00:00Now, don't blame that little lump on your computer cable for getting stuck somewhere for the umpteenth time.
00:07The cylinder, shapes and colors may vary, actually prevents interference from other signals, like those your phone emits.
00:15A lack of privacy in public bathrooms, I mean those large gaps beneath where normal doors tend to be, is
00:22there for a reason.
00:23This way, people do their business faster and there are fewer lines.
00:28Also, if something goes wrong, it's easy to find a person who needs help.
00:33In London, there are some poles that kind of look like street lamps, but there are no bulbs.
00:39Well, their official name is stink pipes, and they're a thing of the past now, but they used to come
00:45in handy back in the nineteenth century.
00:47These hollow poles would vent away the air and explosive gases with bad smells to prevent, shall we say, unwanted
00:55consequences.
00:57Blank pages in the books aren't actually for the author's signature.
01:01It's all about the manufacturing process.
01:04Books are printed on large sheets, so one sheet can fit in four pages.
01:09If a book has an odd quantity of printed pages, chances are you'll get a blank one for notes.
01:15Now, originally, golf balls were smooth, but some time ago, players noticed that overused balls with damages flew better than
01:24brand new ones.
01:25At some point, they started producing balls with dimples.
01:30Windshield black dots help disperse the sun glaring right into your eyes.
01:34This sort of frame keeps the UV rays away, so it serves as sunglasses for your car.
01:41The tab on the rearview mirror has obvious functions.
01:44It holds your air freshener, that cute toy.
01:47But in reality, it was meant to be a tumbler between day and night mode.
01:52It reduces the glare from the car behind you, so you can't be blinded.
01:58Colored dots on chip bags aren't as useful as those on the windshield, but they have a purpose too.
02:04Manufacturers need them to control the package color and show what ink color was used on the package.
02:10Eh, no big deal.
02:11Your microwave has a silent mode.
02:13Seriously.
02:15If those beeps drive you nuts, press 1 or 0 and hold.
02:19It might work.
02:21Also, there is sometimes a silent button you kept ignoring all this time.
02:25Anyway, there are no two identical microwaves, so a manual should come in handy.
02:32Grocery cart loops have more functions than you think.
02:35You don't want to put your fancy white jacket in a cart next to carrots and coke.
02:40This little hook-like thingy helps organize all the stuff in your cart better, so you can enjoy your shopping
02:47trip.
02:48Another thingy we often neglect is a point on an ointment cap.
02:53Most tubes are usually sealed with plastic film or foil, and opening it with your fingernails isn't the best idea.
03:00A point easily opens even the most safely sealed tube.
03:06Automatic lip liners and eye pencils have a sharpener installed in the package.
03:11The lid on the back part of the pencil doesn't only reveal the color.
03:15You can pull it out and sharpen up the product.
03:18Toothpicks come in different varieties, and one of them is a bit puzzling.
03:23Sometimes they have several grooves.
03:25The first one is weak, so it's easy to break the toothpick in two.
03:29The smaller section with one more groove can be used as a stand to avoid the contact with the table.
03:37You can make a makeshift stand for disposable chopsticks.
03:40They have a sort of lump at one side before you split the pair.
03:44So, next time you have a sushi dinner, try breaking off that lump instead of regular splitting.
03:51When you want to take a sushi break, just place the stick on this stand.
03:56Yeah, you've heard before that a drawer beneath your oven is there for keeping the food warm if the guests
04:02are running late.
04:03Here's one more hidden function.
04:05You can slow cook on lower temperatures in that drawer, too.
04:09All the bottles used to be of the same green color once.
04:13But later it was discovered that brown ones are way better at blocking UV light.
04:19Say no more.
04:21Stickers on fruit seem to provide zero information about the product.
04:25But if you look closer, you'll find some numbers that can tell you more.
04:30A five-digit number where the first number is nine is a good sign.
04:34You're about to buy an organic product.
04:37A four-digit number starting with a three or four means it was conventionally farmed.
04:43And if the number starts with an eight and there are five digits, well, it's best to leave it on
04:48the shelf.
