00:00Now, if you're as watchful as I am, you've probably noticed those zigzag patterns on the edges of some packages,
00:06like bags of chips or chocolate bars.
00:09It's clear that they're there to make it easier for you to tear the plastic.
00:12But why does it tear so easily?
00:15Now, plastic is made of long molecules called polymers.
00:19You can compare it with a fabric made of long threads.
00:22But the scale is much smaller, and these strands aren't actually woven together.
00:27What ridges do is remove the support of the surrounding polymer fibers.
00:32When the edge is flat, the molecules are surrounded and kind of protected by their mates.
00:37But if the edge is uneven, molecules on the peaks of the ridges are much more exposed to mechanical damage.
00:44Plus, such an uneven edge allows you to apply more force to a specific point, the groove.
00:50And once that point fails, the groove moves to the next point, causing more tearing.
00:55And this process continues until you stop applying the force, or until you're done tearing the packaging apart.
01:02But this isn't the only packaging secret.
01:05I'm about to reveal the most unexpected packaging facts.
01:09Now, is this what the future of packaging looks like?
01:12A Swiss company has invented a magic juice box.
01:15It's made of agar-agar seaweed gel and water.
01:19It can only contain short-term smoothies and juices.
01:22The box also withers at the same rate you consume the product inside.
01:27Wow! Doesn't it sound like the future is here?
01:30That overwhelming smell of coffee that literally hits you once you open a jar with instant coffee?
01:36This scent is actually just a coffee aroma sprayed onto the lid.
01:40It's done to provide you with the enticing smell of freshly ground coffee.
01:45One of Korea's leading manufacturers of instant noodles has come up with innovative packaging for their production.
01:52It can be safely used in microwaves.
01:54The company claims that some additional material used in this packaging can remain intact without melting, even at high temperatures.
02:02Well, it'll definitely make the process of heating up your lunch much faster.
02:07Now, almost all food we consume has an expiration date.
02:12But this rule doesn't apply to water.
02:14Hmm.
02:15But how come there's an expiration date on every water bottle?
02:19There's no paradox here.
02:20This expiration date refers to the bottle, not the water inside.
02:25They say that regardless of the brand, all chips have a best before date that ends on a Saturday.
02:32It's because a production week starts on a Sunday and correspondingly ends on a Saturday.
02:38Well, I've checked my stash and it seems to be true.
02:41Go look at yours and write in the comments what you found out.
02:46Bubble wrap was originally designed to serve as textured wallpaper.
02:49It was invented in 1957 by engineers Mark Chavons and Alfred Fielding in New Jersey.
02:56They sealed together two shower curtains trapping inside a smattering of air bubbles and wanted to sell the resulting product
03:04as an innovative kind of wallpaper.
03:06Unfortunately, the product turned out to be a failure as wallpaper.
03:10Then the inventor started selling it as greenhouse insulation.
03:14But it wasn't until 1961 that the material's protective qualities were discovered.
03:20And the first client that used bubble wrap as a packaging material was IBM.
03:25This company used it to protect its big IBM 1401 mainframe computer during shipment.
03:32Now, people love personalized products.
03:35According to researchers, a whopping 52% of online customers are more willing to repeat their purchases from a company
03:42when they get personalized shipping boxes.
03:45If you've ever seen someone unboxing Apple products,
03:48you probably noticed that the company used very laconic packaging.
03:53This probably made you think that they put no effort into it.
03:56But that's not true.
03:57To achieve such a level of perfect simplicity,
04:01Apple has created a real culture around its packaging.
04:04The company's headquarters even have a special place
04:07where they come up with packaging designs for new products.
04:10The egg carton was designed in 1911 by newspaper editor Joseph Coyle from British Columbia.
04:17The main goal of this invention was to resolve a dispute between a local farmer and a hotel owner
04:23who kept complaining that the farmer's eggs were delivered broken.
04:27So, necessity is the mother of invention.
