00:00:00So 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.
00:00:13Second, thanks to that hole, the water drains faster as it gives an escape for the air helping the water
00:00:18flow down.
00:00:20Those two holes on the side of any Converse shoe are not there only to let the stinky air out.
00:00:25Sure, breathability is important for any athlete, but the second reason is that athletes lace through those holes to get
00:00:32a better grip.
00:00:34Donuts have a hole in the middle, and it doesn't stand for O and donut.
00:00:38It's not designed for an easier grip either, although it can be quite convenient.
00:00:43It's actually made this way for mass baking, so that they cook all the way through evenly.
00:00:49Most metallic zippers have a hidden lock inside them to save you from awkward situations such as an undone fly.
00:00:56Oh boy.
00:00:58Don't leave the zipper handle in an upward position.
00:01:00When you pull it downwards, it automatically locks.
00:01:03It's all thanks to those tiny grooves hidden underneath the handle.
00:01:08Almost any public toilet has a large gap between the floor and the door.
00:01:12The reason for such a zero-privacy thing is to actually minimize the level of privacy and comfort,
00:01:19so that people wouldn't stay there long and there'd be no lines.
00:01:23It's also easier to clean and safer if some emergency occurs.
00:01:28Spoiled milk emits gases, like most foods when they go bad.
00:01:32A classic plastic milk jug has a concave shape on one side.
00:01:36So, when the gases expand inside the jug, it expands too, and the concave shape curves out.
00:01:43Also, if you want to save some milk for later and freeze it,
00:01:47the jug will expand when the milk gets solid as well, occupying more space in a jug.
00:01:53Headrests in a car are about comfort, and detachable headrests are about safety.
00:01:58If you pull the headrest out of the seat, you'll see two bars, which are quite sturdy.
00:02:02If you ever get locked or trapped in a car, you can get out of there smashing the window with
00:02:08one of these bars.
00:02:10Bath foam isn't only for fun or a nice smell.
00:02:13It also helps regulate the temperature.
00:02:15The bubbles keep the water hot, so you can enjoy a bath a bit longer.
00:02:20Anyway, it works for acrylic bathtubs only.
00:02:23Those made of metal lose heat really fast either way.
00:02:27Many cups and mugs have little grooves on the bottom on purpose.
00:02:31They're designed for dishwashing machines.
00:02:34The grooves let the water flow and not spill over your feet when you take the cup out.
00:02:39Also, those grooves let the air flow, so the cup doesn't crack even if the tea is scalding.
00:02:45Almost all measuring tapes have a metal tip with a small slot on the end.
00:02:50You can use this slot to hang the tape on a nail or a screw and make measurements without anyone's
00:02:55help.
00:02:56Sometimes, this tip has a row of sharp points along the edge on one side.
00:03:01That comes in handy when you want to leave a mark without using a pencil.
00:03:06Doorknobs are usually made of brass, bronze, and some other copper alloys for a reason.
00:03:11They have an antibacterial effect, so they stop microbes from spreading.
00:03:15They get rid of a range of harmful germs pretty fast, within a couple of hours.
00:03:20But don't forget to wash your hands anyway.
00:03:24Grocery carts have loops for a reason.
00:03:26You don't want to put your jacket in a cart next to potatoes and onions.
00:03:30Hang it on a loop.
00:03:31This little hook-like thing is here to help you better organize the space in your cart.
00:03:36The carts also have a super handy grid.
00:03:39Whenever the cart's full, you just need to lift the grid and attach the shopping basket for extra purchases.
00:03:45Placing it in between the horizontal bar above the wheels and the hook the grid has.
00:03:51A point on an ointment cap is there for a reason, too.
00:03:55Most tubes are usually sealed with foil, and it's better to avoid opening it with fingers unless you're ready to
00:04:01say goodbye to your nails.
00:04:02A point easily opens even the most safely sealed tube.
00:04:07A pack of cotton pads has those strings on it so that we could hang it on some hook or
00:04:12holder.
00:04:12And no, there's no need to untighten and tighten the pack again.
00:04:17Look at the bottom of the pack.
00:04:18It has a perforated line.
00:04:20Tear along it, and now you're good to pull out a cotton pad.
00:04:24If you've ever tried a Nintendo cartridge to taste, you'll confirm that they taste revolting, leaving a sour, bitterish aftertaste
00:04:33in your mouth.
00:04:33They're covered with denotonin benzoate, one of the most disgusting flavors ever known.
00:04:40Actually, this taste is kind of a hidden function.
00:04:42It prevents people from swallowing those cartridges.
00:04:46Silica gel can often be found in different things you buy, like bags, shoes, and many others.
00:04:52Don't throw it away.
00:04:53It's meant to absorb excess moisture, so anytime your shoes are a bit wet, just throw in a packet with
00:05:00silica gel.
00:05:02Escalator brushes aren't for keeping your shoes clean or polished.
00:05:06It's for our safety.
00:05:08Brushes won't let you come close to the edge, so a long coat or bootcut jeans won't end up between
00:05:14the steps.
00:05:16Rough edges on the dimes aren't just about design.
00:05:19The coins used to be made of precious metals to show their real value.
00:05:23People would shave off the edges, spending the shaven coins with the same value, and melt the edges into new
00:05:29coins.
00:05:30To avoid it, minters added that pattern so people could tell if someone cut that coin before.
00:05:36Ever notice a tiny hole on the bottom of a padlock?
00:05:40Its hidden purpose is to drain water to help avoid corrosion.
00:05:43It's always the most convenient place to lubricate a padlock.
00:05:47A drop of oil in there will make it open and close easier.
00:05:52Bottles have long necks for a reason.
00:05:54Hold the neck, not the bottle, if you want to enjoy a cold drink.
00:05:59Same goes for fancy glasses.
00:06:01Their stem saves any drink from overheating.
00:06:04So, hold it right!
00:06:06Notebook margins are not some extra space for note-taking.
00:06:10In fact, people invented them to protect their notes.
00:06:12People used to co-live with rats, and these guys like gnawing on everything they see on their way, including
00:06:19paper.
00:06:20Still, rats weren't able to chew more than the space left on the margins.
00:06:26That black grate on a microwave isn't just some fancy decoration.
00:06:30It's called a Faraday shield.
00:06:32And it prevents the rays from escaping the microwave.
00:06:35It also speeds up the heating, so you can enjoy yesterday's leftovers faster.
00:06:40It may also block phone signals.
00:06:42So, if you're tired of numerous calls, just put the phone into a microwave.
00:06:46But don't turn it on.
00:06:48All tic-tac containers are designed to dispense one tic-tac every time you open it.
00:06:53The lid has the same shape as the candy.
00:06:56Turn the container upside down, gently shake it, and slowly open it.
00:07:00You'll notice only one candy stuck between those lid grooves.
00:07:04So, if you just open the container and shake it until five or more candies fall into your mouth,
00:07:09that means you've been eating tic-tac wrong all this time.
00:07:14Those little holes in the airplane windows are designed to control the cabin pressure.
00:07:18They also protect the windows from fogging up as the temperatures drop and rise.
00:07:23By the way, the airplane window is round for a reason.
00:07:27This way, pressure is evenly distributed, so it doesn't get deformed.
00:07:32Blue bristles on a toothbrush are actually an indicator that it's just about time to change the brush.
