00:00You've just bought a new bottle of oil.
00:02You're taking off the lid and looking at this little cork that you can tear off by pulling the loop.
00:07Take this thing out, but don't throw it in the trash.
00:11Put it back in an upside-down position to control the pour's flow by pressing your finger against it.
00:18Tiny ridges on the F and J keys on the keyboard help your fingers navigate during touch typing.
00:24When your index fingers are on these ridges, you know exactly where other letters are.
00:30The brushes on the sides of the escalators are not for polishing your shoes, but for your safety.
00:36These nylon bristles prevent your laces and clothes from getting inside the escalator's gears.
00:42No, that wouldn't be good.
00:44Most door handles are made of brass.
00:46This type of metal is good for fighting microbes.
00:49Bacteria can't multiply that much on such surfaces.
00:53These public toilets' cubicles don't look private for a reason.
00:58Huge gaps at the bottom were created to make you want to get out of there as soon as possible.
01:03Thanks to this design, there are almost no cubes.
01:06You can use a plastic lid from soda cups as a coaster.
01:10It has the perfect shape to hold your drink and keep a table surface from getting wet.
01:15Don't turn the lid upside down.
01:17Just put it on the table the same way it was on the cup.
01:20If you're stuck in a car during an accident and can't open the doors, you can use bars from the
01:26detachable headrest to break the window and get out.
01:30Remember those small plastic discs under the bottle lids?
01:34This little thing helps preserve vacuum inside bottles, keeping soda in a fizzy state.
01:40You've probably watched food heating in a microwave at least once in your life.
01:45Exciting, I know!
01:46But why do the developers make the door so dark?
01:50This black film is necessary to block electromagnetic fields.
01:53Tiny dots on padlocks next to the keyhole are designed to dry out the moisture if water gets inside the
02:01lock.
02:01Also, if the lock gets jammed or starts to rust, you can pour oil into it through this hole to
02:07fix the problem.
02:09A golf ball is covered with tiny craters for good aerodynamics.
02:14They're called dimples, and this design helps the ball fly further and more evenly.
02:20Some mugs have a little groove at the outside of the bottom.
02:23It helps water flow out and prevents it from accumulating when the cup is in the dishwasher.
02:29Sunglasses were first used not to protect your eyes from the sun.
02:33They used such glasses during Arctic expeditions.
02:36A huge amount of snow can blind you just like a bright flash.
02:40To save their eyes, they came up with these unique glasses.
02:45You can use any t-shirt not only for dressing, but also as a protective layer for your luggage.
02:51Just put your clothes on your suitcase as a cover, and don't waste time plastic wrapping it.
02:56A button on the back of the shirt collar is there to keep your tie under the collar.
03:01Yes, people don't use it as intended because all ties are thinner now.
03:06But this button is still there as a decorative function.
03:09And here's the initial purpose of a tie.
03:12They created it in the 17th century Europe to tighten the collar.
03:16This way, people protected their necks from a strong wind.
03:20Then, they got used to this part of the outfit and made it a must-have accessory for royal gatherings.
03:26Soft pom-poms on hats were first invented several centuries ago.
03:31Sailors use them to avoid hitting their heads against low ship ceilings and ledges.
03:36They make most clothes hangers from cedar wood, since it contains many natural oils repelling moths that love to eat
03:44your clothes.
03:45A light bulb is spherical because such a shape allows the light to distribute evenly.
03:51Also, such light bulbs are cheaper and easier to produce.
03:54Ever found these pieces of fabric and new clothes?
03:58They're not just patches, but also testing subjects to use before washing.
04:03You can put this piece in the washing machine and see what happens to it.
04:07If everything is fine, then you can safely put your clothes in.
04:10Your ceiling fan has two modes of work, winter and summer.
04:15You need to find the switch on it.
04:17Push it up to activate the winter mode and down for the summer one.
04:21In summer mode, the fan pushes the air down.
04:25It pulls the air up in winter.
04:28Most people have this brown plunger in the bathroom.
04:31In movies, they use those to eliminate a blockage in the toilet.
04:35In fact, the plunger is to get rid of a blockage in the sink.
04:38For the toilet, you need another special device.
04:43The extra space under your oven is not for keeping pans and pots.
04:47You can put some dishes there.
04:49The heat of the stove will keep your meals warm.
04:52It's useful if you're waiting for friends late for dinner.
04:57You're taking a pack of popcorn out of a microwave after heating.
05:01See the little hole at the top of the popcorn bag?
05:04You can use it to get rid of small unpopped grains.
05:07Shake the pack over the plate, and all the grains will fall out through the hole.
05:12Almost all people use a travel pillow incorrectly.
05:16Usually, they put two ends forward and lay their heads back.
05:20Try to turn the pillow on the other side.
05:22The arc should be under your chin, and the two ends should be directed back.
05:27Lay your head forward, and your neck will feel way more comfortable in this position.
05:31And you'll get a good nap.
05:34They create magnets in a horseshoe shape to increase their magnetic power.
05:39The blue part indicates the south pole, the red part the north one.
05:43The two poles work simultaneously and increase the attraction.
05:48Thanks to the perfect aviation design, most planes can fly a long distance even without an engine.
05:54In 1268, Roger Bacon made the first written mention on using telescope lenses for optical purposes.
06:03Magnifying lenses inserted in frames were popular for reading, both in Europe and China at this time.
06:09So, it's still a question if the West took it from the East or vice versa.
06:14If you find yourself in the middle of the sea without food, sorry, you can try fishing.
06:20You can use anything for bait.
06:22Your phone, watch, keys, and you can use laces as a fishing line.
06:27Tie the bait and throw it into the water.
06:29And good luck catching the fish that swallowed your phone.
06:32It's going to be a whopper.
06:34You can turn over the tab on a lid of soda cans and use it to hold a cocktail straw
06:40in place.
06:40The blue half of the eraser wasn't originally created to delete the ink.