04:31Nike has created a shoebox made completely out of recycled trash materials,
04:37mainly drink containers.
04:38This box also allows its owner to wear it as a backpack.
04:43Now, paper packaging for food goes all the way back to China,
04:47to the 2nd century BCE.
04:49At that time, food was often wrapped in thin sheets of mulberry bark.
04:54And later, the idea spread all over the world.
04:57And in 1879, one accident literally changed history.
05:01A worker from a paper bag factory in Brooklyn set the machine he used to the wrong settings.
05:08And instead of creasing small bags, it cut through them.
05:12When the owner of the factory readjusted the settings on the machine,
05:16he realized that it could cut and crease at the same time.
05:19This led to the appearance of mass-produced paperboard boxes.
05:24Now, researchers have found out that the process used during the manufacturing of cardboard boxes can ward off germs.
05:31Hear me out.
05:31To make cardboard, they shape layers of paper and bond them at a temperature of up to 200 degrees Fahrenheit.
05:38That's hotter than most harmful bacteria can withstand.
05:42That's why cardboard boxes are a rather safe way to package foods.
05:46After all, they come out of the manufacturing process sanitized,
05:50even when they're made of recycled materials.
05:53That little open jar icon on cosmetic packaging is the PAO, period after opening symbol.
06:01It informs consumers about the period of time a product may be used after the package is unsealed.
06:07The symbol, featuring a number followed by the letter M for months,
06:11can be seen on almost all cosmetic products.
06:14Some plastic milk containers have dents on their sides.
06:18These dents serve several purposes.
06:20For one thing, when the milk spoils, this process usually causes swelling and high-pressure buildup inside the container.
06:28That's when the dent comes in handy.
06:30It pops out and doesn't let the jug blow up.
06:33Plus, if you decide to freeze the milk, it will expand like any other liquid.
06:38And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
06:45Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
06:51That's because soda contains carbon dioxide.
06:54It's a gas that can expand once the bottle is heated.
06:57If there's no gap in the bottle, it can break because of the pressure building inside.
07:03Also, when you open your drink, the gases go out in the form of bubbles,
07:07and the drink is likely to overflow.
07:09The gap helps with this problem, too.
07:12Now, about those horizontal lines on plastic bottles.
07:16They help hold bottles up.
07:18Some bottles are produced from soft plastic.
07:21Without the lines, they wouldn't keep their shape.
07:23Instead, they would twist easily or even break.
07:27Number 57 on a Heinz ketchup bottle has nothing to do with the product label.
07:32The truth is that the place with the numbers is the very sweet spot you should tap to get the
07:38ketchup flowing.
07:39So, stop smacking the bottom of your sauce bottle and tap the 57.
07:44By the way, if you've been wondering why the number is exactly 57, not 34 or 89,
07:51this comes from the historical advertising slogan, 57 Variety,
07:55created by the Heinz Company located in Pittsburgh, USA.
07:59This advertising campaign told customers about the numerous products manufactured by the company.
08:06Now, at first sight, everything is obvious about plastic lids on disposable cups.
08:10To keep your beverage inside, right?
08:13But that's not all they're capable of.
08:15As soon as you find a cozy spot and get ready to sip on your drink,
08:20you can use the lid as a coaster.
08:22If you look carefully, you'll notice special ridges that hug the bottom of your cup snugly.
08:27It's a snugly hug.
08:29The size of each lid fits the bottom of the corresponding cup.
08:36And the soft round part under a soda bottle cap keeps the carbonation from escaping.
08:42Without it, your pop would go flat in no time, probably even before you buy it.
08:50Road and construction workers are usually dressed in orange because the bright orange hue is visible even in bad weather.
08:58It's the most effective color to attract attention and alert people.
09:01No wonder lots of safety jackets and traffic cones are orange as well.
09:05The stop sign has an eight-sided shape to help drivers recognize it easily, even if they see it from
09:11the back.
09:11And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing the stop sign with any other
09:18at night.
