00:07Before you throw away your next plastic bottle, look directly underneath it.
00:12The strange bumps and seams on the bottom can tell you how it was manufactured.
00:17Now, grab a coffee cup lid, flip it over, and compare the circular ridge with the bottom of the cup.
00:24On some designs, they fit together like a tiny coaster.
00:28Familiar objects are covered in details like these, and once you know why they're there, they're almost impossible to unsee.
00:37Start with the hole in a saucepan or skillet handle.
00:41People online often claim it was secretly designed to hold a wooden spoon above the pan.
00:47On some cookware, that trick physically works, but the reliable purpose is much simpler.
00:53The hole allows the pan to be hung.
00:55That's especially useful for non-stick cookware, because direct stacking can scratch the cooking surface.
01:03If hanging isn't possible, cookware care guides recommend putting a soft separator between pans.
01:09The four-sided box grater may be the most underused object in the kitchen.
01:15Large holes create thick shreds.
01:18Smaller holes make finer pieces.
01:20The long slot slices firm foods, but the weird side covered in sharp stars is effectively a rasp.
01:27It works on citrus zest, garlic, ginger, nutmeg, chocolate, and hard cheese.
01:35Instead of forcing food through the openings, the raised teeth scrape extremely small particles from its surface.
01:41Now, look at your microwave door.
01:45The dark mesh inside the window isn't there simply to make the glass harder to see through.
01:50The holes are small enough that visible light can pass through while the much longer microwave wavelengths are blocked by
01:57the conductive screen.
01:58That's why you can watch your food rotate while microwave energy remains inside the oven.
02:05If the door or seal is actually damaged, however, don't rely on viral flashlight tricks to test it.
02:12The appliance should be inspected properly.
02:15The microwave's rotating plate solves another invisible problem.
02:19Microwave energy forms complex patterns inside the cavity, producing hotter and cooler regions.
02:26Moving the food through those regions helps reduce uneven heating.
02:31That's why manufacturers tell users to rotate or stir food during some cooking cycles, even when the machine already has
02:39a turntable.
02:41Your refrigerator door has a similar invisible design trick.
02:45The flexible gasket isn't merely soft rubber.
02:48Many refrigerator seals contain magnetic material that pulls the gasket against the metal cabinet, helping maintain a consistent seal without
02:58requiring mechanical latches.
03:00That small design choice helps keep warm room air out while making the door easy to open thousands of times
03:07over the appliance's life.
03:09Now, check your keyboard.
03:11On many computer keyboards, the F and J keys have tiny raised bars.
03:16They're physical landmarks for touch typing.
03:20Place your index fingers on those two bumps, and your other fingers naturally fall across the traditional home row without
03:27needing to look down.
03:29Similar tactile markers appear on the number five of many numeric keypads, giving your fingers a reference point without requiring
03:37your eyes.
03:38A fuel gauge can hide an even more useful symbol.
03:42In many modern cars, a tiny arrow beside the fuel pump icon points toward the side containing the fuel filler.
03:50It takes less than a second to check, but it solves the classic problem of driving an unfamiliar or rental
03:56car into a gas station and realizing the fuel door is on the opposite side.
04:02The headrest in a modern car also contains more engineering than its name suggests.
04:08Its primary safety function is to reduce backward movement of the head relative to the torso in a rear impact,
04:16helping limit certain neck injuries.
04:18That's why its height matters.
04:21The restraint is designed to sit behind the head, not down near the shoulders.
04:26Treating it purely as a pillow misses the reason it exists.
04:30Now, look at a disposable plastic bottle.
04:34The bottom often has a raised center surrounded by molded feet, rather than being perfectly flat.
04:40The geometry helps the thin plastic resist deformation and remain stable while using relatively little material.
04:48Carbonated drink bottles need to withstand internal pressure, so their bases are especially engineered to distribute that load, while still
04:57allowing the bottle to stand upright.
04:58Even cardboard packaging can contain deliberate mechanical features.
05:04Foil boxes, for example, may include tabs, closures, or internal geometry intended to keep the package shut and control the
05:12roll.
05:13Packaging has changed over time, so not every viral, secret tab exists on every brand.
05:20But modern manufacturers explicitly advertise easy open and stay closed box design.
05:26And finally, check the cap on a bottle of medicine or household product.
05:32Many child-resistant closures use two motions at once, usually pushing and turning, because a simple screw thread would be
05:41too easy to open accidentally.
05:42Inside, separate surfaces engage only when downward pressure is applied.
05:48What feels like an annoying lid is actually a compact mechanical lock built into something produced by the millions.
05:56That's what makes hidden features so addictive.
06:00Once you remove the fake internet hacks, the real designs are usually better.
06:05A bump can position your fingers.
06:08A microscopic-looking mesh can contain microwave energy.
06:12A tiny arrow can tell you which side of the car to use.
06:16And a few molded ridges can make a thin plastic bottle withstand pressure.
06:21Most of these details aren't hidden at all.
06:23We've just looked at them so many times that we stopped seeing them.
06:31Remember moving around on those scooter boards during gym class?
06:35Or, more accurately, bashing your fingers repeatedly while holding onto the handles?
06:40Somehow, they managed to be designed perfectly to cause the most finger damage as possible.
06:45But, it turns out that we all missed the actual use of these handles on the slides.
06:50Guess what?
06:51They're finger guards, not handles at all.
06:54The plastic loops on the sides of the boards were designed to protect your fingers from the exact walloping that
07:00we all gave ourselves by using them wrong.
07:03See, the correct way to hold on is to slide your hands through the hole and grip the base of
07:08the board itself.
07:09This way, you'll block your knuckles from knocking into other boards and obstacles while you're having the time of your
07:15life scooting around.
07:17When you're getting out of the shower and wrapping yourself in a cozy bathrobe, which way are you supposed to
07:23tie it?
07:24This way, right?
07:25With the belt through all the loops tied around your waist?
07:28I mean, that's how all belts work.
07:30Is it a trick question?
07:32Yup.
07:33Bathrobes actually work better tied like this.
07:35Slide the belt through the first two loops on the front and pull it tight.
07:40It's so much easier to wrap it nice and tight.
07:43Look at this division symbol.
