00:00:01So get this, an extra hole at the upper part of the sink has multiple hidden functions.
00:00:06First, in case someone forgets to close the tap, the water won't overflow and the bathroom won't get flooded.
00:00:12Second, thanks to that hole, the water drains faster and it gives an escape for the air, helping the water
00:00:17flow down.
00:00:20Those two holes on a side of any Converse shoe are not only to let the stinky air out.
00:00:25Sure, breathability is important for any athlete.
00:00:27The second reason is that athletes lace through those holes to get a better grip.
00:00:34Donuts have a hole in the middle and it doesn't stand for O in donut.
00:00:38It's not designed for an easier grip either, though it can be quite convenient.
00:00:42It's actually made this way for mass baking so that they can cook all the way through evenly.
00:00:49Baby carrots are tiny and, unlike regular carrots, wet.
00:00:53Baby carrots aren't some special sort of carrots.
00:00:56They're actually made of regular carrots by cutting off the skin and outer layers and then polishing them to look
00:01:02that pretty.
00:01:02The problem is that they can't retain moisture.
00:01:05A regular carrot retains some water inside because of the layers that locks it in.
00:01:09Once they're chopped out, baby carrots can dry out easily.
00:01:12So, they usually sell them in bags with some water inside.
00:01:17Toy stores are filled with Beanie Baby plush toys.
00:01:20And a detail that is even more iconic than their huge eyes is their tags saying TY.
00:01:26That's a small manufacturing company not so many people have heard of.
00:01:29Beanie Babies appeared in 1993 and they went insanely popular.
00:01:34TY is the name of the company, but it's not an abbreviation.
00:01:37It's the actual name of the company's founder, H. Ty Warner.
00:01:43Most metallic zippers have a hidden lock inside them to save you from awkward situations, such as an undone fly.
00:01:50Oh boy.
00:01:51Don't leave the zipper handle in an upward position.
00:01:54When you pull it downwards, it automatically locks.
00:01:56It's all thanks to those tiny grooves hidden underneath the handle.
00:02:02Almost any public toilet has a large gap between the floor and the door.
00:02:07The reason for such a zero privacy thing is to actually minimize the level of privacy and comfort,
00:02:12so that people wouldn't stay there long and there'd be no lines.
00:02:15It's also easier to clean and safer if some emergency occurs.
00:02:22Headrests in a car are about comfort and detachable headrests are about safety.
00:02:27If you pull the headrest out of a seat, you'll see two bars, which are quite sturdy.
00:02:32If you ever get locked or trapped in a car, you can get out of there smashing the window with
00:02:37these bars.
00:02:41Many cups and mugs have little grooves on the bottom on purpose.
00:02:45They're designed for dishwashing machines.
00:02:47The grooves let the water flow and not spill over your feet when you take the cup out.
00:02:51Also, those grooves let the air flow so the cup doesn't crack even if the tea is scalding.
00:02:59Almost all measuring tapes have a metal tip with a small slot on the end.
00:03:03You can use this slot to hang the tape on a nail or a screw to make measurements without anyone's
00:03:09help.
00:03:10Sometimes this tip has a row of sharp points along the edge on one side.
00:03:14That comes in handy when you want to leave a mark without using a pencil.
00:03:20Doorknobs are usually made of brass, bronze, and some other copper alloys for a reason.
00:03:24They have an antibacterial effect, so they stop microbes from spreading.
00:03:29They get rid of a range of harmful germs pretty fast within a couple of hours.
00:03:34But don't forget to wash your hands anyway.
00:03:38Grocery carts have loops for a reason.
00:03:41You don't want to put your jacket in a cart next to potatoes and onions.
00:03:44Hang it on a loop.
00:03:46This little hook-like thing is there to help you better organize the space in your cart.
00:03:50The carts also have a super handy grid.
00:03:54Whenever the cart's full, you just need to lift the grid and attach the shopping basket for extra purchases.
00:03:59Placing it in between the horizontal bar above the wheels and the hooks the grid has.
00:04:06A point in an ointment cap is there for a reason too.
00:04:09Most tubes are usually sealed with foil, and it's better to avoid opening it with fingers
00:04:14unless you're ready to say goodbye to your nails.
00:04:16A point easily opens even the most safely sealed tube.
00:04:22Silica gel can often be found in different things you buy like bags, shoes, and many others.
00:04:27Don't throw it away.
00:04:29It's meant to absorb excess moisture.
00:04:31So anytime your shoes are a bit wet, just throw in a packet with silica gel.
00:04:37People used to co-live with rats, and these guys like gnawing on everything they see in their way, including
00:04:43paper.
00:04:45Still, rats weren't able to chew more than the space left on the margins.
00:04:51That black grate on a microwave isn't just some fancy decoration.
00:04:54It's called a Faraday shield, and it prevents the rays from escaping the microwave.
00:04:59It also speeds up the heating, so you can enjoy yesterday's leftovers faster.
00:05:04It may also block phone signals, so if you're tired of numerous calls, just put the phone into a microwave.
00:05:10But don't turn it on.
00:05:14All Tic Tac containers are designed to dispense one Tic Tac every time you open it.
00:05:20The lid has the same shape as the candy.
00:05:22Turn the container upside down, gently shake it, and open it slowly.
00:05:26You'll notice only one candy stuck between those lid grooves.
00:05:29So if you just open the container and shake it until five or even more candies fall into your mouth,
00:05:34it means you've been eating Tic Tacs wrong all this time.
00:05:41Those little holes in the airplane windows are designed to control the cabin pressure.