00:07:38As the bristles get in contact with water, the blue or whatever other pigment fades away.
00:07:44So, the more you use it, the duller the color becomes.
00:07:48A triple handle on a jerry can is there to make it easier for two people to carry it and
00:07:53distribute the fuel evenly.
00:07:55Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.
00:08:01The air passage will prevent it from pouring out, so no more fuel waste.
00:08:06The tab on the rear-view mirror does have a function.
00:08:10It holds your air freshener, a pair of foam dies, your graduation tassel, and some other useful stuff.
00:08:16But in fact, it works as a tumbler between day and night mode.
00:08:20It helps hold the glare from the car behind you.
00:08:23Those car lights can blind you.
00:08:27Metal buttons on jeans, also known as rivets, helped make the pockets more durable when miners would fill them with
00:08:33heavy tools.
00:08:34They're still helpful today, even if you don't store anything heavy in your pockets.
00:08:38Rivets strengthen the seams and make your jeans last longer.
00:08:43These tiny ridges on the letters F and J on a keyboard help us find the correct keys while touch
00:08:48typing.
00:08:50Also, since they're located in the center, they indicate the optimum position for typing.
00:08:55By the way, QWERTY was invented back in the early 1870s, and before that, the first keyboards were piano-like,
00:09:02with two rows of characters in alphabetical order.
00:09:05Don't blame that little lump on your computer cable for irritating you when it gets stuck somewhere for the umpteenth
00:09:11time.
00:09:11This cylinder—shapes and colors may vary—actually helps prevent interference from other signals, like those your phone emits.
00:09:19A hole in the handle of pots and even frying pans is designed as a holder for spoons if it's
00:09:25large enough.
00:09:26This way, sauce or whatever you stir drops back into the pan, and there's no more mess in the kitchen.
00:09:32As for handles, jerry cans have three of them.
00:09:35It's a smart designer move, so when you carry it alone, you use only the central handle to distribute the
00:09:41weight evenly.
00:09:42But your friend wants to help you out. Each of you grabs the side handle.
00:09:47A lack of privacy in public bathrooms—I mean that significant gap beneath where standard doors tend to be—is there for
00:09:54a reason.
00:09:55This way, people do their business faster, and there are fewer lines.
00:09:59Also, if something goes wrong, it's easy to find a person who needs help.
00:10:04In London, some poles kind of look like street lamps, but there are no bulbs.
00:10:09Well, their official name is stink pipes.
00:10:12And they're a thing of the past now, but they used to come in handy back in the nineteenth century.
00:10:17These hollow poles would take the air and explosive gases with bad smells up to prevent unwanted consequences.
00:10:24Books are printed on large sheets, so one sheet can fit in four printed pages.
00:10:30If a book has an odd quantity of printed pages, chances are you'll get a blank one for notes or
00:10:35the author's signature.
00:10:38Toothbrush bristles have two secret features.
00:10:40First, they fade over time.
00:10:43So when it gets less bright, you gotta buy a new one.
00:10:46Also, the bristles vary in length.
00:10:48And longer ones on one end can help clean the back teeth better.
00:10:54Toothpaste stripes aren't more than a marketing trick.
00:10:56In the 70s, a leading toothpaste brand introduced a blue stripe, claiming their toothpaste had double action.
00:11:03Solid white toothpaste has the same functions, though.
00:11:07Originally, golf balls were smooth.
00:11:10They have a dimpled surface now because players noticed that overused balls with damages flew better than brand new ones.
00:11:16At some point, manufacturers started producing balls with dimples.
00:11:22Windshield black dots, or fritz, help dispense the sun glaring right into your eyes.
00:11:27This frame keeps the UV rays away and helps the glass heat up evenly, so it's sort of sunglasses for
00:11:33your car.
00:11:35The tab on the rearview mirror wasn't meant to hold your air freshener.
00:11:38It's a tumbler between day and night mode.
00:11:41It keeps the glare from other cars at bay, so you can't be distracted by headlights behind you.
00:11:47Color dots on chip bags help manufacturers control the package color and show what ink color was used on the
00:11:53package.
00:11:53No big deal.
00:11:56Your microwave probably has a silence mode.
00:11:59Press 1 or 0 and hold.
00:12:02It might work.
00:12:03Also, there is sometimes a mute button you kept ignoring all this time.
00:12:08Anyway, there are no two identical microwaves, so a manual should come in handy.
00:12:15Grocery cart loops help organize all the stuff in your cart better, so you can enjoy your supermarket trip.
00:12:20You don't want to put your brand new fancy white jacket in a cart next to carrots and onions, huh?
00:12:26Fruit stickers know everything about your apple's past.
00:12:29A five-digit number where the first number is 9 is a good sign.
00:12:33It's an organic product.
00:12:35A four-digit number starting with 3 or 4 means it was conventionally farmed.
00:12:40If the number starts with an 8 and there are 5 digits, it's best to leave it on the shelf.
00:12:47Automatic lip liners and eye pencils have a sharpener installed in the package.
00:12:51The lid on the back part of the pencil doesn't only reveal the color.
00:12:55You can pull it out and sharpen up the product.
00:12:58If you don't feel like peeling an orange, cut it on top and bottom, make a slit on a side,
00:13:04and just pull it open.
00:13:07Toothpicks sometimes have several grooves, and the section with grooves is a makeshift holder.
00:13:12It's easy to break the toothpick into two parts.
00:13:15The smaller one with the groove can be used to avoid contact with the table.
00:13:19You can also make a makeshift stand for disposable sushi sticks.
00:13:23They have a sort of lump at one side before you split the pair.
00:13:27Break that lump off, and when you want to take a sushi break, just place the stick on this stand.
00:13:34Most tubes are usually sealed with plastic film or foil, and opening it with your fingernails isn't the best idea.
00:13:41A point on the ointment tab easily opens even the most safely sealed tube.
00:13:47A dinner jacket has small pockets above regular ones.
00:13:50They're called ticket pockets, and gentlemen wearing such jackets can quickly pull the tickets before getting on a train.
00:13:57Yeah, you've heard before that a drawer beneath your oven is there for keeping the food warm if the guests
00:14:02are running late.
00:14:03Hey, you can also slow cook on lower temperatures in that drawer.
00:14:08All the bottles used to be of the same green color ones, but it turns out brown ones are way
00:14:13better at blocking UV light.
00:14:15Say no more.
00:14:17A dollar has its secrets too.
00:14:20A large letter with a rim shows which bank is responsible for issuing this bill.
00:14:25Twelve different Federal Reserve banks print all the money, so if you want to know where your money comes from,
00:14:30just look for these small codes.
00:14:33A1. Boston.
00:14:34B2. New York.
00:14:37C3. Philadelphia.
00:14:40D4. Cleveland.
00:14:42E5. Richmond.
00:14:44F6. Atlanta.
00:14:47G7. Chicago.
00:14:49H8. St. Louis.
00:14:51I9. Minneapolis.
00:14:54J10. Kansas City.
00:14:56K11. Dallas.
00:14:591112. San Francisco.
00:15:04Rough edges on the dimes aren't just about design.
00:15:07The weight of coins made of precious metal was used to show the coin's actual value.