07:45I bet you've never put together what the little-known meaning behind the design is.
07:51It's a fraction, but with the numbers replaced by dots.
07:55Makes perfect sense, right?
07:56Why didn't any of us notice it?
07:59If you slice open an avocado but don't use it, there's a way to keep it from going brown.
08:04Store it in a glass of water in the fridge.
08:07It'll last two to three days longer.
08:10When you're microwaving some popcorn for movie night and are about to pour it from the bag into a bowl,
08:16stop!
08:16There's actually a useful feature built into the microwavable bags that barely anyone uses.
08:23Once it's all popped, the end of the bag will have a slight opening.
08:26Before you tear it open wider, tip the bag upside down and shake it.
08:31It's designed to let the pesky, unpopped kernels fall out.
08:35Shake them all out, and you'll have a perfect bowl of popcorn every time.
08:40Sunblock has an unknown use that could come in handy if you ever have a permanent marker on your skin
08:46and a can of Sunblock spray handy.
08:49Just spray it on the marker and wipe off.
08:52There you go!
08:53It also works on hard surfaces like your kitchen tiles.
08:56So, the next time you unleash your artistic talent with a Sharpie somewhere you shouldn't, you're covered.
09:03If the batteries in your remote run out of juice, there's a hidden feature to give them a bit more
09:08life.
09:09Take them out and rub the ends together on both sides.
09:12This cleans off the connectivity points and gives the chemicals inside time to redistribute.
09:18This means you've got more time to run to the store to buy more batteries.
09:23Look up! See your ceiling fan?
09:26Okay, if you don't have a ceiling fan, just go with it and imagine you do.
09:30Well, it has a hidden feature that you probably don't know.
09:34It might be a switch on the fan itself or a button on the remote, but most fans have the
09:39ability to change directions.
09:41And there's a reason you really want it to.
09:44In winter, you want it to spin clockwise, which pushes all the hot air from the ceiling down.
09:50In the summer, you want to spin it counter-clockwise to pull the cool air that pulls around the floor
09:56up to circulate around the room.
09:59This next one's a huge deal.
10:01Your microwave probably has a silent mode.
10:04Yeah, that's right.
10:05All your 3am burritos that you heated up with your finger hovering over the stop button to hit it one
10:11second before the timer went off could have actually been a lot less stressful.
10:16It depends on the mode, but by either pressing or holding the 0 or 1 button, you should be able
10:22to activate the silent mode.
10:24Now, you can microwave to your heart's content anytime.
10:28Those springy door stops at your baseboards that make the boing sound aren't just door stops.
10:34They're also door holders.
10:36By holding them down and opening the door over them, the spring latches onto the bottom of the door and
10:42locks it open.
10:43Yeah, we all miss that one.
10:46Did you know you've probably been putting on your running shoes wrong?
10:50See, there's a small hole at the top where the laces end that's called a heel lock.
10:55Can you guess what it does?
10:57Yeah, it locks your heels!
10:59That way, they don't slip around and give you a blister or slide your sock down, which is just the
11:05worst feeling, isn't it?
11:06So, what you're supposed to do is loop each lace into its heel lock hole, which creates a small loop.
11:12The opposite lace then goes through that loop.
11:15Tie your laces tight just like you normally would and, whoa, your heels are secure.
11:22Speaking of shoelaces, if you accidentally knot them so well that even you, with your incredible muscles, can't undo them,
11:30there's a common baking ingredient that has a hidden feature that can help.
11:34Yep, you heard me right, a baking ingredient.
11:38Corn starch can make your gravy thicker or it can untie stuck knots.
11:42It's so talented!
11:44Just sprinkle it on any knot, coating it completely, and it will slide free easily.
11:49It works on necklaces, ropes, yarn, etc.
11:52It doesn't work on knots in your muscles, though, unfortunately.
11:56But hey, you can always give it a try.
11:59Uh-oh, did you put on your friend's ring without thinking how much smaller their hands are than yours?
12:04And now it's stuck!
12:06Just grab a bottle of Windex, my friend!
12:10Yup, Windex cleans your windows, of course, but it also has a neat little secret talent at removing stuck rings.
12:16A little spritz, and that bling will slide right off.
12:20Cool, huh?
12:21Why has no one ever taught us that?
12:24Let's say you're writing something in pencil, like an exam, but whoops, you forgot your eraser.
12:30Strangely, you didn't forget to bring your bread to the test.
12:34So you've got that, which is all you need to clear up that mistaken answer you just wrote down.
12:39Roll the bread up tightly until it has a texture best described as, well, eraser-like.
12:46Then go at it, erasing like you normally would.
12:50Why have the bread makers been hiding this from us?
12:53This could have been useful in so many situations when I brought bread to my school exams.
12:58If you wear leather jackets, first off, you're cool.
13:02Second off, you're probably missing out on a hidden feature that's not so hidden and is actually in plain sight.
13:09The straps on the top of the shoulders of your jacket aren't just for decoration.
13:14If you unbutton them while you slide on the straps of your bag, you can clip them shut again over
13:20your bag straps, locking them in place.
13:22No matter how many jumping jacks or cartwheels or breakdancing head spins you do, your bag is not going anywhere.
13:30When you need to wrap up some leftovers, tin foil is your friend.
13:34But it also has a place in the laundry room because of this secret use.
13:39Imagine you run out of dryer sheets.
13:41Your clothes come out of the dryer full of so much static that they make your hair stand up straight
13:47like a cartoon evil scientists.
13:49Here's what you need to do.
13:51Crush up two sheets of tin foil into tight balls.
13:54Throw those clothes back in the dryer with the balls and give them another round.
13:59They'll come out static free.
14:02After you make hard boiled eggs, they're in hot water.
14:05Some would say boiling hot.
14:07So how do you get them out easily without reaching in?
14:11A whisk.
14:12Push it over the egg and it will pop into the wire cradle.
14:16Now you can pull it right out with ease and comfort.
14:20The colors of the clips on bread bags actually convey a secret meaning.
14:25They're showing you the day of the week that the loaf was packaged.
14:28Blue means Monday, brown means Tuesday, and white means Friday.
14:33Yeah, it's not just random colors.