06:46Initially, the blue part erased inscriptions and drawings on thick paper.
06:50The red part couldn't do it without leaving streets, but the blue one handled this task perfectly.
06:56Most of us tear sticking notes off incorrectly.
07:00Try not to do it from below, but from the side along the licking lawn.
07:04The paper will stick to the wall for longer this way.
07:08Ever wondered what these two holes in the lollipop stick are for?
07:12All the time, you say.
07:14Well, when they put the bar in hot syrup, the liquid flows inside.
07:19It creates a solid attachment for the plastic.
07:22And so it goes.
07:27When you're hungry or peckish, the kitchen is no doubt your favorite place to be.
07:33And you probably think you know your kitchen pretty well.
07:36In actuality, maybe not as well as you might think.
07:40You see, there are quite a few hidden secrets in your kitchen you're likely unaware of.
07:46First, we're going to take a look at something with holes in it.
07:49No, we're not talking about Swiss cheese.
07:52Though, now you mention it, all this kitchen talk is making me hungry.
07:56Instead, take a look at the knives in your kitchen.
08:00You may notice that some of them have holes or dimples across the blade.
08:04You won't just find these features on one type of blade either.
08:07There are quite a few knives in your kitchen that likely have these holes or dimples.
08:12These can include the paring knife, the bread knife, and, of course, everyone's favorite kitchen knife, the chef's knife.
08:20This feature isn't just decorative, though.
08:22There are a few excellent reasons for these holes and dimples.
08:26One of the main reasons is to reduce cutting friction.
08:29Think about it.
08:30Not all foods are easily sliced.
08:33Say you're trying to make a delicious pumpkin curry.
08:36Of course, you've got your main ingredient.
08:37Maybe you want to add some carrot, among other vegetables, all of which are pretty thick and hard to cut
08:43through.
08:44Pick yourself a knife with some holes in it.
08:47Those holes will help reduce the friction between that tough-to-slice food and your blade.
08:52These knives will also be lighter and, therefore, kinder on your wrist if you plan on cutting food for an
08:58extended time.
08:59The holes in your blade mean less steel, which means less weight, so you'll be making cleaner cuts in your
09:06food with ease.
09:08Another use for these holes is to hang your knives up, significantly larger ones that are harder to store in
09:14a drawer.
09:15Having it hung up at arm's length of the kitchen bench for a commonly used knife like a meat cleaver
09:21will also be convenient.
09:24Of course, when you're cutting your food, you want to be doing it so on a chopping board, which, you
09:30guessed it, has a kitchen secret of its own.
09:33You'll notice, in most chopping boards, there's also a hole at the top of the board.
09:38Sure, this can be handy for when you need to carry it around or hang it up in your kitchen,
09:43as you did with your cleaver.
09:44But there's an additional purpose behind this feature, which probably hasn't occurred to you before.
09:50Once you've sliced up your herbs and vegetables, all that delicious flavor you're going to be adding to your dish,
09:56hover the hole at the top of the chopping board over the pot, pan, or whatever it is you're cooking
10:02in.
10:02Take your knife and gently push your ingredients through the hole for a clean transfer from the board.
10:08Give it a try!
10:09A clean kitchen is a happy kitchen.
10:12I'm sorry, I was just cutting some onions.
10:15But did you know there is, in fact, a secret way to cut onions without the tears?
10:20First of all, it's important to know that your onion isn't a hooligan.
10:24That's not why you end up crying when you cut into it.
10:27The onion skin contains amino acids, and when you cut into it, the chemicals produced from the damage you incur
10:34are released into the air and end up stinging your eyes.
10:37Kinda like payback.
10:38The best way to stifle the production of these tear-inducing chemicals is to cool the onion,
10:44either by freezing it or running it under cold water.
10:48Either way, you should now be able to cut through your onion with dry eyes and a smile.
10:53Keep the water running for this upcoming kitchen secret, and we need to fill the ice cube trays next.
10:59It seems almost impossible to refill your ice cube trays without making a complete mess of the water.
11:05But the design of your standard ice cube tray lets you fill it with ease and a dry kitchen bench.
11:11Rather than filling each well one by one, direct the water onto the flat area in between four ice cube
11:18wells.
11:19It'll channel the water evenly into each well without overfilling and splashing over the sides.
11:24If you're after a speedier method of filling your ice cube tray, tilt it onto an angle and run the
11:30water from the top two wells.
11:32The water will run down the tray like a waterfall and fill up each well with speed and relative cleanliness.
11:38Of course, it's still a challenging journey carrying your ice cube tray from the kitchen tap to the freezer.
11:44We haven't discovered a secret for that yet, other than, well, an automatic ice cube maker.
11:50Now, let's get out of the freezer and heat things up a bit.
11:53However, did you know that spicy food isn't actually hot?
11:58At least not in the traditional sense of the word.
12:00A chemical compound in hot peppers called capsaicin tricks your brain into experiencing that burning sensation in your mouth and
12:08throat.
12:09So, no need to worry, you are not really on fire.
12:12Though it may feel like it.
12:15Your first instinct is to probably grab a tall glass of water and wash it down like you're dousing a
12:21house fire.
12:21But you do not want to do this.
12:24The water will only spread the capsaicin around more and make it worse.
12:29Instead, dairy is your secret best friend when you need relief from an overly spicy pepper.
12:35Most milk products contain a procene called casein, which can help wash away the capsaicin.
12:40So, as long as you have a glass of milk handy, go ahead and test yourself by seasoning your meal
12:46with some challenging spices.
12:49Speaking of seasoning, the most common seasoning ingredient to any meal is undoubtedly salt.
12:54But have you ever grabbed the half-full salt shaker, turned it upside down, and despite shaking it and tapping
13:01the bottom, barely any grains come out?
13:06Sooner or later, salt starts to clump together.
13:09It tends to happen because salt absorbs water vapor in the air, and eventually, it can attract enough that the
13:15salt partially dissolves and sticks together.
