The process of cleaning ice machines isn't easy.
00:40:12The same thing applies to ice cream machines, too.
00:40:15Rumor has it that those ice cream machines aren't out of order.
00:40:18Employers just cannot find time to clean them properly.
00:40:21Now, what's the best time to get a good and fresh meal?
00:40:25Here are two opinions, and they both have solid reasonings.
00:40:28The first team recommends avoiding ordering grilled food in chains from 7 to after midnight.
00:40:34Many former employees say that sometimes they had taquitos or hot dogs prepared at around 4 or 5 a.m.,
00:40:41but kept waiting to serve them till around midnight.
00:40:44That's not healthy.
00:40:46The other team says you should order between 11 a.m. and 1 p.m., or between 6 p.m.
00:40:51and 8 p.m. to get the freshest meal.
00:40:54Since it's going to be around lunch and dinner time, there'll be circulation and you can get decent food.
00:41:01Fast food companies have marketing, design, and psychological tricks to lure you in and make you order.
00:41:07Yet, they don't want you to stay inside for too long.
00:41:10If you were dining in mood lighting, you know under dim lamps and candlelight, you would take your time to
00:41:15eat.
00:41:16As the name suggests, you should be fast like your food in chain restaurants.
00:41:20They have fluorescence, and they're in full light.
00:41:24Similarly, the floors and tables have reflective surfaces that make food look nice and bright.
00:41:30Plus, music is usually fast and loud.
00:41:33It's done to prevent you from spending hours there.
00:41:36Yet, they want you to take advantage of the first 20 minutes after your purchase.
00:41:41The faster you eat, the longer it will take you to feel full.
00:41:45Scientists say it takes about 20 minutes for our stomachs to inform our brain,
00:41:49OK, now I'm full.
00:41:52It's a good idea to eat in a clean area, but most of these companies are using cleaning products that
00:41:57have super strong chemicals.
00:42:00Assume that the staff clean the place at the end of their shift.
00:42:03They wipe down the soda machine and grill surface, and then you show up early the next day.
00:42:08You may get some of that chemical residue on your food compared to other customers visiting the place later in
00:42:14the day.
00:42:16The vegan patty may not be 100% vegan.
00:42:20I'm talking about the grill, not the meat itself.
00:42:22In most of the chains, vegan burgers are cooked on the same grill as meat burgers.
00:42:28Do you have fast food chain secrets you want to share?
00:42:31Tell them to fellow brightsiders in the comments.
00:42:37Bet you've never heard of corrugation.
00:42:40It's a system that may lie hidden in your pantry right now.
00:42:45Ever notice those bumps on food cans?
00:42:48That's exactly what they're called.
00:42:50And they're not just for aesthetics.
00:42:52First off, they make the can extra strong.
00:42:55That's because they can help it from cracking during the manufacturing process.
00:43:00Plus, these corrugations come in handy during delivery, acting like a shield to make sure there's no spillage.
00:43:08They're also useful in the long run because they help keep the cans in their original shape.
00:43:13Even when things get too hot or too cold, these corrugations let them breathe a bit.
00:43:18They expand and contract without breaking the metal.
00:43:21You may not notice any cracks on regular cans, but even the tiniest of openings can leave a way for
00:43:28nasty bacteria to get in contact with the food.
00:43:31Not to mention, they create this little air gap.
00:43:34So when you pop the can open, everything slides out smoothly, without you having to put in that much effort.
00:43:41You know what also doesn't require much effort?
00:43:44Hitting that subscribe button and liking this video.
00:43:50You know there's a plant out there that's so eager to reach the sun, you can hear it grow?
00:43:56Rhubarb, just before it's picked from the fields, soaks up all the sun rays it can get to make glucose.
00:44:02After this sunbathing session, it gets transported to dark sheds.
00:44:07Inside, it keeps on growing and uses the stored glucose as fuel.