14:35And most bread brands follow the same system because there's one company that supplies a lot of these clips.
14:42So when picking out the perfect loaf, you can gauge the freshness by the color.
14:49Hey, if you're using your phone to watch something and are tired of propping it up and having it fall
14:55back down, try using your sunglasses.
14:59Simply place them upside down and use the parts that go around your ears to hold the phone in place.
15:05You can put old newspaper at the bottom of your trash bags to absorb food juices.
15:10This way, when you come to take out the trash, you don't get that gross liquid dripping on your floor.
15:16If you have flowers that are starting to droop, try placing a copper coin in the water.
15:22Copper is a natural fungicide, so adding a penny to the water helps protect your flowers from bacteria.
15:29This way, your flowers will stay fresh for longer.
15:33You can use the spring from an old pen to stop your charger's wire bending and fraying.
15:39Just take out the spring and wrap it around the top of the wire near the connector.
15:44Moving objects through a door when it keeps closing is super annoying.
15:48So instead, tie a rubber band around the handle on each side of the door so that it crosses over
15:55the latch.
15:56The latch then won't be able to pop out and the door won't lock shut.
16:01You can use a paper clip to find the end of your tape.
16:05Simply place the clip under the end of the tape and you'll never have to hunt again.
16:11To check whether your bed sheets are fully dried, take a mirror and place it underneath.
16:16Leave it there for around five minutes.
16:18And if it steams up, it means the sheets are still damp.
16:22A damp bed can be a breeding ground for mold and other nasty fungi.
16:28Running a post-it note over your laptop keyboard will help get rid of the built-up grime and any
16:34pesky bits of food.
16:36Now wait, you don't actually eat at the computer, do you?
16:40Instead of filling your purse or wallet with store loyalty cards, you can take a photo of them.
16:46Just take one snap of the barcode as well as a picture of the front so you know which card
16:51it is.
16:52Then, when you visit the store, just scan the barcode on your phone to collect your points.
16:57Forgot to put your drink in the fridge?
17:00Wrap a wet paper towel around it and put it in the freezer.
17:04In just 15 minutes, your drink will be ice cold.
17:08You can paint the end of your keys with different colored nail polish so you can easily identify which key
17:15is which.
17:15To stop your wrapping paper from enrolling, you can cut open an old toilet paper roll and use it as
17:22a cup.
17:23In order to pour the perfect amount of oil or salad dressing, poke holes in the foil seal rather than
17:30removing it completely.
17:32This prevents a big amount rushing out quickly.
17:35To prevent band-aids from slipping off your finger, cut a line on either side.
17:41The band-aid, not the finger.
17:43This will create four smaller sticky strips rather than one large one and it will be much easier to secure.
17:50When your candle is burned down and the wick is difficult to reach with a lighter, you can use a
17:56stick of spaghetti.
17:58Just light the end and you'll have a longer stick that burns just as well so you can get to
18:03those hard-to-reach places.
18:05Secure a rubber band over the top of your paint can so that you can wipe excess paint onto it.
18:11This stops paint running down the sides of your can and keeps things neat and tidy.
18:17If you're struggling to get your taco shells to stay in place, use a muffin tray.
18:23Flip the tray upside down, spray it with oil and place your tortillas in the gap.
18:28Cook them for around 10 minutes at 700 degrees for the perfect crispy taco shell.
18:34You can use a water bottle to separate egg yolks.
18:38Hold the bottle over the yolk and squeeze it to suck the yolk up.
18:43Drop it into a separate bowl and you're good to go.
18:47Looking for a lost earring or pin on the floor?
18:50Place a stocking over the end of your vacuum and move it over the floor.
18:55The small object will get picked up without getting vacuumed.
18:59Next time you're struggling to clean your ceiling fan, use a pillowcase.
19:04Slide the pillowcase over each blade to wipe off the dust.
19:08This way, excess dust is caught inside the pillowcase and won't rain down on you.
19:14Poke a straw through your cherries to remove the stems.
19:17It's much quicker and this way you don't waste as much fruit.
19:22If you're struggling to put a bracelet on your own hand, try using a paper clip.
19:27Open up the paper clip and slip it through the loops on the end of your bracelet.
19:32Hold the clip in the middle of your hand with your fingers, then flip the bracelet around your wrist.
19:38You should then be able to easily clasp it shut.
19:42To properly clean your blender, fill it with soap and hot water.
19:46Switch it on for around 10 seconds and let the swirling water do the hard work.
19:51Then just rinse it off and it's clean.
19:55Put down a strip of masking tape before nailing into plaster walls.
19:59The tape should stop the plaster from flaking or spreading dust all over the floor.
20:05When you're heating up leftovers, make a space in the middle with a spoon.
20:09The food will heat up much more evenly.
20:13Avoid the mess and frustration of peeling an orange by slicing off one end of the fruit.
20:18Then cut four to six slices and you'll find the peel will come off much easier.
20:25If you're struggling to use your butter because it's too cold, try using a cheese grater.
20:31Just grate the butter to make your life much easier.
20:34You can make a DIY garden sprinkler using an old plastic bottle.
20:39Punch some holes all over the bottle and then tape it to the end of your hose pipe.
20:44If your shoes smell bad, put a few dry tea bags into the shoe.
20:49The tea bags will absorb the smell.
20:52Potato chips are a perfect fire starter.
20:55The fat, oil and chemicals inside make them super easy to burn.
20:59And yet we still eat them.
21:01Can you see the irony?
21:04Try using toothpaste to remove small scratches on furniture.
21:07Rub a pea-sized amount on the scratch in a circular motion until the scratch buffs out.
21:14Then wipe it with a damp cloth and voila!
21:18Candle wax that's been spilled on furniture can be removed with ice cubes.
21:23Rather than ruining the finish by trying to scrape it off, fill a plastic bag with ice and let it
21:29sit on the wax for a few minutes.
21:31The wax will then cool and harden, making it much easier to pick off.
21:37Drill a couple of small holes in the bottom of your trash can to stop the bag getting stuck when
21:43you pull it down.
21:44The holes stop the vacuum-like effect that keeps the bag pinned down.
21:49Crayon marks on the wall are a parent's nightmare, but you can use a hair dryer to get them off.