09:19The rumble strips on the side of the road are placed there to alert drivers who doze off behind the
09:24wheel.
09:25When their tires move over these strips, the noise and vibration work like an alarm clock.
09:30There are magnetic locks on fuel hoses at gas stations.
09:34They come in handy if someone drives away with the gas nozzle still attached to their car.
09:39In this case, the lock detaches the hose automatically.
09:42Oh, that's embarrassing.
09:44Gasoline looks like a rainbow in a puddle because it can't mix with water.
09:48It forms a thin membrane over it.
09:50When light reflects from it and the water at the same time, you've got a rainbow.
09:56A triple handle on a jerry can is there to make it easier for two people to carry it and
10:01distribute fuel evenly.
10:03Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.
10:08The air passage will prevent it from pouring out, so no more fuel waste.
10:13Most gas cans have two holes with caps, a bigger and a smaller one.
10:18You're supposed to uncap the smaller hole before pouring gas inside the bigger one.
10:22It'll prevent the liquid from glugging and spilling all over your clothes and the ground.
10:27Another little thingy we often neglect is a point on an ointment cap.
10:32Most tubes are usually sealed with a plastic film or a foil, and opening it with your fingernails isn't the
10:37best idea.
10:38A point easily opens even the most safely sealed tube.
10:43You can use most screwdrivers together with a wrench to create more torque.
10:48Just place the wrench over the handle of the screwdriver.
10:51This way, you'll need to apply a lot less force than before.
10:55You'll also be able to get to hard-to-reach areas more easily.
10:59They install cameras in shops, banks, and hospitals to monitor everything.
11:04If something happens, you can call the police or rescuers.
11:08The camera really helps to solve a lot of problems.
11:10Why are there no cameras on planes?
11:14The crew keep order on the plane, but they won't be able to do anything if something serious happens.
11:19Besides, there's nowhere to run on the plane.
11:22During the flight, the cameras are useless.
11:24And after the flight, the words of the passengers work ideally instead of cameras.
11:29So, if cameras do no good, then why spend money on them?
11:34Water is great at cleaning stuff because it has triangular molecules.
11:38They're made of one oxygen and two hydrogen atoms.
11:41Um, H2O?
11:42Such molecules have slightly different charges on their opposite sides, pretty much like magnets.
11:48That's why water easily sticks to other molecules, including those that make up dirt.
11:53Lots of private houses have triangular-shaped roofs because this allows rain, snow, and fallen leaves to slide off the
11:59slope.
12:00If all this stuff piled up on top of your house, one day, your roof would collapse.
12:06When a storm is coming, clouds seem to turn dark, but it's just an illusion.
12:10Thin clouds on a sunny day let the light through easily.
12:14They also scatter all the colors of the light spectrum.
12:17This makes us perceive the clouds as white, but the thicker the clouds are and the more water droplets they
12:23contain,
12:23the less light they let through and the darker they look.
12:27A good doorknob is the one made of brass, bronze, or some copper alloys.
12:33These metals have an anti-germ effect.
12:36Bacteria spread way slower on them.
12:38They also get rid of germs pretty fast, within a couple of hours.
12:42Nope, it doesn't mean you don't have to wash your hands.
12:46Diamonds have such symmetrical shape to show you their brilliance.
12:49Initially, the gems aren't so beautiful.
12:52They go through several stages of cutting and then become pieces of elegance.
12:57Most of these stones have a round shape with slightly pointed corners.
13:01Diamonds shine the brightest in this shape.
13:05Why are there two holes in the socket?
13:07The left hole is neutral.
13:09The right hole is not.
13:10And the gap underneath is ground.
13:13Electricity needs to flow through the chain.
13:15The current flows from the hot slot, passes through your phone charger, for example,
13:20and then goes through the neutral hole.
13:23Ever wondered what that small pocket on your jeans is for?
13:26People used to wear watches on chains.
13:28That small pocket was meant for it.