00:44:12Nothing out of the ordinary so far, but in that dark, cozy, and warm place, rhubarb starts acting weird.
00:44:20That environment pushes the plant to stretch itself out in hopes it will find sun rays again.
00:44:27It happens so fast that you can actually hear the buds and stalks making noise as they pop open.
00:44:35To make sure this process goes smoothly, there's no light allowed.
00:44:40If light hits the rhubarb at this point, it will start photosynthesizing again and go bitter.
00:44:49Speaking of everyday groceries, you might have noticed that veggie bags come with some green stripes.
00:44:55Know that it's a sneaky optical trick.
00:44:58Those stripes fool our eyes into believing the veggies look way greener than they are.
00:45:03And it's not just veggies that get this special packaging.
00:45:07Oranges are often sold in red mesh bags for the same reason.
00:45:12Lemons? They go for yellow or green bags for that same pop of color.
00:45:18If your cooking skills aren't that good and you're just afraid you're going to mess up dinner yet again, stick
00:45:24to mushrooms.
00:45:25That's because they're almost impossible to overcook.
00:45:28Unlike other vegetables that turn into mush when overcooked, mushrooms are way more resistant.
00:45:35They've got this interesting substance called chitin, a molecular structure that works like an armor.
00:45:42So you can cook them forever, they won't burn.
00:45:48Donuts don't have holes in them because it's easier for you to pick them up.
00:45:52If you've ever tried to make them at home, you might have noticed that when you fry the dough, the
00:45:57outside gets done quickly, thanks to the hot oil.
00:46:00If you want the inside to look just as good, you have to keep it in the oil way longer.
00:46:05But then, the outside would get too brown.
00:46:09Thanks to that middle hole, the heat gets to both sides equally, cooking up a flawless donut.
00:46:17Here's how that small piece of paper makes it into your fortune cookie.
00:46:21First, they bake these cookies flat like pancakes.
00:46:25Then, while they're still warm and bendy, they sneak in those tiny messages.
00:46:29As the cookies cool down, they toughen up and keep their shape, trapping the fortune inside like a tasty time
00:46:36capsule.
00:46:37One legend has it that these Asian treats were initially intended to help people send all sorts of secret messages
00:46:44without causing any suspicion.
00:46:47Here's a little tip for whenever you're buying lunch at a fast food place.
00:46:51Skip the word extra when you're ordering.
00:46:54The moment you speak that term, you're tempting the employees to charge more.
00:46:58Instead, go for something like, a little more please, when you're getting a special burrito bowl.
00:47:07According to a UK study, cheese is the most stolen of foods worldwide.
00:47:12It's estimated that around 4% of all cheese just vanishes from stores.
00:47:18And no, it's not mice doing the stealing, it's people.
00:47:22Why?
00:47:22Because cheese is becoming more and more valuable.
00:47:25The price of cheese is constantly going up.
00:47:28And sneaky thieves are trying to make easy money by simply taking it from the racks.
00:47:33It's not just cheese, though.
00:47:35Other interesting items on the thieving list include fresh meat, chocolate, and seafood.
00:47:43Ferrera.
00:47:44The company behind those luscious jars of Nutella needs about 25% of the world's hazelnuts every year.
00:47:52So, if you think about it, one in four hazelnuts ends up in a chocolatey jar.
00:47:57The manufacturers get the nuts from Turkey, Italy, and Chile, making sure they get them delivered from both the northern
00:48:04and southern hemispheres to keep things fresh.
00:48:07Nutella's impact on the economy is even bigger than you'd imagine.
00:48:10Because of this demand, the price of hazelnuts went through the roof.
00:48:16In 2014, a frost hit Turkey's hazelnuts.
00:48:19Supply got halved, and prices were even higher.
00:48:23Now, even places like New Jersey are trying to grow those Nutella-worthy nuts.
00:48:32When you imagine someone trying to sneak something into space, your first thought wouldn't be a sandwich.