21:55Heat the marks for a few seconds to soften the wax and then you should be able to just wipe
22:01it away.
22:02If you don't have the correct size coin to put in your shopping cart next time you go to the
22:07supermarket, you can use your key instead.
22:10If you have a key with a rounded end, you can insert that where the coin would go and the
22:15cart should unlock.
22:16You can easily remove the sticky residue from jars using cooking oil.
22:21Soak a cotton pad in some oil, then rub it on the sticky area.
22:25Allow it to sit for a few minutes, then it should wipe away easily.
22:30Attach a clothespin just under the head of your toothbrush to stop it from falling onto the dirty countertop.
22:37Maybe you should also clean your dirty countertop.
22:41To stop heavy flower pots from damaging your surfaces, stick furniture sliders to the bottom of the pot.
22:48You can use hair conditioner to make that new wool sweater less itchy.
22:53Just soak it in lukewarm water with a couple of tablespoons of conditioner and leave it for 15 minutes.
23:00Then just dry it and your sweater will be much softer.
23:04You can even wear it while you clean your dirty countertop.
23:08If you ever find yourself stuck in the trunk of your car, stay calm.
23:12All cars are supposed to be equipped with an emergency latch to help open the trunk from the inside in
23:18the unlikely case it happens.
23:20These latches are so well thought out that they can be opened by people of all ages.
23:25More so, handles are designed to glow in the dark, too.
23:29You can even pull them with a mouth if there's not enough wiggle room to use your hands.
23:33Never mind how you ended up in the trunk in the first place.
23:36Moving on!
23:37If you're ever working with needle and thread, remember you don't need to stick the needle directly into the spool.
23:44You may end up losing the needle altogether.
23:47Not to mention you can easily hurt your fingers!
23:49A lot of modern sewing kits these days come with a designated place for safeguarding the needles.
23:55It's located at the bottom part of the thread spool.
23:58You'll just need to pull it out.
24:00It's even made to hold multiple sewing needles at a time.
24:04Disposable ballpoint pens come with a little secret of their own.
24:08Did you ever notice that in some of them, there's a small hole in the plastic part?
24:13It's actually a rudimentary ventilation system.
24:16It's supposed to let the ink easily make it to the tip of the pen.
24:20Okay, I know it's in the name, but you really don't need to shake the seasoning shaker to get any
24:26product out.
24:27Don't believe me?
24:28Hey, you're not the only one.
24:29Go grab your favorite seasoning bottle out of your pantry.
24:33If it has one of those removable plastic caps, it's perfect for the experiment.
24:38Instead of shaking the bottle, try holding it from the plastic cap while it's upside down.
24:44Now, gently twist the bottle from side to side and, before you know it, you get some gorgeously flowing seasoning
24:51without having to wiggle the shaker and make a mess all over the stove.
24:55On the same note, most salt and pepper shakers should have ridges on the bottom of the glass portion.
25:02In case you get any seasoning stuck in there, place the bottom of the salt shaker against the bottom of
25:07the pepper shaker and wiggle it around so the ridges click with each other.
25:11The seasoning should easily pour out now without you having to open the bottle.
25:16In colder weather, you often have so many clothing layers on you that you can hardly feel the purse or
25:23back straps on your shoulder anymore.
25:24Not to mention how fast they can slide off.
25:28Some jackets come with a built-in solution for that, in the form of a small tab on the shoulder
25:33with either a hook or a button.
25:35It's meant to be opened and closed comfortably, so you can keep your purse in place at any time.
25:42You're most likely using it merely to peel the skin of potatoes, carrots, or cucumbers.
25:47But you can use your vegetable peeler for chopping fine strips of onion as well.
25:52Just cut the onion into quarters vertically and then start slicing.
25:57This might also help out with those embarrassing onion tears.
26:01Most people miss this one, but should you ever have a closer look at your toothpaste tube, you will surely
26:07see some sort of coloring there, either a dot or a block.
26:12Colors can vary. They can be black, green, red, or even blue.
26:16These color spots are actually meant to help the assembly machines back at the toothpaste factory.
26:21They recognize when and where these machines need to cut the toothpaste tubes and proceed to fold them for packaging.
26:28For most types of footwear, if there's anything that seems a bit out of place, always know that it's there
26:34for a reason.
26:35Most manufacturers don't put extra items on shoes just for fun.
26:39It would definitely be a waste of time and resources.
26:42For footwear, like boots, for example, there's often a small loop at the top back of the shoe.
26:48It's there to help you when you need to put the shoe on since you can quickly pull on it.
26:53Plus, you can also hang the shoes somewhere, most likely to dry, since most boots are meant to be worn
26:59in the colder weather.
27:00Now, I've been guilty at least once of overdressing with a bunch of layers just so I won't need to
27:06jam everything in my check-in bag.
27:08But does it become a problem when you actually have to get seated?
27:12What do you do with your coat or your jacket?
27:15Well, have a closer look next time you board a plane on the seat in front of you.
27:20The hook that keeps the tray table upright can double as a jacket hook.
27:25As long as you don't need to have any meals while in the air, you're good to go.
27:29Now, most mascaras expire within three to six months, I'm told, depending on the manufacturer.
27:35But you can help speed up that process if you're not careful enough.
27:40Continuously pumping the mascara wand, trying to mix in the product, actually pushes more air into the tube.
27:46This can make it dry much faster, and you evidently won't get the desired results with it anymore.
27:52There's an easy way to check if your mascara is still good enough to use.
27:56If you don't hear a popping noise when you take the brush out, you may very well need to go
28:02get yourself a new mascara tube.
28:04Now, I know we're living in the era of Bluetooth-connected devices, but for better quality sound, they still recommend
28:12using headphones that connect via audio jacks.
28:15Remember seeing black ridges on those jacks?
28:18They aren't there just to make them fit when you plug them into your phone or laptop.
28:22Made out of a special insulating material, these bands are meant to guard the wires when sound is being transmitted.
28:30Based on the number of bands, you can figure out which end goes where.
28:34Some empty space under noodles in a cup doesn't mean the company producing them wants to cheat you out of
28:40a full portion.