13:31Now, almost no one wears such a watch, but the pocket remains.
13:35You can still keep something small in there, like a ring.
13:38In London, there are some poles that look like street lamps, but there are no bulbs.
13:43Well, their official name is stink pipes, and they're a thing of the past now.
13:48But they used to come in handy back in the 19th century.
13:51These hollow poles would vent away the air and explosive gases with bad smells to prevent,
13:56shall we say, unwanted consequences.
14:00Most kitchen shears have metal plier-like teeth in the middle.
14:03Between the handle grips, they can help you crack nuts, crab shells, and other tough products.
14:09You can also open jars and bottles or remove herb stems with their help.
14:14Leather often looks dull to the eye because it's covered with itsy-bitsy scratches and scrapes.
14:19They scatter the light that hits the material.
14:22When you coat your shoes in a layer of wax, you fill these tiny crevices.
14:27The surface becomes smoother, and the rays of light bounce off it more evenly.
14:31That's why the leather looks shiny.
14:34Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
14:40Yellow and light green hues are the most popular
14:43because they don't prevent you from seeing the text after black and white photocopying.
14:48Photocopiers perceive yellow and light green marks as very pale and don't print them.
14:54They make magnets shaped as a horseshoe because this increases the magnetic force.
14:59Colors matter too.
15:00The blue part indicates the south pole.
15:02The red part, the north pole.
15:05The two poles work simultaneously and increase the attraction force.
15:09The dime-sized holes in elevator doors is actually a keyhole.
15:14If the doors get stuck, an operator can open them manually thanks to this hole.
15:19They'll just insert a special key.
15:21The tiny hole in the airplane window is there to balance air pressure.
15:26The window has three layers.
15:28The outer pane is extremely sturdy.
15:31It can withstand air pressure differences during takeoff and landing.
15:35The inner pane, which is the closest to you, is made of cheaper materials.
15:39It prevents potential damage to the window.
15:41The hole itself is in the middle pane.
15:44It not only balances the pressure, but also prevents the window from fogging.
15:50Escalator brushes are there for your safety.
15:52They don't allow you to come too close to the edge of the escalator.
15:55This way, your clothes won't end up between the steps.
15:59You see the sun as yellow or orange.
16:02Because the atmosphere of our planet scatters such colors as blue, green, and violet.
16:07This is also why the sun looks warmer at sunrise and sunset.
16:12Go shopping for some oranges and I'm sure you'll get them in a red mesh bag.
16:16You'll rarely see them lying around without one of those.
16:19It's pure marketing, and that color isn't a random choice.
16:22When packed in a red mesh bag, oranges appear more orange, fresher, and more appealing to you.
16:29So, you're more likely to buy them, right?
16:31Lemons are usually sold in green mesh bags for a similar reason.
16:35If you pack them in red, they'll appear more orange.
16:39Green goes better with yellow, and makes those lemons stand out.
16:43Mattress manufacturers make a limited number of different mattresses.
16:47And the only way to make them look different is to come up with a fancy stitching pattern.
16:52Two mattresses of two different companies might be the exact same quality, but cost differently.
16:57Most people will never know it, and will decide that different patterns mean something in terms of quality.
17:02So, when shopping, don't mind the pattern at all.
17:07Almost all hotels have white bedsheets.
17:09They choose this color specifically to show how high their standards of cleanliness are.
17:14The whiter and brighter the sheets are, the more luxurious the hotel seems.
17:18It's much easier to see dirt and stains on white linen.
17:21It's like proof that you've checked into a clean room.
17:25New iPhone models with large screens have a convenient option called reachability.
17:30Thanks to this function, you don't have to struggle to reach the top of the screen.
17:34This feature can be found in the phone's accessibility settings.
17:38It allows you to lower your screen down.
17:40The rumble strips on the side of the road are there to wake up sleepy drivers who doze off behind
17:45the wheel.
17:46When your tires drift off onto these strips, the noise and vibration work like an alarm clock.