00:48:38But back in 1965, during a Gemini mission, astronaut John Young brought a corned beef sandwich on board, going against
00:48:47NASA rules.
00:48:48He hid it in his spacesuit pocket before blast-off.
00:48:51About two hours into the five-hour trip, he went to the mission commander and offered him this unlawful treat.
00:48:58The commander, being a good sport, took it, and they shared a quick, savory moment.
00:49:03He even put the unfinished sandwich in his own spacesuit pocket to avoid crumbs making a mess of the spacecraft.
00:49:10Meanwhile, the official NASA-approved food was waiting patiently in a box nearby.
00:49:18Surely, radishes aren't your first pick when it comes to salad ingredients, but they have quite an interesting history, too.
00:49:24These mustard, broccoli, cabbage, and cauliflower cousins have been grown and eaten for longer than you'd imagine,
00:49:32even before the Romans were famous in ancient Egyptian times.
00:49:37In fact, radishes were used as currency for the people who built the pyramids, alongside onions and garlic.
00:49:46You'd think that English are champions when it comes to drinking tea, but you'd be wrong.
00:49:52Turkey is, in fact, the tea capital of the world.
00:49:55Every Turk drinks an average of 1,300 cups of tea each year.
00:50:00On a regular day, they're sipping on three to five cups, but when winter hits, they can reach ten cups
00:50:07a day.
00:50:08Locals claim tea is like a social custom for them.
00:50:11It's more than just a hot beverage.
00:50:13It's an excuse to sit down, enjoy the atmosphere, and connect with loved ones.
00:50:18When it comes to types, black tea is preferred.
00:50:21There might be a magical drink hidden in your fridge.
00:50:25It's tonic water, and it might be able to glow in the dark.
00:50:29If you're curious, test it out with some ultraviolet light.
00:50:33The secret behind this glow is pretty simple.
00:50:35Tonic water has quinine, a chemical that lights up under certain conditions.
00:50:42Quinine was used back in the day to treat certain health problems.
00:50:45The stuff was so bitter that some people started mixing it with sugar and soda water.
00:50:50In simple terms, things glow because they absorb light energy,
00:50:55gets all excited, and then releases it as visible light.
00:50:59Quinine in tonic water absorbs and releases energy,
00:51:02making your drink look like it's from a fairy tale.
00:51:08There's an interesting connection between what we hear and what we taste.
00:51:13Scientists investigated and found that people worldwide link certain sounds with specific flavors,
00:51:19and they call it cross-modal correspondence.
00:51:22High-pitched sounds match up with sweet and sour tastes,
00:51:26while the lower, jarring sounds go hand-in-hand with bitterness.
00:51:30If it's staccato, think crunchy, and if it's smooth and flowing, think creamy.
00:51:36Some even found music that can enhance the taste of chocolate.
00:51:40In this study, when people listened to a high-pitched, sweet soundtrack while eating chocolate,
00:51:46they thought it was sweeter than when they'd heard a lower, more dissonant soundtrack.
00:51:56So consider this.
00:51:58People started making ridge patterns on coins in past centuries to fight counterfeiters.
00:52:03In the old days, cheaters cut off the smooth edges of coins and used that metal to mint new money.
00:52:09But with ridges, it became impossible to hide the cutting.
00:52:13These small cylinders on the charging cables are called chokes or ferrite cores.
00:52:19They're magnetic iron oxide that helps to prevent electromagnetic interference.
00:52:24In simple words, they protect your device from faults.
00:52:27We all know about these little pockets on jeans where people used to keep their pocket watches.
00:52:33But what about these small metal buttons?
00:52:35They help hold the fabric together.
00:52:37Weavers put the buttons where the jeans can tear during moving and straining.
00:52:41These small holes on some backpacks were designed to tie extra gear to them.
00:52:46So you can pass ropes through them and tie sneakers if you don't want to keep them inside your backpack
00:52:52or in your hands.
00:52:54This tiny dot next to the camera on your iPhone is a microphone.