00:05:45They also protect the windows from fogging up as the temperatures drop and rise.
00:05:49By the way, the airplane window is round for a reason.
00:05:52This way, pressure is evenly distributed so it doesn't get deformed.
00:05:59Blue bristles on a toothbrush are actually an indicator that it's just about time to change the brush.
00:06:04As the bristles get in contact with water, the blue, or whatever other, pigment fades away.
00:06:09So the more you use it, the duller the color becomes.
00:06:14A triple handle on a jerry can is there to make it easier for two people to carry it and
00:06:18distribute the fuel evenly.
00:06:20Gas cans often have a second hole that actually needs to be unkept too, before you pour the gas.
00:06:25The air passage will prevent it from pouring out, so no more fuel waste.
00:06:31Jeans first appeared in 1873.
00:06:34They were invented by Jacob Davis and Levi Strauss.
00:06:38Davis was a tailor who was producing covers and tents,
00:06:41and Strauss was a businessman who, among other things, was selling cloth.
00:06:46The first jeans were made by Davis from denim, the fabric he bought from Levi Strauss & Co.
00:06:53Together, they patented the design.
00:06:55Blue was a standard color for denim that was dyed using an indigo dye.
00:07:00The blue color is a tradition that is still often followed today to replicate the original look of a pair
00:07:05of jeans.
00:07:06Jeans also have metal rivets, and they've been there from the very beginning.
00:07:10Jacob Davis, the man who made the first pair of jeans, added copper rivets to spots where pants were more
00:07:16likely to rip, flies and pockets to make them stronger.
00:07:20Today, they have more of a decorative purpose since they're distinctive and traditional for jeans.
00:07:27Another special thing about jeans is those tiny pockets they have that seemingly serve no purpose.
00:07:32Well, maybe it's true now, but years ago, when many cowboys were wearing jeans, the pocket was made specifically to
00:07:38keep a pocket watch there.
00:07:40Also, back then, a pair of jeans had just four pockets, that tiny pocket, the watch pocket, two big pockets
00:07:46in front, and just one pocket on the back.
00:07:51Many zippers have the letters YKK engraved on them.
00:07:55It's an abbreviation that stands for the name of the company that can be translated as Yoshida Manufacturing Shareholding Company.
00:08:02This Japanese company is the largest zipper manufacturer in the world, so they put their initials on all the zippers
00:08:09they produce.
00:08:10That's around half of the zippers in the world.
00:08:13And that's why you see their zippers more often than any other zippers.
00:08:18Those little white golf balls have dimples all over them.
00:08:21It turns out they aren't there just randomly.
00:08:23At first, golfers were playing with a smooth ball.
00:08:26With time, the ball would get all punched and damaged, but also, it would start to travel way further.
00:08:31The reason here is aerodynamics.
00:08:34Dimples allow the air to flow more smoothly around the ball, taking it further.
00:08:39So the idea was adopted, and the balls got their dimples all around, allowing them to travel longer distances.
00:08:47Now, if you're as watchful as I am, you've probably noticed those zigzag patterns on the edges of some packages,
00:08:53like bags of chips or chocolate bars.
00:08:55It's clear that they're there to make it easier for you to tear the plastic.
00:09:00But why does it tear so easily?
00:09:02Now, plastic is made of long molecules called polymers.
00:09:06You can compare it with a fabric made of long threads.
00:09:09But the scale is much smaller, and these strands aren't actually woven together.
00:09:14What ridges do is remove the support of the surrounding polymer fibers.
00:09:19When the edge is flat, the molecules are surrounded and kind of protected by their mates.
00:09:24But if the edge is uneven, molecules on the peaks of the ridges are much more exposed to mechanical damage.
00:09:31Plus, such an uneven edge allows you to apply more force to a specific point, the groove.
00:09:37And once that point fails, the groove moves to the next point, causing more tearing.
00:09:42And this process continues until you stop applying the force or until you're done tearing the packaging apart.
00:09:49But this isn't the only packaging secret.
00:09:52I'm about to reveal the most unexpected packaging facts.
00:09:56Now, is this what the future of packaging looks like?
00:09:59A Swiss company has invented a magic juice box.
00:10:03It's made of agar-agar seaweed gel and water.
00:10:06It can only contain short-term smoothies and juices.
00:10:09The box also withers at the same rate you consume the product inside.
00:10:14Wow! Doesn't it sound like the future is here?
00:10:17That overwhelming smell of coffee that literally hits you once you open a jar with instant coffee?
00:10:23This scent is actually just a coffee aroma sprayed onto the lid.
00:10:27It's done to provide you with the enticing smell of freshly ground coffee.
00:10:32One of Korea's leading manufacturers of instant noodles has come up with innovative packaging for their production.
00:10:39It can be safely used in microwaves.
00:10:42The company claims that some additional material used in this packaging can remain intact without melting, even at high temperatures.
00:10:49Well, it'll definitely make the process of heating up your lunch much faster.
00:10:54Now, almost all food we consume has an expiration date.
00:10:59But this rule doesn't apply to water.
00:11:01Mmm.
00:11:02But how come there's an expiration date on every water bottle?
00:11:06There's no paradox here.
00:11:07This expiration date refers to the bottle, not the water inside.
00:11:12They say that regardless of the brand, all chips have a best before date that ends on a Saturday.
00:11:19It's because a production week starts on a Sunday and correspondingly ends on a Saturday.
00:11:25Well, I've checked my stash and it seems to be true.