13:17Well, the secret solution to this has been under your nose this whole time, and you probably never realized it.
13:25Have you ever noticed some grains of rice in the salt shaker on the table at your favorite restaurant?
13:31They're not there to add flavor.
13:33It's done because the rice absorbs water even faster than the salt, keeping the salt dry for longer.
13:40You can do this with the salt in your kitchen, too.
13:42Just add some uncooked long-grain rice to your shaker, and you'll notice your salt coming out of it with
13:48ease from now on.
13:50But now, let's talk about something you might be flavoring with your now-easy-to-use salt shaker, or rather,
13:56what tends to sprout from it.
13:59Potatoes are one of the most diverse foods on the planet.
14:03As Samwise Gamgee once put it, boil them, smash them, stick them in a stew.
14:07But if you don't get around to cooking your potatoes as fast as a hobbit surely would, you'll likely notice
14:14some shoots start to sprout.
14:16Soon enough, your potato looks like something out of a scary alien movie.
14:21It's not an unnatural process, however.
14:24Like most things, reproduction is part of a potato cycle of existence, and sprouting is part of the process of
14:31creating a new potato.
14:34The speed at which your potato starts sprouting its shoots depends on its exposure to light, temperature, humidity levels, and
14:42how long it is left dormant for.
14:44So, if it's been sitting around for a while, it's likely going to have some sprouts.
14:49It's excellent if you plan to plant your potato.
14:52Of course, this is not so much the case if you plan to eat it.
14:55However, a secret to preventing potatoes from sprouting too early is to store them with your apples.
15:03The apple's ethylene gas prevents the sprouting process for longer.
15:07But don't store your potatoes with your onion.
15:10No, they won't make the potatoes cry, but they will have the opposite effect and cause them to sprout.
15:16So, you see, sprouts on a potato aren't nearly as unsavory as mold on bread.
15:21When the bread is fresh, however, one of the most popular uses is to create toast.
15:27Almost every home has a toaster.
15:29Mine does.
15:30It might surprise you to know that there's likely a secret compartment inside your very own toaster.
15:37What's inside the compartment may not be too exciting, but it happens to be a critical feature that not many
15:43people know exists.
15:45It's the crumb tray, where, as the name suggests, all the crumbs and debris from your toast end up here.
15:52To find this hidden feature, you need to look for it between your toaster's upper and lower body.
15:58Now, it's essential to keep this tray clean.
16:00Not only does it keep your kitchen cleaner, but it also reduces the risk of your toaster being a fire
16:06hazard.
16:07Well, that would be crummy.
16:08Those are some unveiled kitchen secrets we bet you never knew.
16:13Now, you're ready to reacquaint yourself with your kitchen and make a meal with all these handy secrets in mind.
16:20Yep, now I'm hungry.
16:24Remember moving around on those scooter boards during gym class?
16:28Or, more accurately, bashing your fingers repeatedly while holding onto the handles?
16:32Somehow, they managed to be designed perfectly to cause the most finger damage as possible.
16:38But, it turns out that we all missed the actual use of these handles on the slides.
16:43Guess what?
16:43They're finger guards, not handles at all.
16:47The plastic loops on the sides of the boards were designed to protect your fingers from the exact walloping that
16:53we all gave ourselves by using them raw.
16:56See, the correct way to hold on is to slide your hands through the hole and grip the base of
17:01the board itself.
17:02This way, you'll block your knuckles from knocking into other boards and obstacles while you're having the time of your
17:08life scooting around.
17:10When you're getting out of the shower and wrapping yourself in a cozy bathrobe, which way are you supposed to
17:16tie it?
17:16This way, right?
17:17With the belt through all the loops tied around your waist?
17:21I mean, that's how all belts work.
17:23Is it a trick question?
17:25Yup.
17:26Bathrobes actually work better tied like this.
17:29Slide the belt through the first two loops on the front and pull it tight.
17:33It's so much easier to wrap it nice and tight.
17:36Look at this division symbol.
17:38I bet you've never put together what the little-known meaning behind the design is.
17:43It's a fraction, but with the numbers replaced by dots.
17:47Makes perfect sense, right?
17:49Why didn't any of us notice it?
17:52If you slice open an avocado but don't use it, there's a way to keep it from going brown.
17:57Store it in a glass of water in the fridge.
18:00It'll last two to three days longer.
18:02When you're microwaving some popcorn for movie night and are about to pour it from the bag into a bowl,
18:08stop!
18:09There's actually a useful feature built into the microwavable bags that barely anyone uses.
18:16Once it's all popped, the end of the bag will have a slight opening.
18:20Before you tear it open wider, tip the bag upside down and shake it.
18:24It's designed to let the pesky, unpopped kernels fall out.
18:27Shake them all out, and you'll have a perfect bowl of popcorn every time.
18:33Sunblock has an unknown use that could come in handy if you ever have a permanent marker on your skin
18:39and a can of Sunblock spray handy.
18:42Just spray it on the marker and wipe off.
18:45There you go!
18:46It also works on hard surfaces like your kitchen tiles.
18:49So the next time you unleash your artistic talent with a Sharpie somewhere you shouldn't, you're covered.
18:56If the batteries in your remote run out of juice, there's a hidden feature to give them a bit more
19:01life.
19:02Take them out and rub the ends together on both sides.
19:05This cleans off the connectivity points and gives the chemicals inside time to redistribute.
19:11This means you've got more time to run to the store to buy more batteries.
19:16Look up! See your ceiling fan?
19:18Okay, if you don't have a ceiling fan, just go with it and imagine you do.
19:22Well, it has a hidden feature that you probably don't know.
19:26It might be a switch on the fan itself or a button on the remote, but most fans have the
19:32ability to change directions.
19:34And there's a reason you really want it to.
19:37In winter, you want it to spin clockwise, which pushes all the hot air from the ceiling down.