00:52:58It helps to get good quality of sound while taking a video.
00:53:02The Spotlight feature on your Mac can be used not only for a quick search of files and apps.
00:53:08It also works as a calculator.
00:53:10Just type in a mathematical problem you need to solve.
00:53:14Spotlight also uses internal dictionary data.
00:53:17Enter any word in the search bar and you can get information about it.
00:53:21You've just bought a new bottle of oil.
00:53:24You're taking off the lid and looking at this little cork that you can tear off by pulling the loop.
00:53:29Take this thing out, but don't throw it in the trash.
00:53:32Put it back in an upside-down position to control the pour's flow by pressing your finger against it.
00:53:39Tiny ridges on the F and J keys on the keyboard help your fingers navigate during touch typing.
00:53:46When your index fingers are on these ridges, you know exactly where other letters are.
00:53:51The brushes on the sides of the escalators are not for polishing your shoes, but for your safety.
00:53:57These nylon bristles prevent your laces and clothes from getting inside the escalator's gears.
00:54:04No, that wouldn't be good.
00:54:06Most door handles are made of brass.
00:54:08This type of metal is good for fighting microbes.
00:54:11Bacteria can't multiply that much on such surfaces.
00:54:15These public toilet's cubicles don't look private for a reason.
00:54:20Huge gaps at the bottom were created to make you want to get out of there as soon as possible.
00:54:25Thanks to this design, there are almost no cubes.
00:54:28You can use a plastic lid from soda cups as a coaster.
00:54:32It has the perfect shape to hold your drink and keep a table surface from getting wet.
00:54:37Don't turn the lid upside down.
00:54:39Just put it on the table the same way it was on the cup.
00:54:42If you're stuck in a car during an accident and can't open the doors,
00:54:47you can use bars from the detachable headrest to break the window and get out.
00:54:52Remember those small plastic discs under the bottle lids?
00:54:56This little thing helps preserve vacuum inside bottles, keeping soda in a fizzy state.
00:55:02You've probably watched food heating in a microwave at least once in your life.
00:55:07Exciting, I know!
00:55:08But why do the developers make the door so dark?
00:55:12This black film is necessary to block electromagnetic fields.
00:55:16Tiny dots on padlocks next to the keyhole are designed to dry out the moisture if water gets inside the
00:55:23lock.
00:55:23Also, if the lock gets jammed or starts to rust, you can pour oil into it through this hole to
00:55:29fix the problem.
00:55:30A golf ball is covered with tiny craters for good aerodynamics.
00:55:36They're called dimples, and this design helps the ball fly further and more evenly.
00:55:42Some mugs have a little groove at the outside of the bottom.
00:55:45It helps water flow out and prevents it from accumulating when the cup is in the dishwasher.
00:55:51Sunglasses were first used not to protect your eyes from the sun.
00:55:55They used such glasses during Arctic expeditions.
00:55:58A huge amount of snow can blind you just like a bright flash.
00:56:02To save their eyes, they came up with these unique glasses.
00:56:07You can use any t-shirt not only for dressing, but also as a protective layer for your luggage.
00:56:12Just put your clothes on your suitcase as a cover and don't waste time plastic wrapping it.
00:56:18A button on the back of the shirt collar is there to keep your tie under the collar.
00:56:22Yes, people don't use it as intended because all ties are thinner now.
00:56:28But this button is still there as a decorative function.
00:56:31And here's the initial purpose of a tie.
00:56:34They created it in the 17th century Europe to tighten the collar.
00:56:38This way, people protected their necks from a strong wind.
00:56:42Then, they got used to this part of the outfit and made it a must-have accessory for royal gatherings.
00:56:48Soft pom-poms on hats were first invented several centuries ago.
00:56:53Sailors use them to avoid hitting their heads against low ship ceilings and ledges.
00:56:58They make most clothes hangers from cedar wood,
00:57:01since it contains many natural oils repelling moths that love to eat your clothes.