04:50A dollar has its secrets, too.
04:52A large letter with a rim shows which bank is responsible for issuing this bill.
04:58There are 12 banks distributing currency.
05:01For example, the L says it was printed in San Francisco.
05:06Now, some cups look like they're chipped on the bottom, but they're produced this way.
05:11In fact, these dimples are supposed to keep the cup in place on wet surfaces, and it doesn't let excess
05:17water accumulate while it's in a dishwasher.
05:20Small hollows in a chocolate box are designed for chocolate lovers.
05:24Press the closest deepening to the chocolate that you want to grab, and it'll jump out of the box right
05:30into your hand.
05:32Bath foam can be more than just a pleasant smell.
05:35It also has a sort of thermoregulatory function.
05:39The bubbles save water heat, so you can enjoy your bath a little longer.
05:44Disclaimer, it works for acrylic bathtubs only.
05:47Those made of metal lose heat fast, no matter how much foam you make.
05:53A good doorknob is one that's made of brass, bronze, or some copper alloys.
05:58These metals have an anti-germ effect.
06:01Bacteria spread way slower on them.
06:04They also get rid of germs pretty fast, within a couple of hours.
06:08No, it doesn't mean you don't have to wash your hands.
06:12If you pour milk or juice right onto your t-shirt every single time, you're probably not doing it right.
06:19Try pouring it from the other side of the carton.
06:22It sloshes less and is easier to control.
06:26There's only one way you can store your peanut butter right.
06:30If you place it the regular way, it may get a bit solid before long.
06:34The trick is to store it upside down, so the oils don't stay on the bottom all the time and
06:40distribute evenly.
06:42A dinner jacket has small pockets above regular ones, and they're not useless.
06:48They're called ticket pockets, and were designed so that gentlemen wearing such jackets could easily access the tickets and show
06:56them on a train.
06:57They could also store cash and other small loose items in a super convenient way.
07:02Now, whatever coffee shop you go to, all the disposable cups look exactly the same, only the logo changes.
07:10The secret here is the special shape that allows you to enjoy your drink easily.
07:16The top is always wider, which allows it to accommodate your nose while you're drinking.
07:21And the bottom is always narrower, so that anyone can hold it easier, even if the hand is quite small.
07:28This width difference also allows the cups to stack.
07:33Triangular flaps on small juice cartons can help control unwanted spillage.
07:38If you flip them and use them as handles for the carton, you won't press the package so the juice
07:43won't be squeezed uncontrollably.
07:46Now, if you have a mason jar and a blender with a screw on top, this secret is life-changing.
07:52You can actually put a mason jar directly onto the blender and make any shake you want without having to
07:59wash the blender jar.
08:00Just don't put your device on max.
08:04There's one trick you can use to make salt and pepper come out smoothly.
08:08Grab a container with pepper or salt.
08:11Turn it upside down.
08:12There are ridges on the bottom of the shaker.
08:15Now, grab the second container and rub those ridges together.
08:18The vibrations will make the product literally flow out.
08:23Most headphones, both wired and wireless, have little holes.
08:27They're needed to ensure good sound.
08:30The air circulates through those holes, which is important for the sound quality.
08:35Stick sachets were designed smartly.
08:38No need to tear one of its edges.
08:41The right way is to tear them down the middle.
08:43Now, you may say it's not a big difference,
08:45but at least there's less mess with those torn paper bits.
08:50If two zips for one section seem a bit too much for you,
08:54it's probably time you started using them wisely.
08:57It's a great pickpocket proof.
08:59You can put on a small lock on those zippers
09:02and make sure no one but you can open your backpack.
09:05Hide the key in the fifth pocket on your jeans
09:08that was originally designed to keep watches safe.
09:11So, now you know.
09:15So, you hungry, but not quite ready to eat a three-course meal just yet?
09:20How about some instant noodles instead?
09:22Ah, the water's boiled, your tummy's rumbling, but there's a problem.
09:27The styrofoam cup's broken and the noodles are exposed.
09:30Wait, is that a space at the bottom of the cup?
09:33Why?