19:43In the summer, you want to spin it counterclockwise to pull the cool air that pulls around the floor up
19:49to circulate around the room.
19:51This next one's a huge deal.
19:54Your microwave probably has a silent mode.
19:57Yeah, that's right.
19:58All your 3 a.m. burritos that you heated up with your finger hovering over the stop button to hit
20:03it one second before the timer went off
20:06could have actually been a lot less stressful.
20:09It depends on the mode, but by either pressing or holding the 0 or 1 button, you should be able
20:15to activate the silent mode.
20:17Now, you can microwave to your heart's content anytime.
20:21Those springy door stops at your baseboards that make the boing sound aren't just door stops.
20:27They're also door holders.
20:29By holding them down and opening the door over them, the spring latches onto the bottom of the door and
20:35locks it open.
20:36Yeah, we all miss that one.
20:38Did you know you've probably been putting on your running shoes wrong?
20:43See, there's a small hole at the top where the laces end that's called a heel lock.
20:48Can you guess what it does?
20:50Yeah, it locks your heels!
20:52That way, they don't slip around and give you a blister or slide your sock down, which is just the
20:58worst feeling, isn't it?
20:59So, what you're supposed to do is loop each lace into its heel lock hole, which creates a small loop.
21:05The opposite lace then goes through that loop.
21:08Tie your laces tight, just like you normally would, and whoa, your heels are secure.
21:15Speaking of shoelaces, if you accidentally knot them so well that even you, with your incredible muscles, can't undo them,
21:22there's a common baking ingredient that has a hidden feature that can help.
21:26Yep, you heard me right, a baking ingredient.
21:31Cornstarch can make your gravy thicker, or it can untie stuck knots.
21:35It's so talented!
21:37Just sprinkle it on any knot, coating it completely, and it will slide free easily.
21:42It works on necklaces, ropes, yarn, etc.
21:45It doesn't work on knots in your muscles, though, unfortunately.
21:49But hey, you can always give it a try.
21:51Uh-oh, did you put on your friend's ring without thinking how much smaller their hands are than yours?
21:57And now it's stuck!
21:59Just grab a bottle of Windex, my friend.
22:02Yep, Windex cleans your windows, of course, but it also has a neat little secret talent at removing stuck rings.
22:09A little spritz, and that bling will slide right off.
22:13Cool, huh?
22:13Why has no one ever taught us that?
22:17Let's say you're writing something in pencil, like an exam, but whoops, you forgot your eraser.
22:23Strangely, you didn't forget to bring your bread to the test.
22:27So you've got that, which is all you need to clear up that mistaken answer you just wrote down.
22:33Roll the bread up tightly until it has a texture best described as, well, eraser-like.
22:39Then go at it, erasing like you normally would.
22:43Why have the bread makers been hiding this from us?
22:45This could have been useful in so many situations when I brought bread to my school exams.
22:51If you wear leather jackets, first off, you're cool.
22:55Second off, you're probably missing out on a hidden feature that's not so hidden and is actually in plain sight.
23:02The straps on the top of the shoulders of your jacket aren't just for decoration.
23:06If you unbutton them while you slide on the straps of your bag, you can clip them shut again over
23:12your bag straps, locking them in place.
23:15No matter how many jumping jacks or cartwheels or breakdancing head spins you do, your bag is not going anywhere.
23:23When you need to wrap up some leftovers, tin foil is your friend.
23:27But it also has a place in the laundry room because of this secret use.
23:32Imagine you run out of dryer sheets.
23:34Your clothes come out of the dryer full of so much static that they make your hair stand up straight
23:40like a cartoon evil scientists.
23:42Here's what you need to do.
23:44Crush up two sheets of tin foil into tight balls.
23:47Throw those clothes back in the dryer with the balls and give them another round.
23:52They'll come out static-free.
23:55After you make hard-boiled eggs, they're in hot water.
23:58Some would say boiling hot.
24:00So how do you get them out easily without reaching in?
24:04A whisk!
24:05Push it over the egg and it will pop into the wire cradle.
24:09Now you can pull it right out with ease and comfort.
24:13The colors of the clips on bread bags actually convey a secret meaning.
24:18They're showing you the day of the week that the loaf was packaged.
24:21Blue means Monday, brown means Tuesday, and white means Friday.
24:25Yeah, it's not just random colors.
24:28And most bread brands follow the same system because there's one company that supplies a lot of these clips.
24:35So when picking out the perfect loaf, you can gauge the freshness by the color.
24:41Now here's a trick.
24:43Instead of putting the box grater vertically on top of a plate, put it horizontally.
24:47With no plate underneath, of course.
24:49This way, you won't risk scraping your knuckles because only your fingertips will eventually touch the grater when you reach
24:55the end of the process.
24:57Also, it gives the grater more stability.
24:59When otherwise, you'd have to balance the grater or even hold it in the air with the other hand.
25:04When you're done, or when there's just too much grated stuff on the bottom wall of the grater,
25:09simply turn it on its side to pour the contents into the bowl or plate.
25:14Flowers in a vase would stay fresher for longer if not for the bacteria that breed in the water.
25:19Since copper has some antibacterial properties, dropping a penny into the water will help keep the microbes at bay
25:26and let you enjoy your flowers for that little bit longer.
25:29An easy way to check if your bed linen has dried completely is to put a small mirror in between
25:35the layers for about 5 minutes.
25:37If the mirror has steamed up when you pick it up, it means the sheets are still a bit damp.
25:42Let them dry until the mirror stops getting cloudy.
25:45A damp bed is a lovely breeding ground for fungi and bacteria.
25:50Okay, I'm in.
25:51If you have a not-very-healthy habit of eating in front of your computer,
25:56you'll be surprised at how much crumbs and grime there is inside your keyboard.
26:01Now, you can just turn it over and shake it vigorously, of course.
26:05But that's not very good for any piece of tech, you know.
26:08So, instead, take a post-it note and run its sticky part over the keyboard.