00:57:07A light bulb is spherical because such a shape allows the light to distribute evenly.
00:57:13Also, such light bulbs are cheaper and easier to produce.
00:57:16Ever found these pieces of fabric and new clothes?
00:57:20They're not just patches, but also testing subjects to use before washing.
00:57:25You can put this piece in the washing machine and see what happens to it.
00:57:29If everything is fine, then you can safely put your clothes in.
00:57:33Your ceiling fan has two modes of work, winter and summer.
00:57:37You need to find the switch on it.
00:57:39Push it up to activate the winter mode and down for the summer one.
00:57:43In summer mode, the fan pushes the air down.
00:57:47It pulls the air up in winter.
00:57:50Most people have this ground plunger in the bathroom.
00:57:53In movies, they use those to eliminate a blockage in the toilet.
00:57:57In fact, the plunger is to get rid of a blockage in the sink.
00:58:00For the toilet, you need another special device.
00:58:04The extra space under your oven is not for keeping pans and pots.
00:58:09You can put some dishes there.
00:58:11The heat of the stove will keep your meals warm.
00:58:14It's useful if you're waiting for friends late for dinner.
00:58:19You're taking a pack of popcorn out of a microwave after heating.
00:58:23See the little hole at the top of the popcorn bag?
00:58:26You can use it to get rid of small, unpopped grains.
00:58:29Shake the pack over the plate, and all the grains will fall out through the hole.
00:58:34Almost all people use a travel pillow incorrectly.
00:58:38Usually, they put two ends forward and lay their heads back.
00:58:41Try to turn the pillow on the other side.
00:58:44The arc should be under your chin, and the two ends should be directed back.
00:58:49Lay your head forward, and your neck will feel way more comfortable in this position.
00:58:53And you'll get a good nap.
00:58:56They create magnets in a horseshoe shape to increase their magnetic power.
00:59:01The blue part indicates the south pole, the red part, the north one.
00:59:05The two poles work simultaneously and increase the attraction.
00:59:10Thanks to the perfect aviation design, most planes can fly a long distance even without an engine.
00:59:17In 1268, Roger Bacon made the first written mention on using telescope lenses for optical purposes.
00:59:25Magnifying lenses inserted in frames were popular for reading, both in Europe and China at this time.
00:59:31So it's still a question if the West took it from the East or vice versa.
00:59:36If you find yourself in the middle of the sea without food, sorry, you can try fishing.
00:59:42You can use anything for bait.
00:59:44Your phone, watch, keys, and you can use laces as a fishing line.
00:59:48Tie the bait and throw it into the water.
00:59:51And good luck catching the fish that swallowed your phone.
00:59:54It's going to be a whopper.
00:59:56You can turn over the tab on a lid of soda cans and use it to hold a cocktail straw
01:00:02in place.
01:00:03The blue half of the eraser wasn't originally created to delete the ink.
01:00:07Initially, the blue part erased inscriptions and drawings on thick paper.
01:00:12The red part couldn't do it without leaving streets.
01:00:14But the blue one handled this task perfectly.
01:00:18Most of us tear sticking notes off incorrectly.
01:00:22Try not to do it from below, but from the side along the licking log.
01:00:26The paper will stick to the wall for longer this way.
01:00:30Ever wondered what these two holes in the lollipop stick are for?
01:00:34All the time, you say?
01:00:36Well, when they put the bar in hot syrup, the liquid flows inside.
01:00:41It creates a solid attachment for the plastic.
01:00:44And so it goes.
01:00:48If you ever find yourself stuck in the trunk of your car, stay calm.
01:00:53All cars are supposed to be equipped with an emergency latch
01:00:56to help open the trunk from the inside in the unlikely case it happens.
01:01:01These latches are so well thought out that they can be opened by people of all ages.
01:01:06More so, handles are designed to glow in the dark, too.
01:01:09You can even pull them with a mouth if there's not enough wiggle room to use your hands.