00:11:29Go look at yours and write in the comments what you found out.
00:11:33Bubble wrap was originally designed to serve as textured wallpaper.
00:11:36It was invented in 1957 by engineers Mark Chavons and Alfred Fielding in New Jersey.
00:11:44They sealed together two shower curtains trapping inside a smattering of air bubbles
00:11:48and wanted to sell the resulting product as an innovative kind of wallpaper.
00:11:53Unfortunately, the product turned out to be a failure as wallpaper.
00:11:57Then the inventor started selling it as greenhouse insulation.
00:12:01But it wasn't until 1961 that the material's protective qualities were discovered.
00:12:07And the first client that used bubble wrap as a packaging material was IBM.
00:12:12This company used it to protect its big IBM 1401 mainframe computer during shipping.
00:12:19Now, people love personalized products.
00:12:22According to researchers, a whopping 52% of online customers are more willing to repeat their purchases from a company
00:12:29when they get personalized shipping boxes.
00:12:32If you've ever seen someone unboxing Apple products, you probably noticed that the company used very laconic packaging.
00:12:40This probably made you think that they put no effort into it.
00:12:43But that's not true.
00:12:44To achieve such a level of perfect simplicity, Apple has created a real culture around its packaging.
00:12:51The company's headquarters even have a special place where they come up with packaging designs for new products.
00:12:57The egg carton was designed in 1911 by newspaper editor Joseph Coyle from British Columbia.
00:13:05The main goal of this invention was to resolve a dispute between a local farmer and a hotel owner who
00:13:11kept complaining that the farmer's eggs were delivered broken.
00:13:14So, necessity is the mother of invention.
00:13:18Nike has created a shoe box made completely out of recycled trash materials, mainly drink containers.
00:13:26This box also allows its owner to wear it as a backpack.
00:13:30Now, paper packaging for food goes all the way back to China to the 2nd century BCE.
00:13:36At that time, food was often wrapped in thin sheets of mulberry bark.
00:13:41And later, the idea spread all over the world.
00:13:44And in 1879, one accident literally changed history.
00:13:49A worker from a paper bag factory in Brooklyn set the machine he used to the wrong settings.
00:13:55And instead of creasing small bags, it cut through them.
00:13:59When the owner of the factory readjusted the settings on the machine, he realized that it could cut and crease
00:14:05at the same time.
00:14:06This led to the appearance of mass-produced paper board boxes.
00:14:10Now, researchers have found out that the process used during the manufacturing of cardboard boxes can ward off germs.
00:14:18Hear me out!
00:14:19To make cardboard, they shape layers of paper and bond them at a temperature of up to 200 degrees Fahrenheit.
00:14:25That's hotter than most harmful bacteria can withstand.
00:14:29That's why cardboard boxes are a rather safe way to package foods.
00:14:33After all, they come out of the manufacturing process sanitized, even when they're made of recycled materials.
00:14:40That little open jar icon on cosmetic packaging is the PAO, period after opening symbol.
00:14:48It informs consumers about the period of time a product may be used after the package is unsealed.
00:14:53The symbol, featuring a number followed by the letter M for months, can be seen on almost all cosmetic products.
00:15:02Some plastic milk containers have dents on their sides.
00:15:05These dents serve several purposes.
00:15:07For one thing, when the milk spoils, this process usually causes swelling and high-pressure buildup inside the container.
00:15:15That's when the dent comes in handy.
00:15:17It pops out and doesn't let the jug blow up.
00:15:20Plus, if you decide to freeze the milk, it will expand like any other liquid.
00:15:25And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
00:15:32Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
00:15:38That's because soda contains carbon dioxide.
00:15:41It's a gas that can expand once the bottle is heated.
00:15:44If there's no gap in the bottle, it can break because of the pressure building inside.
00:15:50Also, when you open your drink, the gases go out in the form of bubbles.
00:15:54And the drink is likely to overflow.
00:15:57The gap helps with this problem, too.
00:15:59Now, about those horizontal lines on plastic bottles.
00:16:03They help hold bottles up.
00:16:05Some bottles are produced from soft plastic.
00:16:08Without the lines, they wouldn't keep their shape.
00:16:11Instead, they would twist easily or even break.
00:16:14Number 57 on a Heinz ketchup bottle has nothing to do with the product label.
00:16:19The truth is that the place with the numbers is the very sweet spot you should tap to get the
00:16:25ketchup flowing.
00:16:25So, stop smacking the bottom of your sauce bottle and tap the 57.
00:16:31By the way, if you've been wondering why the number is exactly 57, not 34 or 89,
00:16:38this comes from the historical advertising slogan, 57 Variety, created by the Heinz Company located in Pittsburgh, USA.
00:16:46This advertising campaign told customers about the numerous products manufactured by the company.
00:16:53Now, at first sight, everything is obvious about plastic lids on disposable cups.
00:16:58To keep your beverage inside, right?
00:17:00But that's not all they're capable of.
00:17:02As soon as you find a cozy spot and get ready to sip on your drink, you can use the
00:17:08lid as a coaster.
00:17:09If you look carefully, you'll notice special ridges that hug the bottom of your cup snugly.
00:17:14It's a snuggly hug.
00:17:16The size of each lid fits the bottom of the corresponding cup.
00:17:23And the soft round part under a soda bottle cap keeps the carbonation from escaping.
00:17:29Without it, your pop would go flat in no time, probably even before you buy it.
00:17:38New iPhone models with large screens have a convenient option called reachability.
00:17:43Thanks to this function, you don't have to struggle to reach the top of the screen.