17:52Most kitchen shears have metal, plier-like teeth in the middle.
17:55They allow you to use the device for multiple purposes.
17:58They're placed between the handle grips for you to crack nuts, crab shells, and whatnot.
18:03You can also open jars and bottles with their help.
18:06Some people even use these teeth to remove stems from herbs.
18:09If your audio jack has three rings, it means your device can produce stereo sound,
18:15and your earphones have the microphone function.
18:17The black grating on a microwave oven door is called a Faraday shield.
18:22It stops microwaves from getting away.
18:24If they do, your food won't cook properly.
18:27The digits on an egg can tell you a lot about the product.
18:31In many countries, there's a special labeling system.
18:34The first number indicates the method of production.
18:36The following two-letter code stands for the country where the egg was produced.
18:40And then you can find a registration number.
18:43It indicates the laying hen establishment.
18:45The first number in this code can vary from 0 to 3.
18:490 means it's an organic egg.
18:511. It's a free-range egg,
18:53which means it was produced by a hen that was allowed to wander around outdoors.
18:572. Stands for an egg produced in a deep-litter indoor housing.
19:013. You're about to buy a cage farming egg.
19:04A black band that runs along the edges of your windshield is called the Frit.
19:09It's a baked-in ceramic paint that starts as solid black bands near the edge of the windshield.
19:14Then it dissolves into smaller dots.
19:17The Frit makes the glass rougher, and the adhesive sticks to it better.
19:21The Frit protects the urethane sealant.
19:23It's the substance that fixes the glass to the frame.
19:26It also prevents the sun's ultraviolet rays from melting the adhesive.
19:29As for the black dots, they help distribute the temperature in the car more evenly.
19:35They're aesthetically pleasing, too.
19:37Without them, the contrast between the glass and the dark band would be too obvious.
19:42If you see a pair of jeans with an extra loop, those are special jeans for cyclists.
19:47They're likely to belong to the commuter clothing line, and the loop's main purpose is to hold your bike lock.
19:54Many zipper sliders have outer rings, especially if such sliders are supposed to be used together.
20:00These rings are added so that you can connect the sliders with a lock and keep pickpockets away.
20:06Keyboards come with little legs.
20:08They were designed for you to be able to tilt your keyboard.
20:11This way, you can actually see which keys you're hitting.
20:14At the same time, a flat keyboard doesn't make your wrists so tired,
20:17and people who can type without looking at the keyboard don't need those legs whatsoever.
20:22An olive spoon is usually made of stainless steel and has a small hole cut in its bowl-shaped head.
20:28The main purpose of this utensil is to lift olives, cherries, pickled garlic, and other products from liquid-filled jars,
20:36cans, or bowls.
20:37The hole in the middle allows you to drain the liquid gathering in the spoon fast and easily.
20:42What'll they think of next?
20:44Donuts are shaped like rings because, otherwise, they get overdone at the edges and remain uncooked and gooey inside.
20:51Make a hole in the center, and both the outsides and the insides will be cooked at the same time.
20:56Round-shaped donuts with no holes are usually filled with custard, cream, or jelly.
21:02Such donuts don't have any corners, which means there are fewer weak spots for the filling to spurt out from.
21:09If you grab a full juice box a bit too firmly, you can get sticky liquid all over the place.
21:14To avoid such situations, flip up the tabs on the sides of the juice box.
21:19You can use them to hold your drink.
21:21Some cars have a tiny coffee cup sign on the dashboard.
21:24It's the vehicle's anti-drowsiness mechanism.
21:28Some manufacturers equip their cars with a drowsiness detection system.
21:32It analyzes the speed, wheel angle, and lane deviations, and figures out if it's time for the driver to take
21:38a break.
21:39If it is, the vehicle makes several audio signals, and the coffee cup sign starts to flash.
21:45Produce stickers on fruit and veggies you get at the supermarket are full of information.