28:40No, no. It's a manner of keeping the noodles intact during their transportation.
28:45It also helps with the circulation of hot water that is poured over the products before you can enjoy them.
28:52The V-shaped neckline was initially designed to serve a bunch of objectives.
28:56First, as a way of prolonging the life of the garment that would maintain its shape over the years.
29:01It's also there to fit your head through the shirt in case it needs some stretching.
29:06This way, it ensures a snugger grip around the neck.
29:10Lastly, it helps absorb sweat in case you're wearing the shirt while exercising.
29:15Now, it's not necessarily a custom anymore, but you may have stumbled upon a dinner jacket with an additional mysterious
29:22pocket on the right side.
29:24Turns out, this pocket was used by men to easily reach their train tickets since most of them had to
29:30travel to work every day.
29:31It helped them keep their jacket buttoned up, but also benefited from the use of a pocket.
29:37Now, it's only added as a decoration, and it doesn't serve an actual purpose anymore.
29:42Speaking of things we don't use these days, or at least for their initial purpose,
29:47did you know Play-Doh was originally a cleaning product?
29:51In the 1920s, the market was in need of a product that could help them wipe the wallpapered areas around
29:57coal-burning furnaces.
29:59The recipe for what we now know as Play-Doh was thus invented.
30:03It was manufactured in white only, and was supposed to clean wallpaper by being rolled back and forth over the
30:10dirt.
30:10It was only later, in the 1940s, that new products for cleaning wallpaper were brought up, and Play-Doh was
30:17redirected toward another area of the market.
30:20Now, while I enjoy a nice piece of toast for breakfast, isn't it pesky to have to clean out the
30:27toaster?
30:27Well, not anymore, since I recently found out that toasters have a slide or a panel at the bottom that
30:34helps get rid of all those annoying breadcrumbs easily.
30:40Now, there used to be a time when you could only have access to video games by inserting cartridges in
30:46your console of choice.
30:48These tiny objects gave many doctors a lot of headaches.
30:51People soon started popping up in hospitals after swallowing small game cartridges, especially the younger generation.
30:58Nintendo, the company that manufactures the majority of these devices, had to come up with a creative solution to prevent
31:06these accidents.
31:07So, these days, Nintendo Switch cartridges are purposely coated with specific chemicals that can leave a really bad bitter taste
31:15in the mouth.
31:16Not that I'd, you know, recommend you ever try and taste for yourself.
31:20Hmm.
31:21Seatbelt on the passenger seats has a fabric loop.
31:24When put under a great amount of pressure, the stitches on the loop rip apart, so the excess fabric can
31:30assist in cushioning the passengers.
31:32The extra few inches can make a great difference within a dire circumstance.
31:37However, there isn't one on the driver's side.
31:40As the driver is so close to the steering wheel, it's safer for them not to have one.
31:45Seatbelts were originally invented in the mid-19th century, though this technology wasn't brought into common practice until the 1960s.
31:54Pre-collision sensory technology has assisted with developing the safety of seatbelts and other features to the next level.
32:01Effectively predicting a car's collision, the technology directs the seatbelts to automatically tighten,
32:07aligning the airbags and ensuring the brakes will be preloaded to reduce shock.
32:12Every year, six million car accidents occur, which explains why all cars still must continue to develop safety features,
32:21not only to alleviate accidents, but to protect people more effectively within their cars.
32:27The materials that make up the body of cars only started getting replaced within the last 25 years,
32:33ranging from aluminum and magnesium alloys to carbon fiber composites.
32:38These lighter materials not only enable a more fuel-efficient journey, but they also ensure that when a car is
32:44in an accident,
32:45its build provides a crumple zone.
32:48As a car hits another object, the crumple zone absorbs energy from the collision.
32:53Although this would appear to cause more damage to the car, it helps prevent impact on the passengers.
32:58Front and rear bumpers are very underrated, and due to their long history of being used in cars,
33:05you can't imagine a time we didn't use them.
33:07They were invented in the late 1800s.
33:10The bumpers evolved over the years to the point we don't even realize we have them.
33:14But they're there, quietly waiting under the outer covers, consisting of compressible foam or plastic around a rigid reinforced bar.
33:24All the windows of your car are made of glass, but the windshield is made of a shatterproof version.
33:30It's laminated, so whatever might hit it, you can be sure there won't be any shards of glass falling into
33:36the front seats.
33:37Normal glass was used up until the 1950s.
33:41As vehicles became more prominent, they made modifications to ensure safety.
33:47Airbags seem like another common feature that has always been there.
33:50In fact, they were originally invented in 1968, and were ahead of their time.
33:56They slowly gained popularity, and through safety precautions for cars, they eventually became mandatory for all cars to have, only
34:04in 1998.
34:06They have since developed from just being an airbag within the steering wheel.
34:10Today, depending on the vehicle, they can be located throughout the car, ensuring all potential passengers will be protected.
34:17Crash sensors connected to an onboard computer detect when a collision occurs and trigger the bags, inflating within milliseconds and
34:26providing a cushioned safety within a blink of an eye.
34:29It can be difficult to predict the weather, and even more so to determine traction on the road.
34:35In the late 1960s, anti-lock braking systems, ABS, were implemented in vehicles.
34:41Before that, they had been used in many aircraft, with designs going as far back as 1908.
34:47They soon became a necessity for all vehicles, ensuring traction is maintained on slippery surfaces, and that there is complete
34:55control when braking.
34:56Today, ABS has advanced so much that the latest variations ensure further detection when there are strong crosswinds.
35:05Cruise control, initially invented in 1948, has been in constant development over many decades.
35:12Today, adaptive cruise control ensures that when the car is cruising at a constant speed and detects a slower car
35:19ahead, it will then adjust the speed to match the car in front.
35:22Other advanced variants may also ensure the car will make a complete stop, once identifying that the car in front
35:29has done the same.
35:31It's easy to forget to have your high beams on when driving on the long and lonesome road for many
35:36hours.
35:37Automatic high beams are quickly becoming more common.
35:40High-tech camera modules can easily determine what type of light is passing through and help ensure when the high
35:47beam will be necessary.
35:49Although versions of automatic high beams have been around since the 1950s, they counted on light-sensitive sensors and were
35:56very unreliable.