26:13It will collect the little pieces of trash like magic.
26:17Even a better way to do it, though, is to take a slime and stick it to the keyboard.
26:21Then take it away, squeeze it, and stick again in another part.
26:25The slime will fill the entire space between the keys,
26:28and its sticky properties will let it gather every little bit of garbage.
26:33Separating egg yolks from whites is easier using a plastic bottle.
26:37Break the necessary number of eggs into a bowl,
26:40and then take an empty plastic bottle and squeeze it.
26:43Hold the bottle over the yolk and release.
26:46It'll pull in air and the yolk together, leaving the white in the bowl.
26:50Repeat with the rest of the yolks, and you're done!
26:53And that's no yolk!
26:55If you're tired of spitting out the stones when eating cherries,
26:59or want to make a cherry pie, push the stones out with a straw.
27:03Also, many garlic presses have a special tool on their handle
27:06that can be used exactly for that.
27:09Cleaning a blender can be a nuisance if you do it manually.
27:12Instead, fill it with hot water and add some liquid soap or detergent,
27:16then run it for about 10 seconds.
27:18Rinse it afterwards, and it's clean.
27:21Plaster walls can crumble, flake, and spread dust all over the floor
27:25when you hammer nails into it.
27:27Cut a strip of masking tape and stick it to the place you want to hammer a nail in.
27:32The tape won't let the plaster crack and crumble,
27:34leaving the hole neat and clean.
27:37Small scratches and dents on wooden furniture
27:39can be removed with some toothpaste or a walnut.
27:43For toothpaste, rub a pea-sized amount of it into the scratch until it's gone,
27:48then wipe the leftovers with a damp cloth.
27:50For a walnut, take a half of that brain-shaped nut and rub it into the dent.
27:55Then rub the area with your fingers and buff it with a soft cloth.
27:59This'll help the wood absorb the oil from the nut, making the scratch sealed and gone.
28:05The sticky residue on jars left after you removed the stickers
28:09won't be easily removed by water and detergent.
28:12So take some vegetable oil instead.
28:14Soak a cotton pad in it and wipe the sticky surface.
28:17Let it sit for a while and then wash the oil away together with the residue.
28:23If you can't comfortably reach the wick of a candle with a lighter,
28:27hey, take a stick of spaghetti.
28:29Light up its end, and you'll get a burning stick that's easy to use for hard-to-reach places.
28:34Now, next time your razor blade's getting dull,
28:37try rubbing it backwards on a pair of jeans for regular upkeep.
28:41Not while you're wearing them, of course.
28:43Make sure you keep the blades dry, too, or even kept in mineral oil.
28:47That'll stop them from rusting.
28:49Keep all those jelly, ketchup, peanut butter, and mayo fresher for longer in your fridge
28:54by turning the contents upside down.
28:57This creates a partial vacuum inside the container, helping prevent mold growth.
29:02Storing ice cream upside down will prevent freezer burn, too.
29:06To bring your permanent marker back to life,
29:09simply put a few drops of rubbing alcohol into the felt material inside and shake.
29:14Once the felt absorbs the rubbing alcohol for a couple of minutes,
29:18the marker will be almost as good as new.
29:21Now, don't keep throwing away lettuce that goes black too quickly.
29:25Covering it with a dry paper towel and then placing it in an airtight container
29:29will help it keep fresher for much longer.
29:32This goes for any leafy greens you've got leftovers of.
29:35That sharpish bit sticking out of the cap of your favorite cream is there for a reason.
29:41These tubes are usually sealed with foil,
29:43so unless you love breaking your nails trying to open them,
29:46just flip the cap over and push.
29:49Your bobby pins might not stay in place if the grooves aren't facing the right way.
29:54They should always be on the bottom, close to your head.
29:57Still coming loose?
29:58Well, put a squeeze of hairspray right onto the bobby pin before you put it in your hair.
30:03Now, your cotton rounds pack has those strings on it,
30:07so you can hang it on a handy hook in the bathroom.
30:09But there's no need to loosen and tighten it back up every time.
30:13Check out the bottom of the pack.
30:15It has a perforated line.
30:17Tear it open carefully, and you're good to go.
30:20Two zips too much?
30:22Maybe.
30:23But they come in handy as a clever anti-theft device.
30:26Just lock them together.
30:27Now, no one can open your backpack.
30:30Don't have a lock on you?
30:32You can also tie them together with some string, or even just a paper clip.
30:36Anything to slow those pickpockets down.
30:39That tiny little button on the back of a shirt collar is used to hold your tie in place.
30:44Hey, you don't want your tie trying to escape back there.
30:48Shoe manufacturers care about their customers.
30:50So, most running shoes now have a special anti-blister system pre-installed.
30:56Sounds intense, but it's basically just that extra hole on top of your sneakers.
31:01Make a loop with the extra hole, inserting the lace backward.
31:04Cross your laces and put them through the loops.
31:07Now, pull the laces down to lock your foot in place.
31:10Now, run.
31:11Yeah, go ahead.
31:13Car headrests are all about comfort, and detachable headrests are all about safety.
31:18If you pull the headrest out, you'll see two sturdy metal bars.
31:22If you ever get locked or trapped in your car, you can use the bars to smash the window and
31:27get out.
31:29If you've got some pesky parsley stuck in your teeth, try this tip.
31:33It can be hard to get it out with loose floss.
31:36You need more tension, so just tie it in a knot.
31:40It's not an accident that soy sauce bottles have two spouts.
31:43The sauce is liquid, and it flows out of the bottle pretty easily once you turn it over.
31:48Most Asian food lovers have spilled it at least once in a lifetime.
31:52That's why nowadays, restaurants prefer serving soy sauce in special bottles that have two spouts.
31:58This design allows you to control when and how much sauce will come out.
32:02Just put your finger on one spout when you pour the sauce through another.
32:06If you press your finger tightly to the spout, the sauce will stop flowing, and if you remove your finger,
32:12it'll flow again.