21:49If there's a four-digit code on the sticker, the product was grown conventionally.
21:54In most cases, it also means that pesticides were used in the process.
21:58If the product is organic, its sticker has five digits, and the first one is nine.
22:04Genetically modified products also have a five-digit code, but the first number is eight.
22:10Sugar used to be sold in sugar loaves.
22:13Those were tall, hard cones.
22:15At those times, to get sugar ready for tea, people had to use special hammers to break a loaf apart
22:21first.
22:22After that, they cut the sugar into smaller and more nicely shaped lumps.
22:26Only in the middle of the 19th century, people invented the first press that cut sugar into cubes.
22:32This way, the product was easier to store and transport.
22:35A little hole in the end of your wrench can provide your screwdriver with some extra torque.
22:40Just slide the end with the hole over the screwdriver.
22:43You can also use this method when the angle is awkward.
22:46While driving, when it's already dark, you might get blinded by the headlights of the car moving behind yours.
22:52If you have a manual rear-view mirror, find a tab at the bottom and flip it.
22:57The mirror has a reflective material behind its glass.
23:00By flipping the tab, you change the angle of this material, dimming the lights in the mirror.
23:05Most ice cream scoopers come in different colors.
23:08It has nothing to do with aesthetics.
23:11The color indicates the size of the scoop.
23:13This way, you can easily figure out how many scoops you'll need to fill 32 ounces.
23:18Wow, a 32-ounce sundae!
23:20Sign me up!
23:21Some caps on small tubes are hollow on top and have a little spike inside.
23:26Its purpose is to break the foil sticker sealing the tube.
23:30The neck fits right in this hole, and the spike is designed to break the seal.
23:34This way, you don't need to tear the tiny foil seal off with your fingers.
23:38The letter R in a circle on the product's packaging means that the trademark is officially registered.
23:45Once it's done, the trademark's owner has the right to place this letter on all their products.
23:50They can also sue anyone who tries to use their trademark.
23:53A gas pump usually has a small metal latch or hook on its handle.
23:58That's a trigger lock.
23:59You can use it to lock the handle in the open position.
24:02Then the gas will keep pumping even if you walk away.
24:06Coins used to be shaped randomly or have no shape whatsoever in the past.
24:10Dishonest people used it to their advantage.
24:13They stole valuable metals the coins were made of by chipping their corners off.
24:17It was illegal, and to prevent this kind of fraud, round coins were invented.
24:22After that, it became easy to instantly notice when a coin had been fiddled with.
24:27Those two holes in a lollipop stick are there to hold the candy in place.
24:32When the stick is dipped in hot liquid syrup, it flows into the holes and solidifies.
24:36Now, your suite is there to stay.
24:39Fabric squares that come with clothes are for you to try out your cleaning products on them first.
24:44This way, you won't ruin the entire item once you decide to wash it.
24:49The holes in the bottoms of earphones allow air to circulate up and through the speakers.
24:54It helps to increase low frequencies, making the bass sound deeper.
24:58The sound quality also becomes much better.
25:00Don't I sound better? Thank you.
25:02You can adjust your stapler so that it staples documents together only temporarily.
25:07It's done by rotating the crimp area.
25:10Most staplers have two options for stapling.
25:13One is standard, but the other side bends staples away from the center.
25:17Later, when you don't need them anymore, you can easily remove them by hand.
25:21If you store peanut butter jars upside down, the oil will move to the bottom, and all the solids will
25:28be on top.
25:28Hey, don't laugh. That matters to some people.
25:31You don't want to get caught with your peanut butter down.
25:37So get this.
25:38An extra hole at the upper part of the sink has multiple hidden functions.
25:42First, in case someone forgets to close the tap, the water won't overflow and the bathroom won't get flooded.
25:48Second, thanks to that hole, the water drains faster and it gives an escape for the air, helping the water
25:53flow down.
25:55Those two holes on a side of any Converse shoe are not only to let the stinky air out.