09:34That space is for protecting the noodles.
09:37It's not the company trying to save money or anything.
09:39Notice how the ramen in cups is hardly ever broken,
09:43but the one in the packet comes out looking like a mess?
09:46This technique is called a middle suspension.
09:49The noodles are packed in tightly to stop them from getting crushed in the delivery truck.
09:53It's not just about the noodles looking nice and long.
09:56It also helps those tasty noodles soften more easily.
10:01Now, morning breath isn't the best.
10:03Luckily, there's an easy way to get rid of it.
10:05Yeah, it would have been easy to think that mouthwash was invented for, you know,
10:10washing your mouth.
10:11Well, mouthwash was originally invented and sold as a floor cleaner.
10:16It was sold to hospitals as an antiseptic for years.
10:19It never really took off.
10:21Some genius in marketing rebranded it as a mouthwash.
10:25And the rest is minty fresh history.
10:28So, after you've cleaned your teeth, just remember, rebranding can be pretty powerful.
10:34It's hard to imagine a world without the internet these days.
10:37No streaming, no online games, or pictures of cute little kitties.
10:42Yeah, that's not what it was designed for.
10:44But who cares, right?
10:45The prototype internet was called ARPANET, or the Advanced Research Projects Agency Network.
10:52This machine was very sensitive.
10:54To stop anyone from turning it off, some clever scientist stuck a piece of paper on it with these powerful
11:00words.
11:01This machine is a server.
11:02Do not power it down.
11:04It was written in red ink.
11:06Hey, nice touch.
11:08Having your professor scribbling in the margins of your notebook isn't exactly new.
11:13Except that margins weren't designed for that.
11:15They're rat protection.
11:17Back in the day, rats would nibble on paper all the time.
11:21So, if you wrote something on the edge of the paper, it ended up inside a hungry rat.
11:26A couple of well-placed lines stopped your best answers from getting eaten.
11:31Hey, I can't finish this pizza.
11:34Time to cover up those leftovers.
11:35Luckily, I have plenty of plastic wrap.
11:39A little tug, and the roll just jumped out.
11:42Prison break!
11:43If you look at the wrap's home, the long, thin box, there's a special little feature that can help you.
11:49A cardboard tab on each end.
11:51Push them in, and the roll's not going anywhere.
11:55Strange that I've never seen them before.
11:58It's lunchtime.
12:00I'm feeling like a California roll today.
12:02Seaweed, rice, cucumber, avocado, and crab meat.
12:06Or is it?
12:08It's actually imitation crab meat.
12:10It's basically cheap white fish blended with sugar.
12:14The fish mixture is then heated and pressed into shape.
12:17Mmm, yummy!
12:19That's maybe why it's called the hot dog of the sea.
12:22Nah, I just made that up.
12:24Your microwave has a secret we've all seen, but never paid attention to.
12:29That black mesh you see on the door is a Faraday cage.
12:34It stops the electromagnetic energy, or the microwaves, from escaping.
12:38And cooking you, too.
12:40That's how it heats up your food so quickly.
12:43Every microwave has to have one, and they all vary in quality.
12:47This Faraday cage can even stop signals from your phone.
12:50Which I guess is useful.
12:51Hey, you don't need your popcorn to stop popping in order to take a call, do you?
12:56Airplane mode's a bit easier, though.
12:59Ever taken an IQ test and realized you're Einstein-level smart?
13:04Me neither.
13:05The median IQ is only 100.
13:08Plus, there's very little evidence that Einstein ever even took the test.
13:13In the beginning, most people thought the tests were too vague to be helpful in any way.
13:17The test was designed for children who needed help with their studies.
13:21Later, they realized it could be adapted to identify intelligence.
13:25But it was never originally designed for that.
13:29Hey, never pop bubble wrap.
13:31You're missing out.
13:32And you guessed it.
13:33It was never meant to be popped or used in the way we use it today.
13:37It was invented as a new, textured wallpaper.
13:41By sealing two shower curtains together, they created the first bubbles.
13:45The idea never really took off, obviously.