32:14And don't forget to ask your server,
32:16Hey, wasabi!
32:18Alright.
32:19A hair straightener is an excellent tool, not only for treating your natural curls, but also for fixing crumpled money
32:26or documents.
32:26You can also use a regular iron for this purpose.
32:29Just make sure you don't turn on steaming mode.
32:32Otherwise, there's a risk of damaging the paper.
32:35Hair bands are good not only for getting your hair done, but also to open a glass jar with canned
32:41food.
32:41Your hands might slip on the tightly closed lid, and if you don't open the can from the first attempt,
32:47your palms tend to get sweaty, making the task virtually impossible.
32:51So, put a hair band on the lid to fix your hand and make your grasp stronger.
32:57A simple rubber band will do as well.
32:59Now, it's time to take my sweaty palms and go.
33:02Okay, listen up.
33:04I'm only going to say this once, unless you back the video up.
33:08You get a small piece of fabric with new clothes, so you can test the material before washing the garment.
33:14If it fades, stretches, or pills in the wash, you'll know and won't ruin the whole piece of clothing.
33:20The spike in the cap of a tube of ointment or cream is there so you can puncture the tiny
33:25foil seal.
33:26No need to grab a toothpick or try to use your fingernails to peel it off.
33:30You can stretch out the pleats of those ketchup cups to get more room.
33:34So, if you like a whole handful of fries or you're trying to dip a chicken nugget, well, there you
33:40go.
33:41Go check your box of aluminum foil.
33:43Does it have push-in tabs on the sides?
33:45They're there to keep the roll in place as you pull some foil out.
33:49Now, flip a stapler upside down.
33:52See the metal plate on the bottom?
33:53You can turn it to get temporary staples, ones whose pins are bent outward and are easier to take out.
34:00Speaking of flipping stuff, do it with a salt jar.
34:03Nah, you should have closed the lid first.
34:05Now you've got salt all over the place.
34:07Okay, now you've done it.
34:09Look at the bottom of the jar.
34:11See the ribs on it?
34:12If you take another jar, say with pepper in it, and rub the bottoms of the two jars against each
34:17other,
34:18the salt will pour out evenly without you having to shake it vigorously.
34:22Same works with pepper, too.
34:24It wasn't their original purpose, but you can use soda can tabs to hang hangers on other hangers.
34:30By the way, the hole in the tab is there to put straws through and keep them in place.
34:35Post-it notes are supposed to be peeled off from the side like you're turning the page in a book.
34:41Most of us tear them from the bottom, and that just creates a crease and makes the whole note less
34:46sticky.
34:47The hole in your spaghetti spoon helps you measure the perfect portion.
34:51It's just enough for one person.
34:53Multiply that by however many people you're serving.
34:56Or maybe you just like to pig out on pasta.
34:59Hey, I'm not judgmental.
35:01Does the audio jack in your headphones have one, two, or three stripes?
35:06One band means your headphones just play sound.
35:09Two means stereo sound.
35:11And three mean the headphones also have a microphone.
35:15To prevent water from boiling over, just lay a wooden spoon across the rim of the pot.
35:20It only works for a little while, though.
35:22If the spoon's surface gets heated up to boiling point, the bubbles will just foam up and around it.
35:28That's why metal spoons won't do.
35:30They heat up too quickly.
35:32Silica gel packets can absorb up to 50% of the humidity in a confined space.
35:37So use them around the house.
35:39Tape one to the lid of a container of dry goods, be it dog treats, breadcrumbs, cookies, you name it.
35:45Throw one in each of your dresser drawers.
35:47Just make sure they don't get accidentally eaten.
35:50Most people use bobby pins upside down.
35:53The zigzag part goes closer to your scalp.
35:56The texture keeps the hair and pin in place much better.
36:00Bubble wrap was originally created as wallpaper that would be easy to clean.
36:05But the decor idea didn't take off.
36:07So they found a new use for it.
36:09Now they help cushion items during shipping.
36:12And they pop so nicely, of course.
36:14Hey, just ask my dog.
36:15All crackers and some cookies have holes to make sure the final product has the right texture.
36:22These teeny tiny holes allow steam to escape, so your crackers and cookies wouldn't snap.
36:27If it weren't for these holes, also known as dockers, steam would build up inside the tree.
36:33And the final result might have been scrumptious, but it would have been rather oddly shaped.
36:38The scalloped edges on Ritz crackers are there so you can roll the cracker over your cheese
36:43so that you get the perfect size piece to sit on top.
36:47It works for soft-dish cheese only.
36:49Don't try to cut some parmesan like this.
36:52Cheesily speaking, you probably grate your cheese with a cutting board or a plate underneath the box grater.
36:59Try a more convenient method.
37:01Flip the box grater and lie it on the side.
37:03This way, you get the finest shreds of cheese and it's mess-free.
37:08PVA glue doesn't stick inside the bottle because it contains long molecules, such as polymers and water.
37:15Once you squeeze the glue out, the water trapped inside evaporates, leaving only sticky polymers.
37:22Super glue doesn't stick inside the bottle because of a special chemical that hardens when it hits water vapor.
37:28So, the glue doesn't stick because the container keeps water out.
37:32The bread goes stale just because it loses moisture.
37:35When you add water to the flour, it changes texture.
37:39And the starch molecules get pretty disorganized.
37:41Hey, I can relate.
37:43That's why bread is soft and fluffy when it's freshly made.
37:46But the more it cools down, the more water it loses.
37:50Starch molecules get their original crystallized state back.
37:53Also, recrystallization happens way faster in the fridge.
37:57The sole of your sneakers, and even the tires of your car, are just one huge molecule.
38:03It's because when rubber is vulcanized, all the molecules become connected through the sulfur.
38:09So, they turn into one, but a really large molecule.
38:12Your jeans are blue on the outside and white on the inside because of a smart way to weave the
38:18fabric.
38:19The warp thread is dyed, while the weft thread has no color.