00:15:12People would shave off the edges, spending the shaving coins with the same value, and melt the edges to make
00:15:18new coins.
00:15:20To avoid it, the Minter added that pattern so people could tell if a coin was cut.
00:15:26Small dimples on the bottom of some cups keep them in place on wet surfaces, and it doesn't let the
00:15:31excess water accumulate while it's in a dishwasher.
00:15:36To enjoy fresh and soft peanut butter, store it upside down.
00:15:40This way, the oils don't stay on the bottom all the time and distribute evenly in the jar.
00:15:45Bath foam has a sort of thermoregulatory function.
00:15:48The bubbles keep the water hot so that you can enjoy your bath a bit longer.
00:15:53Disclaimer. It works for acrylic bathtubs only.
00:15:56Those made of metal lose heat rather fast, no matter how much foam you make.
00:16:01A doorknob made of brass, bronze, and some copper alloys has an anti-germ effect because of its metal properties.
00:16:09A small V-patch right at the bottom of the collar helps put on the sweater without losing any shape
00:16:13over time
00:16:14because it's made of a double layer of webbing material, just like waistbands and cuffs.
00:16:19To avoid spilling juice right onto your t-shirt, try pouring it from the other side of the carton.
00:16:25This way, it sloshes less and it's easy to control.
00:16:30Triangular flaps on small juice cartons can help control unwanted spillage too.
00:16:34If you flip them and use them as handles for the carton, you won't press the package, so the juice
00:16:39won't be squeezed uncontrollably.
00:16:41All the disposable cups look the same.
00:16:44The secret here is the special shape that lets you enjoy your drink easily.
00:16:48The top is always wider for the nose to fit in while you're drinking,
00:16:51and the bottom is always narrower so anyone can hold it, even if the hand is small.
00:16:57Also, the width difference allows the cups to stack.
00:17:01You can use a mason jar directly onto the blender with a screw on top
00:17:05and make any shake you want without having to wash the blender jar.
00:17:08The only rule is to not put your device on max.
00:17:12There is no need to tear one of its edges on stick sachets.
00:17:16The right way is to tear them down the middle.
00:17:18You may say it's not a big difference, but at least there's less mess with those torn paper bits.
00:17:24Two zips for one section can be an excellent pickpocket proof.
00:17:28You can put on a small lock on those zippers and make sure no one but you can open your
00:17:32backpack.
00:17:34If something got stuck in your teeth, it could be hard to have perfect results with loose floss.
00:17:39To increase the tension, tie it in a knot.
00:17:42With increased tension, you'll get rid of that basil between your teeth in no time.
00:17:47A tiny hole on the bottom of a padlock is there to drain water to help avoid corrosion.
00:17:52Plus, it's the most convenient place to lubricate a padlock.
00:17:56A drop of oil in there will make it open and close easier.
00:18:01A tiny plastic disc under a bottle lid is what makes soda sparkling.
00:18:05While the lid keeps the liquid inside, this plastic disc holds the gases inside.
00:18:10Without it, it would just be sweet water.
00:18:13It's a myth that the red side of the eraser is for pencil and the blue one is for ink.
00:18:18The blue one gets rid of mistakes on thicker types of paper only.
00:18:21It works both for pencil and even ink.
00:18:23But make sure the paper is really thick.
00:18:27But that blue little thing can do so much more.
00:18:29It can polish your jewelry, clean your electronics, for example, the screen of your cell phone.
00:18:34You know those irritating sticker residues that won't peel off?
00:18:37Eraser helps there too.
00:18:38So as with cleaning scuffed up suede or dirt you have on your walls.
00:18:43Glass bottles usually have a kind of indent on the bottom called a punt.
00:18:48It's handy for those who pour drinks in the glass.
00:18:51The bottle won't slip from the hands like this.
00:18:54A cotton pads pack has those strings on it to hang on some hook or holder.
00:18:58There is no need to untighten and tighten the pack again.
00:19:01Look at the bottom.
00:19:03It has a perforated line.
00:19:05Tear along it and just pull out a cotton pad from a hanging pack.
00:19:09If you lick a Nintendo cartridge, you'll notice they leave a revolting, sour, bitterish aftertaste in your mouth.
00:19:15They're covered with denotonium benzoate, aka one of the most disgusting flavors.
00:19:20It prevents people from swallowing those cartridges.
00:19:24Bottles have long necks for a reason.
00:19:27Hold the neck, not the bottle if you want to enjoy a cold drink.
00:19:30The same goes for fancy glasses.
00:19:33Their stem saves any drink from overheating.
00:19:35So hold it right.
00:19:38A button on the reverse side of a shirt collar is needed to hold a tie in place.
00:19:43Anyway, slim ties, which this button was designed for, are not that popular today.
00:19:48So this button is only an element of design.
00:19:51All running shoes have an anti-blister system pre-installed.
00:19:55It's the extra hole on top of your sneakers.
00:19:58Make a loop with this hole, inserting the lace in backwards.
00:20:01Cross the laces and insert them into the loops.
00:20:04Then pull the laces down, creating a kind of lock.
00:20:07Some people like to hide the laces under the soles to make them totally invisible.
00:20:13Women's shirts oddly have buttons on the left because some women used to have maids who would help them dress
00:20:18up.
00:20:19It was convenient for maids to button the shirts with the button on the left.
00:20:24Silica gel can often be found in different things you buy, like bags, shoes, and many others.
00:20:30It's meant to absorb excess moisture, so anytime your shoes are a bit wet, just throw in a sachet with
00:20:36silica gel.
00:20:38You are probably using shampoo wrong all the time.
00:20:41Well, the main thing you should know is that you don't apply it directly on your hair.
00:20:45You gotta apply it onto the roots only.
00:20:48The foam that you make is enough to clean your hair.
00:20:52Notebook margins were invented to protect people's notes.
00:20:55People used to co-live with rats, and those rodents nibbled on paper pretty often.
00:21:00Still, they weren't able to gnaw on more than the space left on the margins.
00:21:04Red cups you saw at parties can measure liquids.
00:21:07The bottom line equals 1 ounce, the second line equals 5 ounce, and the third line equals 12 ounces.
00:21:16Detachable headrests in cars are all about safety.
00:21:19If you pull it out of a seat, you'll see two pretty sturdy bars.
00:21:23If you ever get locked or trapped in a car, you can get out of there smashing the window with
00:21:27these bars.
00:21:30A little arrow next to the refueling indicator on the car's dashboard indicates which side of the vehicle has fuel
00:21:36tank openings.
00:21:37It's useful when you need to refuel a rented car.
00:21:42Roadside rumble strips come in handy if someone wants to drive at night, since they prevent falling asleep.
00:21:48Whenever a car bumps into these strips, the driver feels vibration and hears quite a loud noise.
00:21:53So the driver can't help but wake up instantly.
00:21:57Rings used to be more than a stylish accessory.
00:22:00The nobility used rings as a seal.
00:22:03Archers wore rings to protect their fingers from bowstring injuries,
00:22:06while needlewomen from needle pricks.
00:22:10As for rings, three rings on a phone jack are not part of the design.
00:22:14They represent different functions.
00:22:16If your audio jack has three of them, it means your device can produce stereo sound
00:22:20and your earphones have the microphone function.
00:22:24Kings depicted on playing cards are real historical characters.