13:49After failing as wallpaper, it discovered its true meaning in life.
13:53It could protect sensitive items.
13:55When the first computers were being shipped, bubble wrap was there to help.
13:59Imagine a house with bubble wrap wallpaper in every room.
14:03Best or worst thing ever?
14:05Hey, leave me a comment below.
14:07If you owned one of the biggest companies in the world, selling one of the most known products on the
14:12planet, how would you keep your company's secret a secret?
14:16The formula for Coca-Cola isn't patented.
14:20The first recipe was, but when they made changes, no patent ever went through.
14:25The secret formula is still only known by a few people at the company.
14:30Not only that, but not even Coca-Cola's rival wants the recipe.
14:34In 2006, a disgruntled employee tried to sell off the secret, but it didn't work.
14:42Hey, take a look at your brand new mattress.
14:44Do you see the Do Not Remove Under Penalty of Law tag?
14:48Wow, that thing looks pretty serious.
14:50Good news, though.
14:51The tags aren't meant for you.
14:53They're aimed at the mattress seller.
14:55A hundred years ago, mattress makers used to create the filling with basically anything.
15:01Animal hair, old hospital beds, or clothing.
15:04Then, strict laws stopped old hospital beds from being used.
15:08Their mattresses were filled with germs.
15:11Now, on a rainy day, Play-Doh is something everyone can make at home.
15:16Mash up some flour, water, salt, food coloring, and wham!
15:20Any creative person is amused for hours.
15:23Cheap, clean, non-toxic, the perfect modeling clay.
15:27But it was never made for that.
15:30This stuff was originally for cleaning up walls in the 1930s.
15:34That's because people started going crazy for wallpaper, which you couldn't use soap and water on.
15:39Eventually, Play-Doh had to find a new home.
15:43Now, have you ever finished a lollipop and noticed a hole in the stick?
15:47This hole isn't just for show or to make a musical instrument with after you're done.
15:52It's there to keep that tasty sweet treat from falling off.
15:56While the candy's still hot, it's poured into a mold.
15:59As it hardens, the candy flows into the hole and creates an anchor.
16:04Oh, not into lollipops?
16:06How about good old American gummy bears?
16:09Unfortunately, they aren't American at all.
16:12They're German.
16:13A German company started making them in 1922.
16:17The original name was Gummy something-something.
16:20Anyway, they got the inspiration from real dancing bears at live shows.
16:25These treats eventually made it all the way around the world.
16:29Hey, ever wondered what those little bumps were for on the F and J keys on your keyboard?
16:35These little raised ridges are to help your index fingers be in the best possible spot for lightning-fast typing.
16:42Keeping those fingers on F and J, it makes it way easier to reach all the keys, especially if you
16:48don't look at the keyboard.
16:49Now, everybody loves a Slinky.
16:52If you've ever watched one of them strut down the stairs with groovy music in the background, congrats!
16:57You're definitely a YouTube fan.
17:00People of all ages loved it when it came out.
17:03Which is crazy because it was never meant to be a toy at all.
17:07It's a spring.
17:08It was originally designed to stabilize sensitive nautical devices on ships.
17:13Nothing fun about that at all.
17:15Until that amazing day when one of them fell off a table and danced its way into our hearts.
17:22After many experiments, the new and improved Slinky was born.
17:26Give that team of scientists a medal.
17:29Now, that little pocket on your jeans wasn't designed for loose chains or keys.
17:34It was originally made to store your pocket watch.
17:37You don't have a pocket watch?
17:38How is that possible?
17:40They were all the rage in the 1890s.
17:43But that's not all that makes your old pair of jeans interesting.
17:47Look around the pocket areas.
17:49You'll see rivets sticking out.
17:51No, they're not some cool fashion idea from the past.
17:54These rivets serve a very crucial role.
17:57They help protect the sensitive areas of the jeans that get the most wear and tear.
18:02Back in the day, most people wore jeans to do hard manual labor.
18:06So, they needed to be tough.
18:07If those guys back then saw you paying a hundred bucks for a pair of ripped jeans, they'd probably pass
18:14out from shop.