38:23It's just white.
38:24This way, manufacturers reduce the amount of dye needed for each piece of clothing.
38:29By the way, most jeans are blue because they were originally dyed with indigo dye with a rich blue tint.
38:35This dye was picked for the way it interacted with cotton.
38:39When the cotton is heated, most dyes just penetrate it.
38:42But indigo dye stays attached to the surface.
38:45As a result, each time people wash their jeans, the dye molecules escape the fabric, leaving a unique pattern on
38:52each garment.
38:53Today, manufacturers use synthetic indigo dye.
38:57Bananas have thick skin to keep insects away.
39:00However, it gets thinner as the fruit ripens.
39:03Once the banana is ripe, it starts getting water from its skin.
39:07Birds and animals can also tear the thin skin easily.
39:10Hey, smart move, Mother Nature!
39:13The public toilets tend to be U-shaped for hygienic reasons.
39:17This way, anyone who wants to use it is less likely to get in contact with ceramic, normally swarming with
39:23germs.
39:24The bottled water has an expiration date.
39:27However, the water itself doesn't go bad.
39:30The problem is about the bottle.
39:32The plastic starts releasing chemicals over time, so the water gets contaminated.
39:37You can't drink it anymore.
39:39Glass-bottled water has an almost indefinite shelf life.
39:42Still, some criteria, as changes in room temperature, may lead to a slow increase of bacteria in water.
39:49So, it might go bad, too.
39:51If all else fails, try drinking it from the faucet.
39:54Who would have thought?
39:56Fresh water.
39:57In-flight food is way saltier and spicier than back on land.
40:01Airlines have to give an extra kick to all the dishes due to in-cabin conditions.
40:07The combination of dry air and changed pressure changes how we perceive taste.
40:12Also, the taste isn't only about taste buds.
40:15It's about 80% smell.
40:16But as odor receptors don't work the way they should because of dry cabin air, well, without some extra seasoning,
40:23the food would have been almost completely tasteless.
40:26And yes, I've been known to be completely tasteless myself.
40:30Veins appear blue because they're under our skin.
40:33And skin scatters more blue light than red.
40:36Also, the skin around the veins looks even redder than the veins, enhancing the contrast, and the veins appear even
40:43bluer.
40:44However, it's just an illusion.
40:46Our blood is always red.
40:48Trust me.
40:50Supermarket tomatoes look tremendous but taste bland because, for the past 70 years, farmers have opted for fruits that ripen
40:58more evenly and look better and more pleasing to customers.
41:01Wild tomatoes are dark green and don't ripen evenly.
41:05Still, the tomatoes the farmers grow have a teeny tiny mutation in one gene.
41:10That's why they're evenly colored but can't produce chloroplast properly.
41:14It changes the whole photosynthesis process, leaving the evenly colored tomatoes with less sugar in their tissues.
41:22As a result, these tomatoes tend to taste like cardboard.
41:25The moral to the story appears to be, go get some ugly tomatoes.
41:30Or tomatoes.
41:32The space below, a cup of noodles, is there to protect the noodles during transport.
41:37This technique is called a middle suspension.
41:39This way, they're protected better in their styrofoam cup, and it also helps those noodles soften more evenly and quickly.
41:47Now, chewing gum wasn't invented for keeping your breath fresh.
41:50It was supposed to be a replacement for rubber.
41:53But the rubber experiment failed, giving opportunity to a modern version of chewing gum.
41:59Sandwiches have all their filling in between two slices of bread to keep the hands clean.
42:04Well, at least it was so when the first sandwich was invented.
42:07Some centuries ago, I wasn't around then, the fourth Earl of Sandwich, John Montague, asked his chef to cook him
42:15something yummy he could eat without interrupting his long binge.
42:19The chef, I think he was named pastrami or something, wrapped meat and all the other ingredients in the bread
42:25to make the dish greaseproof.
42:27And finally, all the ingredients in margarita pizza stand for one of the colors in the Italian flag.
42:34Basil represents the green stripe, mozzarella represents the white one, and tomatoes, or tomatoes, represent the red stripe.
42:42And if you want it tastier, use ugly tomatoes.
42:46Linda is an intern at a dental clinic.
42:50She's walking up to her car with a coffee in one hand and a purse in the other.
42:56She takes out the keys, but they fall out of her hands.
43:00She puts the bag on the car's roof, picks up the keys, opens the door, starts the engine, and drives
43:06away.
43:08She pulls out onto the road and realizes she must have left her bag on the roof.
43:13Linda pulls over, gets out, and looks back.
43:16Her purse is on the ground.
43:18Linda's approaching it, but a truck runs over the bag.
43:22Her cosmetics, a cell phone, a book, and everything else is flattened and broken.
43:28Linda gets out a smashed, curved tube of toothpaste.
43:31She squeezes the gel onto her palm.
43:34How is this possible?
43:35There should be a complete mess inside the tube.
43:37But somehow, these three colored stripes didn't mix.
43:41They're running parallel to each other with the same thickness.
43:45Linda decides to find out how it works.
43:48She comes home and puts the toothpaste in the freezer.
43:53After a couple of hours, she takes out the tube and cuts it in half.
43:59She sees a frozen substance with three colors inside.
44:02It seems they put the gel in the tube in this way, with three stripes.
44:07When you squeeze the tube, the paste comes out evenly.
44:11Okay, but why don't these colors mix inside?
44:14Linda finds out there's a whole science studying the deformation and flow of substances in liquid,
44:21gaseous, and soft-solid states.
44:23They call it rheology.
44:25They use this science to create the necessary viscosity and density of toothpaste
44:30to prevent it from mixing inside the tube and turn it into foam as you brush your teeth.
44:35They put toothpaste in the tube from the backside with the help of a special machine.
44:41Different strips inside the tube have the same rheology.
44:45Under uneven pressures, they retain the same thickness and flow.
44:49When at rest inside the box, these strips have a more voluminous shape.