00:22:27Spades
00:22:28King David
00:22:30Clubs
00:22:30Alexander the Great
00:22:32Hearts
00:22:33Charles the Great
00:22:34Diamonds
00:22:35Julius Caesar
00:22:38We tore off post-it notes incorrectly all this time.
00:22:41If you tear them off from below, they will stick off before long.
00:22:45But if you tear them off on the side, along the sticky line, it will hold on to the wall
00:22:50much longer.
00:22:52A lint roller is good at removing those tiny fibers, but you can also use it to clean other stuff.
00:22:58For example, when you want to remove the dirt from the utensil tray in your dishwasher.
00:23:03Simply take your sticky lint roller and put it into each compartment, and all crumbs, dirt, and leftovers, they're all
00:23:09gone.
00:23:11There's a number put on the side of many cosmetic products.
00:23:14It isn't picked randomly.
00:23:15It tells you how long your product will last after you've opened it.
00:23:19Here's why it has an open jar for a graphic symbol.
00:23:24If you prefer to buy the milk in those plastic containers, you've probably seen those big circles on the side.
00:23:29These circles absorb the shock if you drop the milk on the floor, and also give some extra room so
00:23:35the container can expand.
00:23:36That's how you can see if the milk's turned bad without tasting it.
00:23:40It's sometimes irritating when you see you haven't used the entire stick of deodorant.
00:23:45There's a little bit more left, but it's hard to reach it.
00:23:48Okay, the trick is easy.
00:23:50Unscrew the bottom, take a pencil, and force it underneath that moving platform.
00:23:54That way, you'll push what's left of deodorant out.
00:23:58Two flat prongs you can see on standard plugs used in North and Central America make sense.
00:24:04But how about those holes near the tips?
00:24:06Thanks to them, the outlet firmly grips the plug so that it won't loosen or fall out of the socket.
00:24:12The second thing about the holes is that they allow you to wire electric power directly to the prongs,
00:24:17so you don't even have to use classical electrical outlets.
00:24:21So, if you need to get electrical power via direct wires,
00:24:24yep, the holes we got over there make the entire job much easier.
00:24:30Airplane windows have little holes too.
00:24:32And they're one of the essential features for a plane to fly safely.
00:24:36They protect people from outside pressure and generally balance the pressure on the windows when the plane takes off.
00:24:43A pasta spoon has a hole in its handle,
00:24:45which can definitely be helpful when you grab pasta and want to let water drain out.
00:24:50However, it also comes as a good measuring tool since the hole fits around one serving of pasta.
00:24:56If you take a box of aluminum foil, you'll see tabs you can press on the side.
00:25:00They keep the foil straight and prevent it from rolling.
00:25:04It's also easier to tear off some amount of foil thanks to those tabs.
00:25:09Sometimes, things have a specific purpose, but you can always give them more rolls.
00:25:13For instance, if you want to eat some applesauce, but you don't have a spoon,
00:25:17just take the lid, twist the end to turn it into a handle, and make a scoop.
00:25:22Yum!
00:25:24You can train finger agility by catching noodles and rice with chopsticks from the corners of the Asian food boxes.
00:25:31Or you can expand the box and then it will become a plate.
00:25:36According to one theory, funny fluffy hat balls appeared in the 18th century on the caps of French sailors.
00:25:42They were tired of banging their heads against low ship ceilings and ledges and had created these pom-poms.
00:25:49Trailers used to be shown not before movies, but after.
00:25:53Just think about how it's called.
00:25:55The word trailer means trailer to something.
00:25:58To a car, for example.
00:26:01Wood hangers still occupy a large part of the market because cedar wood, which hangers are made of,
00:26:07contains natural oils which repel moths, thereby preserving your things.
00:26:13To see if the boiled egg was fresh or not, just peel it.
00:26:16The more difficult it is to clean, the fresher it is.
00:26:19There's one more egg trick.
00:26:21Try twisting it.
00:26:22If an egg spins steadily, it's boiled.
00:26:25If it spins slowly or not spin at all, it's raw.
00:26:29So, elevator buttons sometimes feature a star symbol or even a minus sign.
00:26:34The star usually identifies the floor with the main entrance or an emergency exit,
00:26:39often the ground floor or lobby.
00:26:41This is particularly useful for visually impaired passengers and is even mandatory in some places.
00:26:47Usually the star is found on the ground floor button,
00:26:50but in some elevator designs, the labels are placed differently.
00:26:54The minus sign generally marks the basement level.
00:26:58Many truck beds have small recessed slots along the sides.
00:27:02These allow you to place 2x6 wooden boards across to create sections,
00:27:07keeping items from sliding around.
00:27:09People who never notice this feature often complain about cargo rolling all the way to the bed,
00:27:14unaware that the bed already allows for simple built-in divines.
00:27:19Some digital services have clever hidden features.
00:27:23On Spotify, for instance, there is a playlist collection created with Barilla
00:27:28that times your pasta cooking perfectly.
00:27:31Different pasta types even have playlists for different lengths.
00:27:35Netflix also has a dedicated fitness category where you can stream workout sessions.
00:27:41Marmite jars may look round, but they actually have flat sides.
00:27:45When the jar is almost empty, it's better to store it on its side.
00:27:49This design makes it easier to scoop out the spread and ensures you use up nearly every last bit.
00:27:56The standard calculator on some iPhones hides a scientific function.
00:28:01Simply rotate your phone while the calculator is open, and the advanced version appears.
00:28:06If you make a mistake entering numbers – I never do, but you might –
00:28:10just swipe left across the screen to delete the most recent digit.
00:28:14Now, if you find your iPhone flashlight too dim or too strong,
00:28:19press and hold the flashlight icon.
00:28:21This reveals a brightness control slider that you can easily adjust the level of light to suit your needs.
00:28:27The tick-tock container isn't only a storage box.
00:28:30Its cap has a small groove that is designed to dispense a single mint at a time.
00:28:36Instead of shaking out a whole bunch, you can use the cap to get exactly one.
00:28:42That extra tray inside a rice cooker has more uses than many expect.
00:28:47Instead of just being for rice, it's actually a steaming basket.
00:28:50You can use it for vegetables, fish, or other foods.
00:28:53People often steam broccoli or carrots this way.
00:28:57Coffee shop takeaway cups may all look the same, but their shape serves several purposes.
00:29:03The top part is wider, making space for your nose as you drink,
00:29:07while the bottom is narrower, so even small hands can get a good grip.
00:29:11The design also allows the cups to be stacked efficiently.
00:29:15Now, a pizza box can be much more versatile than it seems.
00:29:19If you're eating alone, place the lid across your chest as you eat to catch crumbs and toppings before they
00:29:26drop on your clothes.
00:29:27Hey, now they tell me.
00:29:28The lid can also be torn into four to make makeshift plates.
00:29:32And if you have leftovers, you can refold part of the box inward to create a smaller container for storage.
00:29:39An old pillowcase can be repurposed into a wash bag for delicates.
00:29:44Simply place your underwear, stockings, or slips inside.
00:29:48For best results, turn the opening into a drawstring by folding, hemming, and threading a cord through it.
00:29:54Tighten the drawstring before washing, and your delicates will be protected inside the machine.
00:30:00Now, if you ever forget your cutlery at a picnic, dental floss can help.