18:16So, grab your phone.
18:18Good.
18:18Now, turn it around.
18:20You see that little dot between the camera and the flash?
18:23That's a tiny microphone.
18:25Bet that's something you didn't know.
18:27What's it doing there?
18:28Well, when you're on a phone call, this little guy is busy at work, reducing the amount of background noise
18:34other people hear when you talk.
18:36That's right, if it wasn't for this, calls wouldn't be as nearly as crisp as they are now.
18:43You're lost in the woods, and you're rushing to get back to camp.
18:47You suddenly remember you've got something that can help.
18:50You grab one of your chest straps from your backpack and whistle on it.
18:55Yup, that's right.
18:57A lot of bags have this feature in them, especially the ones made for the outdoors.
19:01It isn't long before you hear the call of one of your friends, and you follow them back to the
19:06warm campfire, saved by this cool bit of design.
19:11If you're a curious person, you might have wondered what that little pocket in your jeans is doing there.
19:17You know, the one that's inside the bigger pocket.
19:20People often use it to store coins and bills, but it's not meant for that.
19:25It's actually designed to store your pocket watch safely.
19:28Ah, maybe that's where the name pocket watch comes from.
19:34You finally arrive home after a long day's work.
19:37You understandably don't feel like cooking, so you sit on the couch and watch a bit of TV and order
19:43some takeout.
19:44How about Chinese?
19:46Ah, perfect.
19:47There's the doorbell.
19:49That has to be your food!
19:50It smells delicious!
19:52Wait, before you grab the plates, do this instead.
19:55Open your Chinese food container on the table.
19:58It becomes the perfect plate.
20:01And it's cardboard.
20:02Which means no cleaning either.
20:05That can of soda you got with your food has a cool feature too.
20:09Look at the tiny metal tab there, the one you used to open the can.
20:14Guess what?
20:14You can fit your straw in there.
20:16In fact, that's exactly what they're made for.
20:19Go ahead, try it for yourself.
20:22If you're not at your computer, take a look at your keyboard right now.
20:26If you're not, that's okay.
20:28Here's one on the screen.
20:29The keycaps are arranged in what's called the QWERTY layout, named after the first six keycaps below the numbers.
20:37As it turns out, it wasn't always this way.
20:39They used to be laid out alphabetically, which would make more sense when you think about it.
20:44The alphabetical layout fell out of use because long ago, there were things called typewriters.
20:50Remember those?
20:52You press down a key, and a typebar would fly out, hitting an inked ribbon and stamping a letter on
20:59the piece of paper.
21:00Eventually, typists got good at this and typed faster.
21:04Too fast.
21:04The typebars would eventually get caught in a log jam with each other, ruining the flow.
21:10To fix this problem, they made keyboards with randomized keycaps.
21:14The new layout actually worked better because it made typing harder, helping to slow typists down and prevent the typebars
21:21from getting stuck.
21:22Much better!
21:23Today, no typebars.
21:25No typewriters, mostly.
21:27People are still fast nowadays, but you just can't help but wonder who was faster, though.
21:32Us or them?
21:34Keyboards have another hidden feature, too.
21:37Have you ever noticed that the F keycap and the J keycap have little bumps on the bottom of them?
21:42As it turns out, they're there to help people figure out where they are on the keyboard without having to
21:47take their eyes off the screen.
21:51Grabbing a takeaway cup of coffee at your favorite cafe might be just what you need to fully wake up
21:56in the mornings.
21:57When you get back home or to work, though, you might be afraid to stain your desk when you put
22:02the steaming hot coffee down.
22:04Worry not!
22:06Your plastic lid isn't only good for keeping your coffee hot.
22:09It also doubles as a coaster.
22:11In fact, they're the perfect size to hold a cup.
22:14Try it for yourself.
22:17This one's going to come in handy if you're a home cook.
22:20If you're like me, you might have a bit of trouble deciding how much pasta you need for just one
22:25serving.
22:26Well, if you've got a pasta scoop, grab that.
22:29Most people don't know what the little hole in the middle is for and assume it's supposed to help with
22:34water drainage or something.