01:01:14Never mind how you ended up in the trunk in the first place.
01:01:16Moving on.
01:01:18If you're ever working with needle and thread, remember, you don't need to stick the needle
01:01:23directly into the spool.
01:01:24You may end up losing the needle altogether.
01:01:27Not to mention you can easily hurt your fingers.
01:01:30A lot of modern sewing kits these days come with a designated place for safeguarding the needles.
01:01:36It's located at the bottom part of the thread spool.
01:01:38You'll just need to pull it out.
01:01:40It's even made to hold multiple sewing needles at a time.
01:01:44Disposable ballpoint pens come with a little secret of their own.
01:01:48Did you ever notice that in some of them, there's a small hole in the plastic part?
01:01:53It's actually a rudimentary ventilation system.
01:01:56It's supposed to let the ink easily make it to the tip of the pen.
01:02:01Okay, I know it's in the name, but you really don't need to shake the seasoning shaker to get
01:02:06any product out.
01:02:07Don't believe me?
01:02:08Hey, you're not the only one.
01:02:10Go grab your favorite seasoning bottle out of your pantry.
01:02:13If it has one of those removable plastic caps, it's perfect for the experiment.
01:02:18Instead of shaking the bottle, try holding it from the plastic cap while it's upside down.
01:02:24Now, gently twist the bottle from side to side and, before you know it, you get some gorgeously
01:02:30flowing seasoning without having to wiggle the shaker and make a mess all over the stove.
01:02:36On the same note, most salt and pepper shakers should have ridges on the bottom of the glass
01:02:41portion.
01:02:42In case you get any seasoning stuck in there, place the bottom of the salt shaker against
01:02:47the bottom of the pepper shaker and wiggle it around so the ridges click with each other.
01:02:52The seasoning should easily pour out now without you having to open the bottle.
01:02:57In colder weather, you often have so many clothing layers on you that you can hardly feel the
01:03:02purse or back straps on your shoulder anymore, not to mention how fast they can slide off.
01:03:08Some jackets come with a built-in solution for that in the form of a small tab on the shoulder
01:03:13with either a hook or a button.
01:03:15It's meant to be opened and closed comfortably, so you can keep your purse in place at any time.
01:03:22You're most likely using it merely to peel the skin of potatoes, carrots, or cucumbers.
01:03:27But you can use your vegetable peeler for chopping fine strips of onion as well.
01:03:33Just cut the onion into quarters vertically and then start slicing.
01:03:37This might also help out with those embarrassing onion tears.
01:03:42Most people miss this one, but should you ever have a closer look at your toothpaste tube, you
01:03:47will surely see some sort of coloring there, either a dot or a block.
01:03:52Colors can vary.
01:03:53They can be black, green, red, or even blue.
01:03:57These color spots are actually meant to help the assembly machines back at the toothpaste factory.
01:04:01They recognize when and where these machines need to cut the toothpaste tubes and proceed
01:04:06to fold them for packaging.
01:04:08For most types of footwear, if there's anything that seems a bit out of place, always know
01:04:14that it's there for a reason.
01:04:15Most manufacturers don't put extra items on shoes just for fun.
01:04:19It would definitely be a waste of time and resources.
01:04:23For footwear, like boots, for example, there's often a small loop at the top back of the shoe.
01:04:28It's there to help you when you need to put the shoe on, since you can quickly pull on it.
01:04:33Plus, you can also hang the shoes somewhere, most likely to dry, since most boots are meant
01:04:39to be worn in the colder weather.
01:04:41Now, I've been guilty at least once of overdressing with a bunch of layers, just so I won't need
01:04:46to jam everything in my check-in bag.
01:04:49But does it become a problem when you actually have to get seated?
01:04:53What do you do with your coat or your jacket?
01:04:55Well, have a closer look next time you board a plane on the seat in front of you.
01:05:00The hook that keeps the tray table upright can double as a jacket hook.