00:17:47This feature can be found in the phone's accessibility settings.
00:17:51It allows you to lower your screen down.
00:17:53The rumble strips on the side of the road are there to wake up sleepy drivers who doze off behind
00:17:58the wheel.
00:17:59When your tires drift off onto these strips, the noise and vibration work like an alarm clock.
00:18:05Most kitchen shears have metal, plier-like teeth in the middle.
00:18:08They allow you to use the device for multiple purposes.
00:18:11They're placed between the handle grips for you to crack nuts, crab shells, and whatnot.
00:18:16You can also open jars and bottles with their help.
00:18:19Some people even use these teeth to remove stems from herbs.
00:18:22If your audio jack has three rings, it means your device can produce stereo sound,
00:18:28and your earphones have the microphone function.
00:18:30The black grating on a microwave oven door is called a Faraday shield.
00:18:35It stops microwaves from getting away.
00:18:37If they do, your food won't cook properly.
00:18:40The digits on an egg can tell you a lot about the product.
00:18:44In many countries, there's a special labeling system.
00:18:47The first number indicates the method of production.
00:18:49The following two-letter code stands for the country where the egg was produced.
00:18:53And then you can find a registration number.
00:18:56It indicates the laying hen establishment.
00:18:58The first number in this code can vary from zero to three.
00:19:02Zero means it's an organic egg.
00:19:04One, it's a free-range egg, which means it was produced by a hen that was allowed to wander around
00:19:09outdoors.
00:19:10Two stands for an egg produced in a deep-litter indoor housing.
00:19:13Three, you're about to buy a cage farming egg.
00:19:17A black band that runs along the edges of your windshield is called the Frit.
00:19:22It's a baked-in ceramic paint that starts as solid black bands near the edge of the windshield.
00:19:27Then it dissolves into smaller dots.
00:19:30The Frit makes the glass rougher, and the adhesive sticks to it better.
00:19:34The Frit protects the urethane sealant.
00:19:36It's the substance that fixes the glass to the frame.
00:19:39It also prevents the sun's ultraviolet rays from melting the adhesive.
00:19:43As for the black dots, they help distribute the temperature in the car more evenly.
00:19:47They're aesthetically pleasing, too.
00:19:50Without them, the contrast between the glass and the dark band would be too obvious.
00:19:55If you see a pair of jeans with an extra loop, those are special jeans for cyclists.
00:20:00They're likely to belong to the commuter clothing line.
00:20:03And the loop's main purpose is to hold your bike lock.
00:20:07Many zipper sliders have outer rings, especially if such sliders are supposed to be used together.
00:20:13These rings are added so that you can connect the sliders with a lock and keep pickpockets away.
00:20:19Keyboards come with little legs.
00:20:21They were designed for you to be able to tilt your keyboard.
00:20:24This way, you can actually see which keys you're hitting.
00:20:27At the same time, a flat keyboard doesn't make your wrists so tired.
00:20:31And people who can type without looking at the keyboard don't need those legs whatsoever.
00:20:35An olive spoon is usually made of stainless steel and has a small hole cut in its bowl-shaped head.
00:20:42The main purpose of this utensil is to lift olives, cherries, pickled garlic, and other products from liquid-filled jars,
00:20:49cans, or bowls.
00:20:49The hole in the middle allows you to drain the liquid gathering in the spoon fast and easily.
00:20:55What'll they think of next?
00:20:57Donuts are shaped like rings because, otherwise, they get overdone at the edges and remain uncooked and gooey inside.
00:21:04Make a hole in the center and both the outsides and the insides will be cooked at the same time.
00:21:09Round-shaped donuts with no holes are usually filled with custard, cream, or jelly.
00:21:14Mmm.
00:21:16Such donuts don't have any corners, which means there are fewer weak spots for the filling to spurt out from.
00:21:22If you grab a full juice box a bit too firmly, you can get sticky liquid all over the place.
00:21:27To avoid such situations, flip up the tabs on the sides of the juice box.
00:21:32You can use them to hold your drink.
00:21:34Some cars have a tiny coffee cup sign on the dashboard.
00:21:38It's the vehicle's anti-drowsiness mechanism.
00:21:41Some manufacturers equip their cars with a drowsiness detection system.
00:21:44It analyzes the speed, wheel angle, and lane deviations and figures out if it's time for the driver to take
00:21:51a break.
00:21:52If it is, the vehicle makes several audio signals and the coffee cup sign starts to flash.
00:21:58Produce stickers on fruit and veggies you get at the supermarket are full of information.
00:22:02If there's a four-digit code on the sticker, the product was grown conventionally.
00:22:07In most cases, it also means that pesticides were used in the process.
00:22:11If the product is organic, its sticker has five digits, and the first one is nine.
00:22:17Genetically modified products also have a five-digit code, but the first number is eight.
00:22:23Sugar used to be sold in sugar loaves.
00:22:25Those were tall, hard cones.
00:22:28At those times, to get sugar ready for tea, people had to use special hammers to break a loaf apart
00:22:34first.
00:22:35After that, they cut the sugar into smaller and more nicely shaped lumps.
00:22:39Only in the middle of the 19th century, people invented the first press that cut sugar into cubes.
00:22:45This way, the product was easier to store and transport.
00:22:47A little hole in the end of your wrench can provide your screwdriver with some extra torque.
00:22:53Just slide the end with the hole over the screwdriver.
00:22:56You can also use this method when the angle is awkward.