35:57The new varieties can identify the sources of light, whether it's from the sun, directly from a car's light, or
36:04even from the reflection on a sign, ensuring you won't cause issues with other drivers.
36:10It's a pain in the neck to have to ensure there isn't anyone creeping into that semi-visible corner, the
36:16blind spot, which causes around 400,000 accidents per year.
36:20Solar sensors within rear bumpers of vehicles and blind spot monitoring systems watch and identify adjacent lanes.
36:28They alert the driver that a vehicle may be in the lane beside them, whether by flashing lights on the
36:34dash or from beeping sounds.
36:36This way, they help to alleviate the many concerns the blind spot causes.
36:411.6 million road accidents are caused by texting and driving, and fatigue normally causes up to 10% of
36:49all car accidents per year.
36:50The driver attention monitor helps to alleviate both statistics.
36:54It works through sensors that monitor the car's movements and the amount of steering corrections to ensure the driver is
37:02paying attention to the road.
37:03When the system identifies that the driver isn't completely awake or is slightly distracted with their phone, it will prompt
37:10signals to suggest it's time for a break.
37:13Tires are among the most critical components for your car, with a close relationship with whatever path you take.
37:19Many safety features rely on the tires themselves for their own independent purposes.
37:24That's why it's super important to ensure the tires are always in top condition.
37:29Tire pressure monitoring systems check the air pressure of all four tires, ensuring you're aware when they need their pressure
37:36increased to avoid the risk of a blowout.
37:38The constant evolution in technologies continues to ensure you stay safe on longer stretches of the road.
37:45Lane departure warnings focus on the lines on the road, ensuring the car stays within.
37:51Whenever a car starts drifting over a line in the road without signaling to do so, the camera-based feature
37:56identifies and signals to the driver.
37:58The lane-keeping assist feature follows the same method of identifying when the car is intruding the bordering lane.
38:06When it gets too close, it will readjust the steering and center the car within its appropriate lane.
38:13Other features in more advanced cars have autonomous driving capabilities.
38:17The autopilot systems have taken cruise control to the next level.
38:21Not only does it allow the vehicle to steer itself in the intended lane while maintaining a set speed, but
38:27it also changes lanes when required, making the ride more and more efficient.
38:32Some safety features are only just making a trend in car models worldwide.
38:36For example, night vision using thermographic cameras to look out for pedestrians and animals nearby.
38:43It goes within the infotainment screen, facing frontwards and identifying objects from their heat signatures.
38:50It's estimated that there are over 1.4 billion cars in use worldwide.
38:55And as the world's population increases, it's expected that the number of cars will follow suit.
39:01Safety features will continue to adapt further beyond what we know of today.
39:06Infrared headlights will be further adapted to be used in conditions with poor visibility, like storms, snow and fog.
39:13They'll be capable of enhancing the visibility of the driver in all conditions without affecting the sight of passing drivers.
39:21Driver override systems will soon be able to monitor and identify human behavior.
39:26Whether due to reckless conduct on the road or for other safety precautions, cars will soon have the functionality to
39:33take complete control of themselves, ensuring both the passengers' and the driver's safety.
39:38Augmented reality windshields are in early development already, providing some indicator reflections from the dash onto the windshield.
39:46So, it's quite possible that soon all necessary directions from maps and alerts will appear right in front of the
39:52driver to ensure they never take their eyes off the road.
39:56Airbags will soon not only just be used within a car to ensure the passenger's safety.
40:01They will also activate from the outside of the car once they identify a definitive collision.
40:06The airbags will inflate outwards, covering the entire outside of the car and drastically reducing its impact.
40:13It may be so advanced that the bodywork of the car won't even need to be buffed out.
40:18The future technology of cars is expected to be so progressive that the cars themselves will have their own form
40:25of communication, not with human drivers, but with other cars.
40:29Just imagine, cars communicating and sharing information as they identify roadblocks, issues on the road, or disruptive weather patterns.
40:38It will all ensure the most efficient and safest route possible.
40:46So, take a small piece of fabric of a specific color and tie it to your luggage.
40:52This way, you'll save a lot of time waiting for your luggage to arrive, because most people have similar ones.
40:58But now, you can instantly recognize yours.
41:02It's annoying how often it feels like so many stick deodorants go to waste.
41:06You start feeling the container uncomfortably rubbing against your skin, even when plenty of deodorants are still left.
41:13But there is an easy trick to use the last bit in there.
41:17Unscrew the bottom and force a pencil underneath that moving platform to push another inch of deodorant out.
41:23That gives you a few more weeks to use it.
41:25Just don't poke yourself with a pencil.
41:27That's the pits.
41:30You're running out of your favorite hand cream, but it seems the tube still has some.
41:34If you cannot push hard enough to get the rest of it, take scissors, cut the tube of cream in
41:39half, and use one more day.
41:43When you wrote something on the paper and want to cross it out and not allow anyone to read it,
41:48don't just scribble over those words.
41:50Simply write random words and letters over the original, and no one will understand what the actual writing was about.
41:57I learned that one at spy school.
42:00If you often need something to prop up your phone, you don't have to look for random objects.
42:05Just take your sunglasses.
42:06They have the perfect shape of a phone holder.
42:10Use the inside of the toilet paper when you're at a public toilet.
42:14It's better to avoid covering the seat of a bathroom, too.
42:17When you flush a toilet, germs spring around and spray over the roll of nearby toilet paper, too.
42:22But if you have your own paper tissues, it'll be even better to use them.
42:28Greek yogurt flip cups
42:30You probably want something extra when eating your Greek yogurt.
42:33Like honey.
42:34You mostly get a tasty dollop of fruit and cookie crumbs.
42:38But those additional compartments are really narrow, so you can't even reach what's inside unless you have some tiny spoon.
42:45Well, check the word on the lid.
42:47It says flip.
42:48Yep.
42:49Flip those small compartments over so their contents can mix with your yogurt.
42:54Bon appetit!
42:56Business cards are so easy to lose.
42:59Next time someone gives you one, take a picture of it just in case.
43:02If you lose it somewhere in your bag, at least you know where you can always find it.