01:05:05As long as you don't need to have any meals while in the air, you're good to go.
01:05:10Now, most mascaras expire within 3-6 months, I'm told, depending on the manufacturer.
01:05:16But you can help speed up that process if you're not careful enough.
01:05:20Continuously pumping the mascara wand, trying to mix in the product, actually pushes more
01:05:25air into the tube.
01:05:26This can make it dry much faster, and you evidently won't get the desired results with it anymore.
01:05:33There's an easy way to check if your mascara is still good enough to use.
01:05:37If you don't hear a popping noise when you take the brush out, you may very well need to
01:05:42go get yourself a new mascara tube.
01:05:45Now, I know we're living in the era of Bluetooth-connected devices, but for better quality sound, they still
01:05:52recommend using headphones that connect via audio jacks.
01:05:56Remember seeing black ridges on those jacks?
01:05:58They aren't there just to make them fit when you plug them into your phone or laptop.
01:06:03Made out of a special insulating material, these bands are meant to guard the wires when
01:06:08sound is being transmitted.
01:06:10Based on the number of bands, you can figure out which end goes where.
01:06:14Some empty space under noodles in the cup doesn't mean the company producing them wants
01:06:19to cheat you out of a full portion.
01:06:21No, no.
01:06:22It's a manner of keeping the noodles intact during their transportation.
01:06:26It also helps with the circulation of hot water that is poured over the products before
01:06:31you can enjoy them.
01:06:32The V-shaped neckline was initially designed to serve a bunch of objectives.
01:06:37First, as a way of prolonging the life of the garment that would maintain its shape over
01:06:41the years.
01:06:42It's also there to fit your head through the shirt in case it needs some stretching.
01:06:46This way, it ensures a snugger grip around the neck.
01:06:50Lastly, it helps absorb sweat in case you're wearing the shirt while exercising.
01:06:55Now, it's not necessarily a custom anymore, but you may have stumbled upon a dinner jacket
01:07:01with an additional mysterious pocket on the right side.
01:07:04Turns out, this pocket was used by men to easily reach their train tickets, since most
01:07:10of them had to travel to work every day.
01:07:12It helped them keep their jacket buttoned up, but also benefited from the use of a pocket.
01:07:17Now, it's only added as a decoration, and it doesn't serve an actual purpose anymore.
01:07:22Speaking of things we don't use these days, or at least for their initial purpose, did you
01:07:28know Play-Doh was originally a cleaning product?
01:07:31In the 1920s, the market was in need of a product that could help them wipe the wallpapered
01:07:37areas around coal-burning furnaces.
01:07:39The recipe for what we now know as Play-Doh was thus invented.
01:07:44It was manufactured in white only, and was supposed to clean wallpaper by being rolled
01:07:49back and forth over the dirt.
01:07:51It was only later, in the 1940s, that new products for cleaning wallpaper were brought
01:07:56up, and Play-Doh was redirected toward another area of the market.
01:08:01Now, while I enjoy a nice piece of toast for breakfast, isn't it pesky to have to clean
01:08:07out the toaster?
01:08:07Well, not anymore, since I recently found out that toasters have a slide or a panel at
01:08:14the bottom that helps get rid of all those annoying breadcrumbs easily.
01:08:20Now, there used to be a time when you could only have access to video games by inserting
01:08:25cartridges in your console of choice.
01:08:28These tiny objects gave many doctors a lot of headaches.
01:08:32People soon started popping up in hospitals after swallowing small game cartridges.
01:08:37Especially the younger generation.
01:08:40Nintendo, the company that manufactures the majority of these devices, had to come up with
01:08:45a creative solution to prevent these accidents.
01:08:47So, these days, Nintendo Switch cartridges are purposely coated with specific chemicals that
01:08:53can leave a really bad, bitter taste in the mouth.
01:08:56Not that I'd, you know, recommend you ever try and taste for yourself.
01:09:00Hmm.