00:30:05Plain, unflavored floss cuts smoothly through foods like banana bread or soft cheeses,
00:30:10often giving cleaner slices than a knife.
00:30:13Go figure.
00:30:14Toothpicks can also act as small substitutes for forks when serving finger foods.
00:30:20Glasses or sunglasses with frames that feel unusually flexible are built that way on purpose.
00:30:25This elasticity makes them more comfortable to wear and help prevent the frames from breaking or getting loose too quickly.
00:30:33The mesh bags that oranges or onions are sold in don't need to go straight into the trash.
00:30:39Instead, tie them up and use them as handy scrubbers for pots, pans, and kitchen surfaces.
00:30:44They're surprisingly effective for cleaning.
00:30:47Now, Ritz crackers have scalloped edges that are functional as well as decorative.
00:30:52You can actually roll the edge across slices of cheese, cutting them down to perfect size to fit neatly on
00:30:58the cracker.
00:30:59Wow.
00:31:01Kitchen shears often include a small serrated notch where the blades meet the handles.
00:31:06This design allows you to strip herbs like thyme, rosemary, and chives quickly and cleanly,
00:31:12saving the trouble of picking leaves by hand.
00:31:16Plastic milk jugs usually have a concave section in their design.
00:31:19This isn't just for looks. It makes room for expansion.
00:31:23When milk spoils, gases build up inside the container, pushing the concave area outward instead of bursting the jug.
00:31:30The same thing happens if milk is frozen, since it expands as it solidifies.
00:31:36Alright. Grocery carts often have a loop built into them.
00:31:39It's intended for lightweight items like jackets or bags, keeping them separate from your groceries so they don't get mixed
00:31:45in with food.
00:31:47Packs of cotton pads often come with two convenient features.
00:31:50The strings can be used to hang the package on a hook, keeping the pads easy to reach.
00:31:55And instead of untying the strings every time, look at the bottom.
00:31:59There's usually a perforated line.
00:32:01Tear it open once, and you can pull pads out whenever you need them.
00:32:06There's a simple trick to get salt or pepper to pour out smoothly.
00:32:10Take one shaker, flip it upside down, and notice the ridges on its base.
00:32:14Then, rub it against the ridges of another shaker.
00:32:18The vibrations created by the friction will make the salt or pepper flow out more easily.
00:32:24Most headphones, whether wired or wireless, have tiny holes built into them.
00:32:29These are not design flaws. They allow airflow, which is essential for balanced sound quality.
00:32:35By letting the ear circulate, the headphones can produce clearer, more natural audio.
00:32:40Stick-pack sachets are designed to be opened in a clever way.
00:32:44Instead of tearing one edge, the intended method is to tear down the middle.
00:32:48While it might seem like a small detail, opening them this way reduces mess and avoids bits of torn paper
00:32:55getting everywhere.
00:32:57Double zippers on backpacks or bags aren't just for convenience.
00:33:01They can act as a theft deterrent.
00:33:03If you align the zippers together, you can secure them with a small lock, making it harder for pickpockets to
00:33:09access your belongings.
00:33:10As for the tiny fifth pocket in jeans, it was originally designed to hold pocket watches, but it can also
00:33:17serve as a good hiding spot for the key.
00:33:20That small cylindrical lump on your computer or laptop charger cable might seem annoying when it snags on things, but
00:33:27it actually serves a valuable purpose.
00:33:30Ferrite beads prevent electromagnetic interference in two directions, from a device or to a device.
00:33:36The bead prevents the cable from acting as an antenna and receiving interference from these other devices.
00:33:42This is particularly common on data cables.
00:33:45Those on the charger cable reduce electromagnetic interference coming from this cable.
00:33:51Public restroom stalls often had large gaps at the bottom of the doors.
00:33:55While it may seem like a privacy issue, these gaps exist for practical reasons.
00:34:00They encourage people to use the restroom more quickly, helping keep lines shorter, and they also make it easier to
00:34:06check if someone inside needs assistance in case of an emergency.
00:34:11Now, many ointment tubes come sealed with foil or plastic film, which can be frustrating to open with your fingernails.
00:34:18That little point built into the top of the cap is there to puncture the seal quickly and cleanly.
00:34:24Smart!
00:34:26Some automatic lip liners and eye pencils include a hidden sharpener.
00:34:31Check the bottom cap of the pencil.
00:34:33It not only shows the product's color, but can also be removed to reveal a small sharpener inside.
00:34:40Certain toothpicks come with grooves that aren't just decorative.
00:34:44The first groove is intentionally weaker, allowing you to snap the toothpick in half.
00:34:48The smaller piece, often with another groove, can then be used as a stand to keep the pointed end from
00:34:54touching the table surface.
00:34:57All the bottles used to be of the same green color once, but later it was discovered that brown ones
00:35:02are way better at blocking UV light.
00:35:05Ooh, say no more.
00:35:07Last but not least, those wild patterns you see on a bus seat are there for a reason.
00:35:13They're meant to hide dirt.
00:35:15I mean, you can see for yourself.
00:35:16It's obviously easier to conceal that crazy smear of dirt if there's a pattern.
00:35:23You see these blades?
00:35:25They have notched corners to make your cutting experience smoother.
00:35:28Ooh.
00:35:29The front edge notch helps with separating blades during manufacturing,
00:35:34while the trailing edge notch helps the blade glide easily.
00:35:38And a fun fact!
00:35:39That notch on the front also helps you spot unused sections of the blade.
00:35:44Just a little visual indicator to make your life easier.
00:35:46When it comes to silver vs. black blades, they're both made from the same stuff.
00:35:52But black blades are sharper and are better suited for cutting through tough materials,
00:35:56while silver blades strike a balance between cutting power and durability.
00:36:01If you want that extra cutting oomph, go for black.
00:36:05Oh, almost forgot.
00:36:06The only thing those blades aren't meant to cut is food.
00:36:09It has a rust-proofing oil coating, which is not safe for humans.
00:36:15Check this one out.
00:36:16It's totally giving me childhood vibes.
00:36:19Now, I remember my grandma having tomato-shaped pin cushions just like this.
00:36:24And sometimes they would look more like a salad, with a little pepper thrown in there.
00:36:29Well, believe it or not, this salad actually has a purpose.
00:36:32The tomato keeps your pins in place, while the pepper keeps them sharp.
00:36:37Those peppers are filled with sand, which helps keep your pins nice and sharp.
00:36:41And it's not just sand.
00:36:43Crushed walnuts can also be used to keep your pins in tip-top shape.
00:36:49Now, look at this multiple pocket tool and this little hook on it.
00:36:53It's a bit of a mystery, but it's actually pretty handy.
00:36:56I counted at least four different applications.
00:36:59One, you can use it to carry all sorts of awkward stuff, like camping gear or heavy parcels.
00:37:05Two, need to twist some wire or play around with knots?
00:37:08The parcel hook has got you covered.
00:37:11Three, this hook can save the day with those stubborn zippers, like the ones on your luggage.
00:37:17Four, it's great for pretending to be a budget version of Captain Hook.
00:37:21If you know more applications, let me know in the comments.
00:37:26Apple users, with this feature, you'll never get laundry surprises again.
00:37:31Now, I bet you've had this situation at least once in your life.