26:01Sure, breathability is important for any athlete.
26:03The second reason is that athletes lace through those holes to get a better grip.
26:10Donuts have a hole in the middle and it doesn't stand for O in donut.
26:14It's not designed for an easier grip either, though it can be quite convenient.
26:18It's actually made this way for mass baking, so that they can cook all the way through evenly.
26:25Baby carrots are tiny and, unlike regular carrots, wet.
26:29Baby carrots aren't some special sort of carrots.
26:31They're actually made of regular carrots by cutting off the skin and outer layers and then polishing them to look
26:37that pretty.
26:38The problem is that they can't retain moisture.
26:41A regular carrot retains some water inside because of the layers that locks it in.
26:45Once they're chopped out, baby carrots can dry out easily.
26:48So they usually sell them in bags with some water inside.
26:53Toy stores are filled with Beanie Baby plush toys.
26:56And a detail that is even more iconic than their huge eyes is their tags, saying TY.
27:02That's a small manufacturing company not so many people have heard of.
27:05Beanie Babies appeared in 1993 and they went insanely popular.
27:10TY is the name of the company, but it's not an abbreviation.
27:13It's the actual name of the company's founder, H. Ty Warner.
27:19Most metallic zippers have a hidden lock inside them to save you from awkward situations, such as an undone fly.
27:26Oh boy.
27:27Don't leave the zipper handle in an upward position.
27:30When you pull it downwards, it automatically locks.
27:32It's all thanks to those tiny grooves hidden underneath the handle.
27:38Almost any public toilet has a large gap between the floor and the door.
27:42The reason for such a zero-privacy thing is to actually minimize the level of privacy and comfort,
27:48so that people wouldn't stay there long and there'd be no lines.
27:51It's also easier to clean, and safer if some emergency occurs.
27:58Headrests in a car are about comfort, and detachable headrests are about safety.
28:03If you pull the headrest out of a seat, you'll see two bars, which are quite sturdy.
28:08If you ever get locked or trapped in a car, you can get out of there smashing the window with
28:13these bars.
28:17Many cups and mugs have little grooves on the bottom on purpose.
28:20They're designed for dishwashing machines.
28:22Sometimes, the grooves let the water flow and not spill over your feet when you take the cup out.
28:27Also, those grooves let the air flow so the cup doesn't crack even if the tea is scalding.
28:35Almost all measuring tapes have a metal tip with a small slot on the end.
28:39You can use this slot to hang the tape on a nail or a screw to make measurements without anyone's
28:44help.
28:46Sometimes, this tip has a row of sharp points along the edge on one side.
28:50That comes in handy when you want to leave a mark without using a pencil.
28:55Doorknobs are usually made of brass, bronze, and some other copper alloys for a reason.
29:00They have an antibacterial effect, so they stop microbes from spreading.
29:05They get rid of a range of harmful germs pretty fast within a couple of hours.
29:10But don't forget to wash your hands anyway.
29:14Grocery carts have loops for a reason.
29:16You don't want to put your jacket in a cart next to potatoes and onions.
29:20Hang it on a loop.
29:22This little hook-like thing is there to help you better organize the space in your cart.
29:26The carts also have a super handy grid.
29:29Whenever the cart's full, you just need to lift the grid and attach the shopping basket for extra purchases.
29:34Placing it in between the horizontal bar above the wheels and the hooks the grid has.
29:41A point in an ointment cap is there for a reason too.
29:45Most tubes are usually sealed with foil, and it's better to avoid opening it with fingers unless you're ready to
29:50say goodbye to your nails.
29:52A point easily opens even the most safely sealed tube.
29:58Silica gel can often be found in different things you buy like bags, shoes, and many others.
30:03Don't throw it away.
30:05It's meant to absorb excess moisture.
30:07So anytime your shoes are a bit wet, just throw in a packet with silica gel.
30:13People used to co-live with rats, and these guys like gnawing on everything they see in their way, including
30:19paper.