00:22:59While driving, when it's already dark, you might get blinded by the headlights of the car moving behind yours.
00:23:05If you have a manual rearview mirror, find a tab at the bottom and flip it.
00:23:10The mirror has a reflective material behind its glass.
00:23:13By flipping the tab, you change the angle of this material, dimming the lights in the mirror.
00:23:18Most ice cream scoopers come in different colors.
00:23:21It has nothing to do with aesthetics.
00:23:23The color indicates the size of the scoop.
00:23:26This way, you can easily figure out how many scoops you'll need to fill 32 ounces.
00:23:31Wow, a 32-ounce sundae! Sign me up!
00:23:34Some caps on small tubes are hollow on top and have a little spike inside.
00:23:39Its purpose is to break the foil sticker sealing the tube.
00:23:42The neck fits right in this hole, and the spike is designed to break the seal.
00:23:47This way, you don't need to tear the tiny foil seal off with your fingers.
00:23:51The letter R in a circle on the product's packaging means that the trademark is officially registered.
00:23:57Once it's done, the trademark's owner has the right to place this letter on all their products.
00:24:02They can also sue anyone who tries to use their trademark.
00:24:06A gas pump usually has a small metal latch or hook on its handle.
00:24:11That's a trigger lock.
00:24:12You can use it to lock the handle in the open position.
00:24:15Then the gas will keep pumping even if you walk away.
00:24:19Coins used to be shaped randomly or have no shape whatsoever in the past.
00:24:23Dishonest people used it to their advantage.
00:24:26They stole valuable metals the coins were made of by chipping their corners off.
00:24:30It was illegal, and to prevent this kind of fraud, round coins were invented.
00:24:35After that, it became easy to instantly notice when a coin had been fiddled with.
00:24:40Those two holes in a lollipop stick are there to hold the candy in place.
00:24:45When the stick is dipped in hot liquid syrup, it flows into the holes and solidifies.
00:24:49Now your suite is there to stay.
00:24:52Fabric squares that come with clothes are for you to try out your cleaning products on them first.
00:24:57This way, you won't ruin the entire item once you decide to wash it.
00:25:01The holes in the bottoms of earphones allow air to circulate up and through the speakers.
00:25:06It helps to increase low frequencies, making the bass sound deeper.
00:25:11The sound quality also becomes much better.
00:25:13Don't I sound better? Thank you.
00:25:15You can adjust your stapler so that it staples documents together only temporarily.
00:25:20It's done by rotating the crimp area.
00:25:23Most staplers have two options for stapling.
00:25:25One is standard, but the other side bends staples away from the center.
00:25:29Later, when you don't need them anymore, you can easily remove them by hand.
00:25:34If you store peanut butter jars upside down, the oil will move to the bottom and all the solids will
00:25:40be on top.
00:25:41Hey, don't laugh. That matters to some people.
00:25:44You don't want to get caught with your peanut butter down.
00:25:48Road and construction workers are usually dressed in orange
00:25:51because the bright orange hue is visible even in bad weather.
00:25:55It's the most effective color to attract attention and alert people.
00:25:59No wonder lots of safety jackets and traffic cones are orange as well.
00:26:03The stop sign has an eight-sided shape to help drivers recognize it easily, even if they see it from
00:26:08the back.
00:26:09And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing the stop sign with any other
00:26:16at night.
00:26:17The rumble strips on the side of the road are placed there to alert drivers who doze off behind the
00:26:22wheel.
00:26:23When their tires move over these strips, the noise and vibration work like an alarm clock.
00:26:27There are magnetic locks on fuel hoses at gas stations.
00:26:32They come in handy if someone drives away with the gas nozzle still attached to their car.
00:26:36In this case, the lock detaches the hose automatically.
00:26:40Oh, that's embarrassing.
00:26:42Gasoline looks like a rainbow in a puddle because it can't mix with water.
00:26:45It forms a thin membrane over it.
00:26:48When light reflects from it and the water at the same time, you've got a rainbow.
00:26:53A triple handle on a jerry can is there to make it easier for two people to carry it and
00:26:58distribute fuel evenly.
00:27:00Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.
00:27:06The air passage will prevent it from pouring out, so no more fuel waste.
00:27:11Most gas cans have two holes with caps, a bigger and a smaller one.
00:27:16You're supposed to uncap the smaller hole before pouring gas inside the bigger one.
00:27:20It'll prevent the liquid from glugging and spilling all over your clothes and the ground.
00:27:25Another little thingy we often neglect is a point on an ointment cap.
00:27:30Most tubes are usually sealed with a plastic film or a foil,
00:27:33and opening it with your fingernails isn't the best idea.
00:27:36A point easily opens even the most safely sealed tube.
00:27:41You can use most screwdrivers together with a wrench to create more torque.
00:27:46Just place the wrench over the handle of the screwdriver.
00:27:49This way, you'll need to apply a lot less force than before.
00:27:53You'll also be able to get to hard-to-reach areas more easily.
00:27:57They install cameras in shops, banks and hospitals to monitor everything.
00:28:01If something happens, you can call the police or rescuers.
00:28:06The camera really helps to solve a lot of problems.
00:28:08Why are there no cameras on planes?
00:28:11The crew keep order on the plane, but they won't be able to do anything if something serious happens.
00:28:17Besides, there's nowhere to run on the plane.
00:28:20During the flight, the cameras are useless.
00:28:22And after the flight, the words of the passengers work ideally instead of cameras.
00:28:27So, if cameras do no good, then why spend money on them?
00:28:32Water is great at cleaning stuff because it has triangular molecules.