44:54But when you squeeze them, they get thinner as they approach the nozzle.
44:58They're released at the same speed and consistency, no matter how hard you press.
45:03The toothpaste regains the thickness after being pressed.
45:07It's like a marshmallow that returns to its shape after you've smashed it.
45:12Some dental companies equip their product with a small cylinder connected to the nozzle inside the tube.
45:18They fill the pack with white paste and put a small amount of two colorful gels on the sides of
45:24the cylinder.
45:25As you're squeezing out the toothpaste, it's passing through both sides of the cylinder
45:29and pushing the colored gel out of the container.
45:32Then, all of it comes through the nozzle in the form of three stripes.
45:38There are a lot of different patterns of toothpaste.
45:41It can be three stripes or just one color.
45:45But white, red, and blue are the classics.
45:49The white stripe is responsible for whitening teeth and removing the dirt.
45:53This is an essential function of toothpaste, so there's a lot of white gel.
45:58The blue stripe is responsible for fresh breath and protection from germs.
46:03The red color protects and strengthens the gums.
46:07This is not a strict rule, and companies may change the functions of the stripes however they want.
46:13Linda is a little dizzy from all this knowledge, but she seems to understand everything.
46:19She squeezes the toothpaste onto the brush and thinks,
46:23Why does the brush have exactly this length?
46:25And why should the toothpaste cover it completely?
46:28Brushes have various shapes, but their proportions are generally explicitly created for comfortable cleaning.
46:34And here's a little secret about the amount of toothpaste.
46:38You don't need to cover the entire brush.
46:41One little piece size is enough to clean your teeth.
46:44Companies want you to run out of toothpaste quickly to make you buy a new one sooner.
46:50Linda is brushing her teeth and thinking how lucky she is to live in the 21st century.
46:56Toothpaste, dentists, and dentures.
46:58So many different ways to treat and care for teeth.
47:01She can imagine how difficult it was for people long before they invented dental technologies in the distant past.
47:08It seems they all had severe teeth problems and were in pain.
47:12But in fact, they didn't.
47:14Even cave people had much better teeth than we have now.
47:18Archaeologists found evidence of this.
47:21Many ancient skulls have a perfect row of teeth without cavities.
47:25Linda doesn't believe it.
47:27She looks at her electronic toothbrush.
47:29Hmm, those ancient civilizations must have had some secret technologies that we don't know about.
47:35But there were no dental technologies.
47:38To understand how they managed to keep their teeth so healthy, you first need to understand what a tooth is.
47:44On the inside, it consists of dentin, a flexible but durable substance.
47:54The outer part is covered with the most solid material in the human body, enamel.
47:59It's made of calcium and covers each tooth.
48:02And it's not just a strong shield.
48:05Enamel consists of hundreds of thousands of thin fibers called prisms.
48:09One prism is brittle, but a bundle of a million can be as hard as a diamond.
48:15The prisms are closely twisted with each other, like a rope, and form an ideal tooth structure.
48:21That's why teeth are a perfect tool for survival.
48:24Imagine a cave human eating meat and vegetables.
48:27This food is different from steak and salads at a restaurant.
48:31Back then, food was quite dense and solid.
48:34To chew it, you had to have strong jaws and teeth.
48:38Every meal was a real workout.
48:41During chewing, the fibers in meats and vegetables cleaned teeth from dirt and dental plaque.
48:46People had strong gums and didn't know about cavities.
48:50Their teeth were practically invulnerable.
48:53Many years later, we began to use this excellent tool for survival to chew soft buns, hamburgers, tender pâtés, and
49:02omelets.
49:03Teeth no longer received the load they were created for.
49:06That's why they've become weak.
49:09Humanity is faced with a diet that has never existed in the entire history of our planet.
49:14Too little time had passed from the moment when people were chewing on mammoths
49:18to the instant they started ordering tender meatballs at a restaurant.
49:22In simple words, softness has taken over the strongest material in the human body.
49:28Yeah, the teeth became weaker.
49:30But then, another serious problem arose.
49:33Sugar.
49:34Cavities appeared when they first brought sugar to Europe.
49:37This delicacy instantly became popular.
49:40They added it to food and just ate it in cubes like candies.
49:44Sugar was considered a prestigious and expensive thing.
49:48Of course, no one knew that this product would cause tooth decay.
49:52When this problem appeared, people started to create new dental technologies.
49:57There are other destroyers besides sugar.
50:00Your mouth contains a lot of bacteria.
50:03Most of them help digest food, get rid of bad microbes, and clean teeth from plaque.
50:08But there are also harmful germs that destroy teeth structure and form cavities.
50:14In the past, when food was more natural and rugged, these microbes were not dangerous for strong teeth.
50:22Today, we eat food rich in carbs, flavorings, various additives, and sugar.
50:28We help harmful bacteria multiply, making them stronger.
50:31Your lifestyle also affects dental health.
50:35In the past, people had to get food in the fields, forests, and mountains.
50:40They mostly lived an active lifestyle and burned a lot of calories.
50:44Nobody really works like that now.
50:47Training in the gym is much easier than trying to catch a mammoth.
50:51Lack of activity provides calories.
50:53Extra calories and germs create stomach problems.
50:56Gas and acids from the intestine enter the oral cavity and destroy the teeth as well.
51:03Now, just look at these guys for comparison.
51:05Cats, lions, bears, tigers, cows, and other animals with teeth still eat the same way they did millions of years
51:16ago.
51:17And that's why they hardly ever have dental problems.
51:20Many tribes of indigenous people living far from civilization also have perfect teeth.
51:26Linda realizes that all this is true.
51:29And what do we all have to do with that?
51:31Move to a distant island and eat bananas?
51:34Eh, no worries.
51:35It's not that bad after all.
51:37Just eat less sugar, clean your teeth with a brush, and use dental floss twice a day.
51:42Visit the dentist regularly and everything will be fine.