30:21Still, rats weren't able to chew more than the space left on the margins.
30:27That black grate on a microwave isn't just some fancy decoration.
30:30It's called a Faraday shield, and it prevents the rays from escaping the microwave.
30:35It also speeds up the heating, so you can enjoy yesterday's leftovers faster.
30:40It may also block phone signals.
30:42So if you're tired of numerous calls, just put the phone into a microwave.
30:46But don't turn it on.
30:50All Tic Tac containers are designed to dispense one Tic Tac every time you open it.
30:55The lid has the same shape as the candy.
30:58Turn the container upside down, gently shake it, and open it slowly.
31:01You'll notice only one candy stuck between those lid grooves.
31:05So if you just open the container and shake it until five or even more candies fall into your mouth,
31:10it means you've been eating Tic Tacs wrong all this time.
31:17Those little holes in the airplane windows are designed to control the cabin pressure.
31:21They also protect the windows from fogging up as the temperatures drop and rise.
31:25By the way, the airplane window is round for a reason.
31:28This way, pressure is evenly distributed so it doesn't get deformed.
31:35Blue bristles on a toothbrush are actually an indicator that it's just about time to change the brush.
31:40As the bristles get in contact with water, the blue, or whatever other, pigment fades away.
31:45So the more you use it, the duller the color becomes.
31:50A triple handle on a jerry can is there to make it easier for two people to carry it and
31:54distribute the fuel evenly.
31:56Gas cans often have a second hole that actually needs to be unkept too before you pour the gas.
32:01The air passage will prevent it from pouring out, so no more fuel waste.
32:07Jeans first appeared in 1873.
32:10They were invented by Jacob Davis and Levi Strauss.
32:14Davis was a tailor who was producing covers and tents,
32:17and Strauss was a businessman who, among other things, was selling cloth.
32:22The first jeans were made by Davis from denim, the fabric he bought from Levi Strauss and co.
32:29Together, they patented the design.
32:31Blue was a standard color for denim that was dyed using an indigo dye.
32:36The blue color is a tradition that is still often followed today to replicate the original look of a pair
32:41of jeans.
32:42Jeans also have metal rivets, and they've been there from the very beginning.
32:46Jacob Davis, the man who made the first pair of jeans,
32:49added copper rivets to spots where pants were more likely to rip,
32:53flies and pockets to make them stronger.
32:55Today, they have more of a decorative purpose since they're distinctive and traditional for jeans.
33:02Another special thing about jeans is those tiny pockets they have that seemingly serve no purpose.
33:08Well, maybe it's true now, but years ago, when many cowboys were wearing jeans,
33:12the pocket was made specifically to keep a pocket watch there.
33:16Also, back then, a pair of jeans had just four pockets.
33:19That tiny pocket, the watch pocket, two big pockets in front, and just one pocket on the back.
33:27Many zippers have the letters YKK engraved on them.
33:31It's an abbreviation that stands for the name of the company that can be translated as
33:36Yoshida Manufacturing Shareholding Company.
33:39This Japanese company is the largest zipper manufacturer in the world,
33:42so they put their initials on all the zippers they produce.
33:45That's around half of the zippers in the world.
33:48And that's why you see their zippers more often than any other zippers.
33:54Those little white golf balls have dimples all over them.
33:57It turns out they aren't there just randomly.
33:59At first, golfers were playing with a smooth ball.
34:02With time, the ball would get all punched and damaged,
34:05but also, it would start to travel way further.
34:07The reason here is aerodynamics.
34:10Dimples allow the air to flow more smoothly around the ball, taking it further.
34:15So the idea was adopted, and the balls got their dimples all around,
34:18allowing them to travel longer distances.
34:22Feel like it seemed to long, for a minute to leave it there.
34:22you can see that because you're not here.
34:22I don't know where this technique makes any lie.
34:22Remember this ćcast ass is gonna come up.
34:23Hyades come up your nerves here.