00:28:35They're made of one oxygen and two hydrogen atoms .
00:28:40Such molecules have slightly different charges on their opposite sides, pretty much like magnets.
00:28:46That's why water easily sticks to other molecules, including those that make up dirt.
00:28:50Lots of private houses have triangular-shaped roofs because this allows rain, snow and fallen leaves to slide off the
00:28:57slope.
00:28:58If all this stuff piled up on top of your house, one day, your roof would collapse.
00:29:04When a storm is coming, clouds seem to turn dark, but it's just an illusion.
00:29:08Thin clouds on a sunny day let the light through easily.
00:29:11They also scatter all the colors of the light spectrum.
00:29:15This makes us perceive the clouds as white, but the thicker the clouds are and the more water droplets they
00:29:21contain,
00:29:21the less light they let through and the darker they look.
00:29:25A good doorknob is the one made of brass, bronze, or some copper alloys.
00:29:30These metals have an anti-germ effect.
00:29:33Bacteria spread way slower on them.
00:29:36They also get rid of germs pretty fast, within a couple of hours.
00:29:40Nope, it doesn't mean you don't have to wash your hands.
00:29:44Diamonds have such symmetrical shape to show you their brilliance.
00:29:47Initially, the gems aren't so beautiful.
00:29:50They go through several stages of cutting, and then become pieces of elegance.
00:29:55Most of these stones have a round shape with slightly pointed corners.
00:29:59Diamonds shine the brightest in this shape.
00:30:02Why are there two holes in the socket?
00:30:05The left hole is neutral, the right hole is not.
00:30:08And the gap underneath is ground.
00:30:11Electricity needs to flow through the chain.
00:30:13The current flows from the hot slot, passes through your phone charger, for example,
00:30:18and then goes through the neutral hole.
00:30:21Ever wondered what that small pocket on your jeans is for?
00:30:24People used to wear watches on chains.
00:30:26That small pocket was meant for it.
00:30:29Now, almost no one wears such a watch, but the pocket remains.
00:30:32You can still keep something small in there, like a ring.
00:30:36In London, there are some poles that look like street lamps, but there are no bulbs.
00:30:41Well, their official name is stink pipes, and they're a thing of the past now.
00:30:46But they used to come in handy back in the 19th century.
00:30:48These hollow poles would vent away the air and explosive gases with bad smells to prevent, shall we say, unwanted
00:30:56consequences.
00:30:58Most kitchen shears have metal, plier-like teeth in the middle.
00:31:01Between the handle grips, they can help you crack nuts, crab shells, and other tough products.
00:31:07You can also open jars and bottles or remove herb stems with their help.
00:31:12Leather often looks dull to the eye because it's covered with itsy-bitsy scratches and scrapes.
00:31:18They scatter the light that hits the material.
00:31:20When you coat your shoes in a layer of wax, you fill these tiny crevices.
00:31:25The surface becomes smoother, and the rays of light bounce off it more evenly.
00:31:29That's why the leather looks shiny.
00:31:32Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
00:31:38Yellow and light green hues are the most popular because they don't prevent you from seeing the text after black
00:31:44and white photocopying.
00:31:46Photocopiers perceive yellow and light green marks as very pale and don't print them.
00:31:51They make magnets shaped as a horseshoe because this increases the magnetic force.
00:31:57Colors matter, too.
00:31:58The blue part indicates the south pole.
00:32:00The red part, the north pole.
00:32:02The two poles work simultaneously and increase the attraction force.
00:32:07The dime-sized holes in elevator doors is actually a keyhole.
00:32:12If the doors get stuck, an operator can open them manually thanks to this hole.
00:32:16They'll just insert a special key.
00:32:19The tiny hole in the airplane window is there to balance air pressure.
00:32:23The window has three layers.
00:32:26The outer pane is extremely sturdy.
00:32:28It can withstand air pressure differences during takeoff and landing.
00:32:32The inner pane, which is the closest to you, is made of cheaper materials.
00:32:37It prevents potential damage to the window.
00:32:39The hole itself is in the middle pane.
00:32:42It not only balances the pressure but also prevents the window from fogging.
00:32:47The Persever brushes are there for your safety.
00:32:50They do not allow you to come too close to the edge of the escalator.
00:32:53This way, your clothes do not end up between the steps.
00:32:57You see the sun as yellow or orange.
00:33:00Because the atmosphere of our planet scatters such colors as blue, green and violet.
00:33:05This is also why the sun looks warmer at sunrise and sunset.
00:33:09Go shopping for some oranges and I'm sure you'll get them in a red mesh bag.
00:33:14You'll rarely see them lying around without one of those.
00:33:17It's pure marketing and that color isn't a random choice.
00:33:20When packed in a red mesh bag, oranges appear more orange, fresher and more appealing to you.
00:33:27So, you're more likely to buy them, right?
00:33:29Lemons are usually sold in green mesh bags for a similar reason.
00:33:33If you pack them in red, they'll appear more orange.
00:33:36Green goes better with yellow and makes those lemons stand out.
00:33:41Mattress manufacturers make a limited number of different mattresses
00:33:45and the only way to make them look different is to come up with a fancy stitching pattern.
00:33:49Two mattresses of two different companies might be the exact same quality but cost differently.
00:33:55Most people will never know it and will decide that different patterns mean something in terms of quality.
00:34:00So, when shopping, don't mind the pattern at all.
00:34:04Almost all hotels have white bedsheets.
00:34:07They choose this color specifically to show how high their standards of cleanliness are.