43:08If you're not sure how to iron a button-up shirt, just flip it inside out.
43:13That way you'll easily pass across the button side with your iron.
43:18Sometimes, even though you have a bag inside your trash bin, add the old newspaper to the bottom just in
43:24case.
43:24The paper will absorb food juices so they won't break through the bag and leave your bin messy.
43:31When you travel, make a bar of scented soap one of the essentials you take everywhere.
43:36Put it in the bag or compartment where you keep your dirty clothes.
43:40That will help to keep it smelling nice, at least until you find a place where you can wash it.
43:46There's a trick in how you can check if your batteries are good or bad.
43:50Just drop them on a table from around six inches.
43:53They're okay if they give just one tiny bounce and fall over.
43:56If not, if they continue bouncing around more, they're either on their way out or already dead.
44:06When you're taking a selfie and want to look more natural, squint your eyes.
44:10Not everybody feels comfortable in front of the camera, so you may look stiff.
44:14But this way, your smile will be more genuine in the photos.
44:19We all know how frustrating it is to have a container that doesn't fit in the sink and you still
44:24need to fill it with water.
44:26Just use a dustpan, a clean one of course.
44:29Place it in a sink and enjoy this brilliant new way in your bathroom.
44:34If you wrote down a recipe or had a cookbook and don't feel like going to your table and checking
44:40it out all the time, take a pants hanger.
44:42Hang it somewhere in your kitchen to continue with slicing, chopping and cooking and quickly check if you're following all
44:49the necessary steps.
44:51If you're not a fan of the taste of stale cereal, here's a trick that will help you keep them
44:56fresh even if they remain in the box for a longer time.
45:00Don't close the top panels of your cereal like you usually do with a square box.
45:04Pack it so it reminds you more of a milk carton.
45:07First, collapse three of the four pieces of cardboard to make an opening.
45:11Out of two long strips, leave one turned up.
45:14Now, tuck the two side panels inward into a V-shape.
45:18To hold it like this, pinch the unfolded flap of your cardboard into the opposite flap.
45:23Now, crimp the opening to keep it in place.
45:26With a tighter seal, your cereal will remain fresh for a longer time.
45:31Place a wooden spoon across a boiling pot of liquid.
45:34That way, you'll prevent it from boiling over.
45:38We all sometimes lend our stuff to friends and forget who took what.
45:43Take a picture of them holding the item so you remember where your things are.
45:48Chargers can sometimes bend if you carry them around in a bag.
45:52Take a spring from one of your old pens and wrap it around the critical part of the cable.
45:57It will prevent the cable from breaking.
46:00Now, we all love pancakes, sure.
46:02But preparing them can be really frustrating because it's almost impossible not to make a mess.
46:08Hmm, almost.
46:09If you use an old ketchup bottle and fill it with pancake mix, you'll certainly avoid most of the cleaning
46:15after it.
46:16And have a nice treat, too.
46:19If you like going to the beach but are often afraid someone might take your stuff, try this trick.
46:25Take an old bottle of sun lotion and clean it out.
46:28Place your phone, keys, and money inside and close it.
46:32Looks casual enough for people around to think you don't have any valuables within your stuff.
46:38If you're having a barbecue gathering with your friends and looking for a practical way to serve condiments, here's a
46:44simple solution.
46:45A muffin tin.
46:46Less mess because you'll cut down on dishwashing.
46:49Plus, you save space at the table and keep things more organized.
46:54How to finally be able to differentiate your keys that all look so similar?
46:58Take different nail polishes.
47:00Now, you'll only need to remember which color is for which door.
47:04We all sometimes forget to put deodorant on before leaving the house.
47:08No worries.
47:09Just pat your armpits dry and go with hand sanitizer.
47:13It's an excellent way to deal with bacteria that are actually a true reason for that unpleasant smell when sweating.
47:19Now, if you're keeping count, that's the second tip today about your armpits.
47:23Just saying.
47:24When you want to amplify the sound and don't own speakers or any other equipment that would help you,
47:30just place your phone in a glass jug.
47:32Woohoo!
47:33Party!
47:35Save a couple of toilet paper rolls and use them as cuffs, so your wrapping paper doesn't unroll and make
47:41a mess.
47:43Any fans of iced cappuccinos or iced coffee here?
47:47Prepare some coffee and make frozen coffee cubes.
47:50That way, your beverage won't get watered down when you want to make it colder.
47:54When mobile phones just turned up, it looked like designers wanted to make them as small as possible.
48:00But over time, phones got so many other options besides just texting and calling.
48:05So, many new models, for example, the latest iPhones, have a bigger screen now.
48:10It seems like now you need to use both hands for typing once again.
48:14Unless you change the keyboard setting.
48:16Open the keyboard, any app is good, and look for the global icon or the emoji icon.
48:22Press it and hold it down until you see the keyboard menu pop up.
48:26Do you see those three keyboard icons at the bottom?
48:29Pick the left one if you're right-handed, so the keyboard on your phone will compress itself to the left
48:35side.
48:35The keyboard will move toward the right side if you take the right side.
48:39Or, go to Settings, then General, choose Keyboard, and then One-Handed Keyboard.
48:45You get the same result.
48:49You must have noticed those lines on some kinds of chips.
48:53For one thing, they help with the distribution of spices and seasonings.
48:57In other words, all those substances that make your chips taste like cheese are mostly stored inside the lines.
49:05Plus, the lines make chips crunchier.
49:09Some cars have a tiny coffee cup sign on their dashboard.
49:13It's the vehicle's anti-drowsiness mechanism.
49:17There are manufacturers that equip their cars with a drowsiness detection system.
49:22It analyzes the speed, wheel angle, and lane deviations to figure out if it's time for the driver to take
49:29a break.
49:30If it is, the vehicle makes several audio signals and the coffee cup sign starts to flash.
49:38Some plastic milk containers have dents on their sides.
49:42These dents serve several purposes.
49:45For one thing, when milk spoils, this process usually causes swelling and high-pressure buildup inside the container.
49:52That's when the dent comes in handy.
49:55It pops out and doesn't let the jug blow up.
49:59Plus, if you decide to freeze the milk, it will expand like any other liquid.