00:37:35You wash your stuff, and when you take it out of the washing machine, the size seems to only fit
00:37:40your cat.
00:37:41Your iPhone camera can actually translate those funky laundry symbols for you.
00:37:46There are two requirements, though.
00:37:47You must have iOS 17, and your phone must be in English.
00:37:52Take a photo of the care label, go to the Photos app, and see the details of the image.
00:37:57Everything will be automatically decoded and explained to you.
00:38:02Now, many toasters come with nifty removable crumb trays at the bottom.
00:38:07It's super important to give these trays a good clean every now and then to keep your toaster running smoothly
00:38:12and avoid any potential fire hazards.
00:38:15Just pop them out, shake out the crumbs, and you're good to go.
00:38:19Where you shake them out is up to you.
00:38:21Those little compartments on your gas pump aren't just for show.
00:38:25They're actually there to hold your cap while you're filling up.
00:38:28This nifty feature keeps things tidy and prevents any spills or drips on the handle.
00:38:33So, say goodbye to messy refueling experiences and hello to a cleaner pump.
00:38:39Plus, it makes the whole process way more convenient and efficient.
00:38:44Now, I'll bet your oven gets so greasy and dirty sometimes that you can even hear it oink.
00:38:50Just kidding.
00:38:51I know you're a tidy person.
00:38:53Anyway, if you're looking for a way to bring your kitchen cleaning to a whole new level,
00:38:58here's a tip for you.
00:38:59Most oven doors have handy latches that let you pop the door off for easy cleaning,
00:39:05saving your poor back from the strain.
00:39:08When you're draining noodles or potatoes,
00:39:11there's no need to bother transferring everything to a colander in the sink.
00:39:15Just throw the colander right into the pot, hold it down, and pour the liquid out.
00:39:20It makes life so much easier,
00:39:22especially when you want to save that starchy water for recipes.
00:39:26It's a must for authentic pasta, by the way.
00:39:30So, let's say you've snagged this gem at a thrift store a while back for just under a dollar.
00:39:36It's seen better days, serving as an ashtray, but you decide it's time to give it a new lease on
00:39:42life.
00:39:42Here's the lowdown on how to make it shine again.
00:39:46Mix up a solution of boiling water, baking soda, and table salt in a bowl lined with aluminum foil.
00:39:52Let the piece soak for about 15 minutes, and repeat this process three times.
00:39:58In between soaks, gently scrub any rough spots with a microfiber cloth.
00:40:03After the final soak, dry the piece off and rub on some toothpaste, baking soda, and peroxide.
00:40:10Buff out any remaining tarnish with a clean, dry microfiber cloth.
00:40:14Rinse it off, and now your piece is practically gleaming like a mirror.
00:40:20These aluminum foil boxes have nifty little tabs on the sides that make it super easy to grab a sheet
00:40:27without any hassle.
00:40:28It's like a fancy little bonus that makes the product a breeze and ensures you'll have a smooth sailing experience
00:40:35every time.
00:40:37Manual can openers often come with a handy built-in feature, also known as a bottle opener.
00:40:43It's like getting two tools in one.
00:40:45But did you know that this bottle opener actually has another useful function?
00:40:50It can help you loosen those stubborn, hard-to-open jars.
00:40:54Simply lift the lid slightly at a couple of points with the bottle opener, and then watch it as it
00:40:59effortlessly twists right off.
00:41:02Yeah!
00:41:04Okay, I just found that, apparently, you're supposed to save the first and last slices of a loaf of sliced
00:41:10bread for last.
00:41:12It's like a bread hack or something.
00:41:14Apparently, those end pieces help keep the rest of the bread fresher for longer, and you shouldn't eat them until
00:41:19you've devoured the rest of the loaf.
00:41:21So, next time you're making a sandwich, save those heel slices for the very end.
00:41:27Even bread-eating needs a good strategy.
00:41:30Now, look at those blue levers on the top rack of your dishwasher.
00:41:33I was curious about them, too.
00:41:35And it turns out they are actually water bottle sprayers.
00:41:39They help to ensure that your bottles get a thorough cleaning and rinse during the wash cycle.
00:41:45Many vegetable peelers have those little scoops on top for taking out the eyes from potatoes.
00:41:51And here's a cool tip.
00:41:52You can actually use vegetable peelers in both directions to peel faster.
00:41:57But most people just stick to one direction.
00:42:01When using yellow mustard, make sure to push the lid of the bottle all the way open until you hear
00:42:07a satisfying click.
00:42:08This way, the lid will stay securely in place and won't get in the way when you're dispensing the mustard
00:42:14onto your food.
00:42:15It's a simple step that can make your condiment experience hassle-free and enjoyable.
00:42:20So there!
00:42:22You know that little hole at the end of your pot or pan?
00:42:26Well, it's not just for show.
00:42:27You can actually use it as a handy holder for your forks and spoons.
00:42:32Next time you're cooking up a storm in the kitchen,
00:42:34just pop your utensils in that convenient little hole and keep them close at hand.
00:42:41Okay, just a heads-up to remember to switch the direction of your ceiling fan for the changing weather.
00:42:47And to give it a good clean, too.
00:42:49I've seen that a lot of folks found it helpful before to reverse the fan's direction by flipping a switch
00:42:55for different seasons.
00:42:56So this is just a friendly reminder to go ahead and do it again,
00:43:00pushing hot air down and pulling cold air up.
00:43:06When you're chowing down for some pizza, just tear off the top of the box and use it as a
00:43:11big old plate.
00:43:12You can even rip the box in half and fold it to save some leftovers for later.
00:43:17Well, that's it for today.
00:43:19What, you want to know more cool facts?
00:43:21Sure, but you'll have to subscribe and hit the bell to get more videos.
00:43:25I'm waiting. Go ahead.
00:43:31What's hiding inside Coca-Cola cans and regular household batteries?
00:43:36Why do magnets affect breakfast cereals?
00:43:39Do crosswalk buttons actually work or are they just useless decorations?
00:43:44What does that USB symbol really mean?
00:43:48I'm not sure I know the answers to these and similar questions, but I'm eager to learn the truth together
00:43:54with you.
00:43:55Let's find it out.
00:43:57Coca-Cola cans have a secret few people know about.
00:44:01Here's a Coke can.
00:44:02Let's submerge it in a highly corrosive alkaline solution.
00:44:06The aluminum dissolves due to a process known as hydrolysis, and we can see a plastic liner inside the can.
00:44:13It's made from a polymer or epoxy resin and serves as some kind of a protective barrier between the aluminum
00:44:19walls of the can and the rather acidic soda.
00:44:24Despite a popular myth, household batteries don't actually contain liquid, and if you accidentally cut them open, no toxic liquid
00:44:32will spill.
00:44:33Most of them are dry cell batteries, which are made of electrochemical cells.
00:44:37Those convert chemical energy into electrical energy.
00:44:41Larger batteries often house numerous small cells within them, too.
00:44:45Even Tesla vehicle batteries consist of multiple small cells.
00:44:49When combined, they easily provide the necessary voltage.
00:44:55Most toothbrushes have differently colored bristles, but they aren't just pleasing to the eye.
00:45:00Those bristles, often blue, have a functional purpose.
00:45:03They're called toothbrush indicators, and their colors fade as you use the brush.