00:34:12The whiter and brighter the sheets are, the more luxurious the hotel seems.
00:34:16It's much easier to see dirt and stains on white linen.
00:34:19It's like proof that you've checked into a clean room.
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.
00:36:12Research 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.
00:36:24The results show that companies are misleading people by advertising these products by labeling them as healthy, natural, and 100
00:36:33% 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 it later without losing
00:36:45too much moisture.
00:36:47The drawback of all these additives is that they affect the nutritional value of the chicken breast.
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 menu item.
00:37:11Yet, some chicken sandwiches have the same amount or even more sodium than a cheeseburger with medium 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.
00:37:26This means the white meat in the sandwich will appear juicier to you.
00:37:30Any word you see in the ingredients section that contains phos is a phosphate additive, so it's best to avoid
00:37:37them.
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.
00:37:57You see, home-cooked chicken has 0 grams of carbs,
00:38:00but the study samples had added sugar and up to 10% of the calories in the chicken breast comes
00:38:06from 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 research, you can decipher
00:38:24many 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.
00:38:51Experts 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 962 milligrams of
00:39:12sodium.
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,
00:39:51look under the ice chute of the soda machine in places where you can get your own drink.
00:39:54There you go, inspector.
00:39:56You solved the case.
00:39:58Various studies say that if such machines aren't cleaned correctly,
00:40:02dirty, 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.
00:40:35Many 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.,
00:40:50or between 6 p.m. and 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.
00:41:00Fast 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, yet they want you to take advantage of the first 20
00:41:39minutes 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,
00:41:54but most of these companies are using cleaning products that have 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 showed up early the next day.
00:42:09You 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.
00:42:19I'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 bright siders 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.
00:43:07They'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?

00:43:50You 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.
00:44:06Inside, it keeps on growing and uses the stored glucose as fuel.
00:44:12Nothing out of the ordinary so far.
00:44:14But 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.
00:44:34To 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?
00:45:13They 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,
00:45:23stick to 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.
00:45:41So you can cook them forever.
00:45:43They 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,
00:45:57the outside 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.
00:46:24Then, 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,
00:46:33trapping the fortune inside like a tasty time capsule.
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.
00:46:53The moment you speak that term, you're tempting the employees to charge more.
00:46:59Instead, go for something like,
00:47:01a 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.
00:47:21Why?
00:47:22Because cheese is becoming more and more valuable.
00:47:26The 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, the 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.
00:47:56The 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, supply 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.
00:49:25These 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 the 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 3 to 5 cups, but when winter hits, they can reach 10 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.
00:50:32The secret behind this glow is pretty simple.
00:50:36Tonic 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, gets all excited, and then releases it as visible light.
00:50:59Quinine in tonic water absorbs and releases energy, making 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, and they call it cross-modal correspondence.
00:51:22High-pitched sounds match up with sweet and sour tastes, while the lower, jarring sounds go hand-in-hand with
00:51:29bitterness.
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 listen 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.
00:51:56If you ever find yourself stuck in the trunk of your car, stay calm.
00:52:00All cars are supposed to be equipped with an emergency latch to help open the trunk from the inside in
00:52:06the unlikely case it happens.
00:52:08These latches are so well thought out that they can be opened by people of all ages.
00:52:14More so, handles are designed to glow in the dark, too.
00:52:17You can even pull them with a mouth if there's not enough wiggle room to use your hands.
00:52:21Never mind how you ended up in the trunk in the first place.
00:52:24Moving on!
00:52:25If you're ever working with needle and thread, remember you don't need to stick the needle directly into the spool.
00:52:32You may end up losing the needle altogether.
00:52:34Not to mention you can easily hurt your fingers.
00:52:37A lot of modern sewing kits these days come with a designated place for safeguarding the needles.
00:52:43It's located at the bottom part of the thread spool.
00:52:46You'll just need to pull it out.
00:52:48It's even made to hold multiple sewing needles at a time.
00:52:52Disposable ballpoint pens come with a little secret of their own.
00:52:56Did you ever notice that in some of them, there's a small hole in the plastic part?
00:53:01It's actually a rudimentary ventilation system.
00:53:04It's supposed to let the ink easily make it to the tip of the pen.
00:53:08Okay, I know it's in the name, but you really don't need to shake the seasoning shaker to get any
00:53:14product out.
00:53:15Don't believe me?
00:53:16Hey, you're not the only one.
00:53:17Go grab your favorite seasoning bottle out of your pantry.
00:53:21If it has one of those removable plastic caps, it's perfect for the experiment.
00:53:26Instead of shaking the bottle, try holding it from the plastic cap while it's upside down.
00:53:32Now, gently twist the bottle from side to side and, before you know it, you get some gorgeously flowing seasoning
00:53:39without having to wiggle the shaker and make a mess all over the stove.
00:53:43On the same note, most salt and pepper shakers should have ridges on the bottom of the glass portion.
00:53:50In case you get any seasoning stuck in there, place the bottom of the salt shaker against the bottom of
00:53:55the pepper shaker and wiggle it around so the ridges click with each other.
00:54:00The seasoning should easily pour out now without you having to open the bottle.
00:54:04In colder weather, you often have so many clothing layers on you that you can hardly feel the purse or
00:54:11back straps on your shoulder anymore, not to mention how fast they can slide off.
00:54:16Some jackets come with a built-in solution for that, in the form of a small tab on the shoulder
00:54:21with either a hook or a button.
00:54:23It's meant to be opened and closed comfortably, so you can keep your purse in place at any time.