50:04And then again, the indentation will pop out and prevent the container from breaking inside your freezer.
50:12You might have wondered why jerry cans have three handles.
50:16It's a clever designer move.
50:18This way, if you carry the container alone, you can use only the central handle to distribute the weight evenly.
50:26But if your friend wants to help you out, each of you can grab the side handle.
50:32The first jeans had a problem.
50:35Workers and miners, who were the original jeans wearers, put too much pressure on the poor piece of clothing.
50:41As a result, the seams couldn't withstand the stress and tore.
50:47Tiny metal studs were invented to prevent this from happening.
50:52Sticky notes come off relatively easily because their adhesive is spread out across the paper unevenly, in small blobs.
51:00And only some of these blobs touch the surface of whatever you've stuck the note on.
51:05That's why when you unstick a post-it and attach it to something else,
51:09it still works, until all the glue gets used or covered with dirt.
51:15Soda bottles are always filled in such a way that there's some space between the liquid and the cap.
51:22That's because soda contains carbon dioxide.
51:25It's a gas that can expand once a bottle is heated.
51:29If there's no gap in the bottle, it can break because of the pressure building inside.
51:35Also, when you open your drink, the gases go out in the form of bubbles, and the drink is likely
51:41to overflow.
51:42The gap helps with this problem, too.
51:46Dental floss is super useful for your teeth, but it might be rather hard to operate.
51:51It regularly slips out of your fingers and tangles.
51:55To avoid these problems, tear off a piece of dental floss and tie its two ends together.
52:02It'll be much easier to use and won't hurt your fingers.
52:06Now, about those horizontal lines on plastic bottles.
52:11They help hold bottles up.
52:13Some bottles are produced from soft plastic.
52:17Without the lines, they wouldn't keep their shape.
52:20Instead, they would twist easily or even break.
52:25The soft, round part under a soda bottle cap keeps the carbonation from escaping.
52:31Without it, your pop would go flat in no time, probably even before you buy it.
52:38If you don't have anywhere to put a toothpick after using it, break off its flat end at the first
52:44groove and place it on the table.
52:46Now, you can balance the used portion of your toothpick on the grooved part so that it doesn't have to
52:52touch the table.
52:54You can also make a makeshift stand for disposable chopsticks.
52:59They have a sort of lump on one side.
53:01Break that lump off before you split the pair.
53:05Now, when you want to take a sushi break, just place the stick on this stand.
53:12Donuts are shaped like rings because, otherwise, they might get overdone at the edges but uncooked and gooey inside.
53:21With a hole in the center, both the outside and the inside get ready at the same time.
53:28Ever notice that layer of clear fluid in gel pens?
53:32It's called the ink follower or stopper fluid.
53:36The gel in such pens contains pigment particles dissolved in a polymer solution.
53:42The gel should be thick enough to keep the pigment particles suspended, but also thin enough to flow first onto
53:48the ball and then the paper.
53:52The main task of the stopper fluid is to be a barrier to prevent the gel from evaporating or leaking
53:58out.
53:59Without this transparent fluid, your gel pen wouldn't function.
54:03The fluid always stays in one position and doesn't get dissolved with the gel.
54:08Neither does it move backward or flow out of the pen.
54:13Some button-down shirts have a button hidden on the back of the collar.
54:18Its main purpose is to prevent the tie from sticking out from under the collar.
54:23As for that locker loop on the back,
54:27you can use it to hang the shirt on a hook to avoid wrinkling it.
54:33Outer rings and zipper sliders, especially when two sliders are used together,
54:37are added so that you can connect them with a lock and keep sticky fingers away.
54:44Most ambulance cars have this word printed on the front of the vehicle.
54:48That's the word ambulance backward.
54:52It's written in reverse so that the driver in front of the ambulance can see the word properly in their
54:57rear-view mirror.
54:59Then they can move out of the way and let the ambulance pass.
55:05Escalator brushes serve an important safety purpose.
55:08You might have heard that most accidents happen after people get their bags or clothes stuck in escalators,
55:14because they stand too close to the sides.
55:17But when there are nylon brushes on both sides,
55:20you can't but keep your feet away from the escalator's skirt panels.
55:24The result? No accidents.
55:27The side holes in sneakers are for laces.
55:32Since sneakers were originally invented for basketball players,
55:35this interesting design allowed them to accommodate any player's foot.
55:40They just needed to lace their sneakers in the most comfortable way for them.
55:45The holes in the bottoms of your earphones allow air to circulate up and through the speakers.
55:52It helps to increase low frequencies, making the bass sound deeper.
55:57The quality of the sound also becomes much better.
56:01Ever been stranded with a cup of applesauce, but no spoon at hand?
56:06But each snack pack already has a built-in spoon.
56:10Several twists of the foil lid, and here you go!
56:16Diamond slits on backpacks were originally placed only on traveler bags.
56:21Their purpose was to carry robes.
56:24These days, you can find such slits on almost every backpack.
56:28Why not use them to carry a bottle of water, an umbrella, or a pair of sneakers?
56:35Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
56:42Yellow and light green hues are the most popular,
56:45because they don't prevent you from seeing the text after black and white photocopying.
56:51Photocopiers perceive yellow and light green marks as almost non-existent and don't print them.
56:58A stop sign has an octagonal shape to help drivers recognize it easily, even if they see it from the
57:05back.
57:05When the signs weren't reflective yet, this shape prevented drivers from confusing the stop sign with any other night.
57:14The number 57 on a Heinz ketchup bottle has nothing to do with the product label.
57:20The truth is that the place with the numbers is the very sweet spot you should tap to get the
57:26ketchup flowing.
57:28So, stop hitting the bottom of your sauce bottle and hit 57.
57:33Lots of private houses have triangular-shaped roofs, because this allows rain, snow, and fallen leaves to slide off the
57:41slope.
57:42If all this stuff piled up on top of your house, one day, your roof would collapse.
57:50Airplane windows have rounded edges, and that's a crucial safety measure.
57:54It prevents aircraft accidents.
57:57Weak spots are usually situated in the corners.
58:01If airplane windows were square or rectangular, each of them would have four potential weak spots.
58:07Under pressure, they would collapse.
58:09You could just raise two.
58:10Goose.