00:45:08The American Dental Association recommends changing your toothbrush at least four times a year.
00:45:13And by getting paler, these bristles help you figure out when it's time to replace your toothbrush.
00:45:20You'll probably agree that there's no better snack than a pack of chips.
00:45:24Some are flat, others have ridges.
00:45:26Is it just aesthetics?
00:45:28Not really.
00:45:29The main purpose of those lines on some kinds of chips is to help with the distribution of spices and
00:45:34seasonings.
00:45:35In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
00:45:41Plus, the lines make chips crunchier.
00:45:46Now, this one might be a surprise, but some breakfast cereals are magnetic.
00:45:50That's because they're often fortified with iron in the form of a fine powder.
00:45:55Due to the added iron, cereal flakes get attracted to magnets.
00:45:59All this may sound kind of alarming, but in reality, the iron content in the flakes is minimal and doesn't
00:46:05pose any threat to your health.
00:46:07That clear fluid in gel pens is called the ink follower or stopper fluid.
00:46:12The gel in such pens contains pigment particles dissolved in a polymer solution.
00:46:17The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
00:46:23out.
00:46:24Without this transparent fluid, your gel pen wouldn't function.
00:46:28The fluid always stays in one position and doesn't get dissolved with the gel.
00:46:33Neither does it move backwards or flow out of the pen.
00:46:38Many pedestrian crosswalk buttons, namely in New York, are placebo buttons.
00:46:43They do literally nothing when you press them.
00:46:46Originally, they were functional after being introduced in 1964, but today, most of them don't affect traffic lights,
00:46:52which are programmed based on the real needs of the traffic flow.
00:46:57Why do such buttons even exist then?
00:46:59It's a simple psychological trick, providing you with an illusion of control.
00:47:05You might have noticed that movie theater seats are almost always red.
00:47:10This choice isn't random.
00:47:11It has strategic importance, which is rooted in visual science.
00:47:15The thing is, red light has a longer wavelength.
00:47:18It means that it's the first color to disappear in low light.
00:47:22It allows the audience to concentrate better on the screen once the movie begins.
00:47:25Such a design choice enhances the viewing experience by minimizing distractions.
00:47:32Speed bumps are crucial for pedestrian safety.
00:47:35But at the same time, they can seriously increase car emissions due to the non-stop acceleration and deceleration they
00:47:42cause.
00:47:43To address this issue, some cities like London are testing fake speed bumps.
00:47:48Those are optical illusions painted on the road.
00:47:51They look raised from a driver's perspective, but in reality, they're flat.
00:47:56Authorities hope that this approach will slow down drivers without having a negative impact on the environment.
00:48:04Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
00:48:09That's because soda contains carbon dioxide.
00:48:12It's a gas that can expand once the bottle's heated.
00:48:15If there's no gap in the bottle, it can break because of the pressure building inside.
00:48:21Also, when you open your drink, the gases go out in the form of bubbles, making the drink overflow.
00:48:26The gap helps with this problem, too.
00:48:31The USB symbol.
00:48:32Looking like a trident has always sparked multiple speculations about its origin.
00:48:38One popular idea is that it represents Neptune's trident and symbolizes power and adaptability.
00:48:44But there's also a little bit less exciting theory.
00:48:47A man who claimed to have designed the symbol in the 1980s stated that it was supposed to represent connectivity.
00:48:54The large circle symbolizes a computer, while the attached shapes, the circle, the triangle, and square, stand for different outputs.
00:49:04The design of a tennis racket has a specific feature known as the throat.
00:49:09It's an open space below the head of the racket.
00:49:12This space isn't just for storing balls, it also improves the racket's aerodynamics by letting air pass through.
00:49:19It seriously reduces drag during swings.
00:49:23Speaking of tennis, tennis courts are usually built with a north-south orientation.
00:49:28It helps minimize the impact of the sun's position during the game,
00:49:32ensuring that neither player has the sun directly in their eyes.
00:49:37Look closely at a tram's overhead lines, and you'll see that its contact wires zigzag back and forth instead of
00:49:44going in a straight line.
00:49:45That's because all trams have pantographs attached to their roofs.
00:49:50The upper part of the pantograph is gradually worn down by the overhead wire and eventually needs to be replaced.
00:49:56To wear it down evenly, the wire is not installed strictly along the tram's path, but in zigzag patterns.
00:50:05As the tram moves, the pantograph slides along the wire, and it wears down evenly.
00:50:12Those cone-shaped water cooler cups?
00:50:14Their shape is intentionally designed to prevent users from setting the cups down.
00:50:19This allows employees to minimize the risk of spilling water on their desks around various electronic devices.
00:50:25Plus, less material is used to produce cone-shaped cups, which makes the process less wasteful and more cost-effective.
00:50:33It also kind of supports sustainability by encouraging people to drink their water quickly and dispose of their cups immediately
00:50:40after.
00:50:43Most suitcases have two zipper pulls, and it serves several purposes.
00:50:48First of all, if one zipper fails, the other can keep the suitcase closed.
00:50:52Even better, having two zippers allows you to have easier access to small sections of your suitcase without having to
00:50:59open it entirely.
00:51:02And finally, when you have two zippers, you can connect them with a padlock for increased security.
00:51:10Some plastic milk containers have dents on their sides.
00:51:13These dents serve several purposes.
00:51:15When milk spoils, it usually causes swelling and high-pressure buildup inside the container.
00:51:21That's when the dent pops out and doesn't let the jug blow up.
00:51:25Plus, if you decide to freeze the milk, it will expand like any other fluid.
00:51:30And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
00:51:38If you ever had a problem figuring out why fake pockets exist, you need to hear this.
00:51:44The main reason is that if a clothing item has a specific cut or shape, pockets may spoil it.
00:51:50They can alter the item's shape either in the warehouse or already on the retail rack.
00:51:55The solution?
00:51:57Getting rid of the pockets in key areas.
00:51:59Plus, fake pockets are obviously cheaper, and they don't get stretched out.
00:52:05The thermos wasn't actually invented to keep your coffee warm.
00:52:10It was made by a Scottish scientist who wanted a safe place to keep his chemicals at a stable temperature.
00:52:16So, he took two bottles, put the smaller one inside the bigger bottle, and vacuumed out the air between them.
00:52:26Bet you've never heard of corrugation.
00:52:29It's a system that may lie hidden in your pantry right now.
00:52:34Ever notice those bumps on food cans?
00:52:37That's exactly what they're called.
00:52:39And they're not just for aesthetics.
00:52:41First off, they make the can extra strong.
00:52:44That's because they can help it from cracking during the manufacturing process.
00:52:49Plus, these corrugations come in handy during delivery, acting like a shield to make sure there's no spillage.
00:52:57They're also useful in the long run, because they help keep the cans in their original shape.
00:53:02Even when things get too hot or too cold, these corrugations let them breathe a bit.
00:53:07They expand and contract without breaking the metal.
00:53:10You may not notice any cracks on regular cans, but even the tiniest of openings can leave a way for
00:53:17nasty bacteria to get in contact with the food.
00:53:20Not to mention, they create this little air gap.
00:53:24So when you pop the can open, everything slides out smoothly, without you having to put in that much effort.
00:53:30You know what also doesn't require much effort?