00:54:30You're most likely using it merely to peel the skin of potatoes, carrots, or cucumbers.
00:54:35But you can use your vegetable peeler for chopping fine strips of onion as well.
00:54:40Just cut the onion into quarters vertically and then start slicing.
00:54:45This might also help out with those embarrassing onion tears.
00:54:49Most people miss this one, but should you ever have a closer look at your toothpaste tube,
00:54:54You will surely see some sort of coloring there, either a dot or a block.
00:55:00Colors can vary. They can be black, green, red, or even blue.
00:55:04These color spots are actually meant to help the assembly machines back at the toothpaste factory.
00:55:09They recognize when and where these machines need to cut the toothpaste tubes and proceed to fold them for packaging.
00:55:16For most types of footwear, if there's anything that seems a bit out of place, always know that it's there
00:55:22for a reason.
00:55:23Most manufacturers don't put extra items on shoes just for fun.
00:55:27It would definitely be a waste of time and resources.
00:55:30For footwear, like boots, for example, there's often a small loop at the top back of the shoe.
00:55:36It's there to help you when you need to put the shoe on, since you can quickly pull on it.
00:55:41Plus, you can also hang the shoe somewhere, most likely to dry, since most boots are meant to be worn
00:55:47in the colder weather.
00:55:48Now, I've been guilty at least once of overdressing with a bunch of layers, just so I won't need to
00:55:54jam everything in my check-in bag.
00:55:56But does it become a problem when you actually have to get seated?
00:56:00What do you do with your coat or your jacket?
00:56:03Well, have a closer look next time you board a plane on the seat in front of you.
00:56:08The hook that keeps the tray table upright can double as a jacket hook.
00:56:12As long as you don't need to have any meals while in the air, you're good to go.
00:56:17Now, most mascaras expire within 3-6 months, I'm told, depending on the manufacturer.
00:56:23But you can help speed up that process if you're not careful enough.
00:56:28Continuously pumping the mascara wand, trying to mix in the product, actually pushes more air into the tube.
00:56:34This can make it dry much faster, and you evidently won't get the desired results with it anymore.
00:56:40There's an easy way to check if your mascara is still good enough to use.
00:56:44If you don't hear a popping noise when you take the brush out, you may very well need to go
00:56:50get yourself a new mascara tube.
00:56:52Now, I know we're living in the era of Bluetooth-connected devices.
00:56:57But for better quality sound, they still recommend using headphones that connect via audio jacks.
00:57:03Remember seeing black ridges on those jacks?
00:57:06They aren't there just to make them fit when you plug them into your phone or laptop.
00:57:10Made out of a special insulating material, these bands are meant to guard the wires when sound is being transmitted.
00:57:18Based on the number of bands, you can figure out which end goes where.
00:57:22Some empty space under noodles in a cup doesn't mean the company producing them wants to cheat you out of
00:57:28a full portion.
00:57:29No, no.
00:57:29It's a manner of keeping the noodles intact during their transportation.
00:57:33It also helps with the circulation of hot water that is poured over the products before you can enjoy them.
00:57:40The V-shaped neckline was initially designed to serve a bunch of objectives.
00:57:44First, as a way of prolonging the life of the garment that would maintain its shape over the years.
00:57:50It's also there to fit your head through the shirt in case it needs some stretching.
00:57:54This way, it ensures a snugger grip around the neck.
00:57:57Lastly, it helps absorb sweat in case you're wearing the shirt while exercising.
00:58:03Now, it's not necessarily a custom anymore, but you may have stumbled upon a dinner jacket with an additional mysterious
00:58:10pocket on the right side.
00:58:12Turns out, this pocket was used by men to easily reach their train tickets, since most of them had to
00:58:18travel to work every day.
00:58:20It helped them keep their jacket buttoned up, but also benefited from the use of a pocket.
00:58:25Now, it's only added as a decoration, and it doesn't serve an actual purpose anymore.
00:58:30Speaking of things we don't use these days, or at least for their initial purpose, did you know Play-Doh
00:58:37was originally a cleaning product?
00:58:39In the 1920s, the market was in need of a product that could help them wipe the wallpapered areas around
00:58:45coal-burning furnaces.
00:58:47The recipe for what we now know as Play-Doh was thus invented.
00:58:51It was manufactured in white only, and was supposed to clean wallpaper by being rolled back and forth over the
00:58:58dirt.
00:58:58It was only later, in the 1940s, that new products for cleaning wallpaper were brought up, and Play-Doh was
00:59:05redirected toward another area of the market.
00:59:09Now, while I enjoy a nice piece of toast for breakfast, isn't it pesky to have to clean out the
00:59:15toaster?
00:59:15Well, not anymore, since I recently found out that toasters have a slide or a panel at the bottom that
00:59:22helps get rid of all those annoying breadcrumbs easily.
00:59:28Now, there used to be a time when you could only have access to video games by inserting cartridges in
00:59:34your console of choice.
00:59:36These tiny objects gave many doctors a lot of headaches.
00:59:39People soon started popping up in hospitals after swallowing small game cartridges, especially the younger generation.
00:59:47Nintendo, the company that manufactures the majority of these devices, had to come up with a creative solution to prevent
00:59:54these accidents.
00:59:55So, these days, Nintendo Switch cartridges are purposely coated with specific chemicals that can leave a really bad bitter taste
01:00:03in the mouth.
01:00:04Not that I'd, you know, recommend you ever try and taste for yourself.
01:00:08Hmm.