00:53:33Hitting that subscribe button and liking this video.
00:53:39You know there's a plant out there that's so eager to reach the sun, you can hear it grow?
00:53:45Rhubarb, just before it's picked from the fields, soaks up all the sun rays it can get to make glucose.
00:53:51After this sunbathing session, it gets transported to dark sheds.
00:53:56Inside, it keeps on growing and uses the stored glucose as fuel.
00:54:01Nothing out of the ordinary so far, but in that dark, cozy, and warm place, rhubarb starts acting weird.
00:54:09That environment pushes the plant to stretch itself out in hopes it will find sun rays again.
00:54:16It happens so fast that you can actually hear the buds and stalks making noise as they pop open.
00:54:24To make sure this process goes smoothly, there's no light allowed.
00:54:29If light hits the rhubarb at this point, it will start photosynthesizing again and go bitter.
00:54:38Speaking of everyday groceries, you might have noticed that veggie bags come with some green stripes.
00:54:44Know that it's a sneaky optical trick.
00:54:47Those stripes fool our eyes into believing the veggies look way greener than they are.
00:54:52And it's not just veggies that get this special packaging.
00:54:56Oranges are often sold in red mesh bags for the same reason.
00:55:01Lemons? They go for yellow or green bags for that same pop of color.
00:55:07If your cooking skills aren't that good and you're just afraid you're going to mess up dinner yet again, stick
00:55:13to mushrooms.
00:55:14That's because they're almost impossible to overcook.
00:55:17Unlike other vegetables that turn into mush when overcooked, mushrooms are way more resistant.
00:55:24They've got this interesting substance called chitin, a molecular structure that works like an armor.
00:55:30So you can cook them forever, they won't burn.
00:55:37Donuts don't have holes in them because it's easier for you to pick them up.
00:55:41If you've ever tried to make them at home, you might have noticed that when you fry the dough, the
00:55:46outside gets done quickly, thanks to the hot oil.
00:55:49If you want the inside to look just as good, you have to keep it in the oil way longer,
00:55:54but then the outside would get too brown.
00:55:58Thanks to that middle hole, the heat gets to both sides equally, cooking up a flawless doughnut.
00:56:06Here's how that small piece of paper makes it into your fortune cookie.
00:56:10First, they bake these cookies flat like pancakes.
00:56:14Then, while they're still warm and bendy, they sneak in those tiny messages.
00:56:19As the cookies cool down, they toughen up and keep their shape, trapping the fortune inside like a tasty time
00:56:25capsule.
00:56:26One legend has it that these Asian treats were initially intended to help people send all sorts of secret messages
00:56:33without causing any suspicion.
00:56:36Here's a little tip for whenever you're buying lunch at a fast food place.
00:56:40Skip the word extra when you're ordering.
00:56:43The moment you speak that term, you're tempting the employees to charge more.
00:56:47Instead, go for something like, a little more please, when you're getting a special burrito bowl.
00:56:56According to a UK study, cheese is the most stolen of foods worldwide.
00:57:01It's estimated that around 4% of all cheese just vanishes from stores.
00:57:07And no, it's not mice doing the stealing, it's people.
00:57:10Why?
00:57:11Because cheese is becoming more and more valuable.
00:57:14The price of cheese is constantly going up, and sneaky thieves are trying to make easy money by simply taking
00:57:21it from the racks.
00:57:22It's not just cheese, though.
00:57:24Other interesting items on the thieving list include fresh meat, chocolate, and seafood.
00:57:32Ferreira, the company behind those luscious jars of Nutella, needs about 25% of the world's hazelnuts every year.
00:57:41So if you think about it, 1 in 4 hazelnuts ends up in a chocolatey jar.
00:57:46The manufacturers get the nuts from Turkey, Italy, and Chile, making sure they get them delivered from both the northern
00:57:53and southern hemispheres to keep things fresh.
00:57:55Nutella's impact on the economy is even bigger than you'd imagine.
00:58:00Because of this demand, the price of hazelnuts went through the roof.
00:58:05In 2014, a frost hit Turkey's hazelnuts, supply got halved, and prices were even higher.
00:58:12Now, even places like New Jersey are trying to grow those Nutella-worthy nuts.
00:58:21When you imagine someone trying to sneak something into space, your first thought wouldn't be a sandwich.
00:58:27But back in 1965, during a Gemini mission, astronaut John Young brought a corned beef sandwich on board, going against
00:58:36NASA rules.
00:58:37He hid it in his spacesuit pocket before blast-off.
00:58:40About two hours into the five-hour trip, he went to the mission commander and offered him this unlawful treat.
00:58:47The commander, being a good sport, took it, and they shared a quick, savory moment.
00:58:52He even put the unfinished sandwich in his own spacesuit pocket to avoid crumbs making a mess of the spacecraft.
00:58:59Meanwhile, the official NASA-approved food was waiting patiently in a box nearby.
00:59:07Surely, radishes aren't your first pick when it comes to salad ingredients, but they have quite an interesting history, too.
00:59:14These mustard, broccoli, cabbage, and cauliflower cousins have been grown and eaten for longer than you'd imagine,
00:59:21even before the Romans were famous in ancient Egyptian times.
00:59:26In fact, radishes were used as currency for the people who built the pyramids, alongside onions and garlic.
00:59:35You'd think the English are champions when it comes to drinking tea, but you'd be wrong.
00:59:41Turkey is, in fact, the tea capital of the world.
00:59:44Every Turk drinks an average of 1,300 cups of tea each year.
00:59:49On a regular day, they're sipping on three to five cups, but when winter hits, they can reach ten cups
00:59:56a day.
00:59:57Locals claim tea is like a social custom for them.
01:00:00It's more than just a hot beverage.
01:00:02It's an excuse to sit down, enjoy the atmosphere, and connect with loved ones.
01:00:07When it comes to types, black tea is preferred.
01:00:10There might be a magical drink hidden in your fridge.
01:00:14It's tonic water, and it might be able to glow in the dark.
01:00:18If you're curious, test it out with some ultraviolet light.
01:00:22The secret behind this glow is pretty simple.
01:00:24Tonic water has quinine, a chemical that lights up under certain conditions.
01:00:31Quinine was used back in the day to treat certain health problems.
01:00:34The stuff was so bitter that some people started mixing it with sugar and soda water.
01:00:39In simple terms, things glow because they absorb light energy, gets all excited, and then releases it as visible light.
01:00:48Quinine in tonic water absorbs and releases energy, making your drink look like it's from a fairy tale.
01:00:57There's an interesting connection between what we hear and what we taste.
01:01:02Scientists investigated and found that people worldwide link certain sounds with specific flavors,
01:01:08and they call it cross-modal correspondence.
01:01:11High-pitched sounds match up with sweet and sour tastes,
01:01:15while the lower, jarring sounds go hand-in-hand with bitterness.
01:01:19If it's staccato, think crunchy, and if it's smooth and flowing, think creamy.
01:01:25Some even found music that can enhance the taste of chocolate.
01:01:29In this study, when people listened to a high-pitched, sweet soundtrack while eating chocolate,
01:01:35they thought it was sweeter than when they'd heard a lower, more dissonant soundtrack.
01:01:39high-pitched soundsります.
01:01:41High-pitched sounds ok.
01:01:42Amen.