22:36It turns out that it helps you measure out a perfect serving.
22:40Just see how much dry spaghetti you can fit in the hole and use that as one portion.
22:47Out of the store buying coat hangers, you might notice that the plastic ones feel cheaper than the wooden ones.
22:53There's a good reason for this.
22:55Wooden hangers are made out of cedar wood.
22:58The big difference between the two is that the wooden ones repel bugs and moths.
23:04They're stronger and last longer too, perfect for things that might stay in your closet for a long time.
23:11When you brush your teeth, you might have noticed that your toothbrush has blue bristles.
23:16They're not just there for show.
23:17In fact, they're there to tell you when it might be time to switch toothbrushes.
23:22These bristles lose their strength and color when the brush has been worn down,
23:27letting you know that it's time to get rid of it.
23:31Microwaves often look a bit like mini-TVs,
23:34especially ones where you can clearly see the black film around them.
23:38This is actually a really important feature that's used to keep the radiation from slipping away.
23:44They're called Faraday cages, if you want to get technical.
23:47This is why you can stand next to a microwave without melting into a puddle.
23:53That's not to say you should stand in front of the microwave and watch your food heat up,
23:57but at least you know you won't grow an extra ear or something.
24:01Okay, not really.
24:03Some ovens have a drawer under them.
24:05It's tempting to use this to store random junk you don't use often, but there's a better use for it.
24:11Instead, this should be used to help keep the food that's waiting to be served hot.
24:15You can take it out of the oven and store it right in this drawer,
24:19keeping your oven free for you to carry on cooking.
24:23Now, you're on a plane looking around, trying to pass the time before takeoff.
24:28When you examine the window, you notice this has a little, very tiny hole on its bottom.
24:33Don't worry, it's not broken.
24:36It's there to relieve the pressure that builds up over time as the plane goes up and down.
24:41It also lets the air flow through it.
24:44Now, raise your hand if you've ever ridden on an escalator and scrubbed your shoes on its bristles.
24:49Hey, I'm guilty of doing that, maybe more than I should.
24:52It's not there to clean your shoes, though.
24:54It's an important safety measure.
24:56It stops your shoelaces, clothing, and other stuff from getting stuck in there,
25:00avoiding a nasty scene when you go to get off.
25:05Sometimes a piece of fabric comes with your new clothing.
25:08It usually comes along with the extra buttons in a little plastic bag.
25:12You might think it's just a piece of fabric to use for future patching, in case you rip it.
25:17But that isn't its purpose at all.
25:20It's actually supposed to be put in the washing machine to test how it reacts to various washings.
25:25Now, you don't have to worry about shrinking your new expensive coat
25:29because you know how it'll react to the wash.
25:33Bubbles!
25:33Who doesn't love bubbles?
25:35Most people have fond memories with bubble blowers as a kid.
25:38But as adults, the closest thing we can get to recapturing that feeling is with bubble baths.
25:44After a hard day at work, there's nothing better than dipping into a nice warm bubble bath.
25:49Right, guys?
25:50And the bubbles do more than just clean you.
25:53If they're high-quality bubbles, they'll serve as a heat insulator.
25:57So they make sure that your bath stays warm for longer.
26:02Boxes of chocolate sometimes have these mysterious holes in them.
26:05When I'm eating a box, or two, I usually ignore them and take out the chocolate by pressing the bottom
26:12of the plastic.
26:13But it turns out that I've been doing it wrong the whole time.
26:17If you press one of the holes, the chocolate comes right out.
26:21I'm certainly going to start doing this from now on.
26:25Here's another one from the kitchen.
26:27The handle on a pot will often have a hole in it.
26:31Most people use this to hang them on a nail on the wall as an easy storage method.
26:36The hole has another use, too.
26:38When you're cooking, you can use this handle to hold your wooden spoon or whatever else you might be cooking
26:44with.
26:44This makes sure you don't make a mess when you put it down.
26:49Glass bottles usually come with a cap in them.
26:52Well, duh!
26:53Otherwise, the liquid would just spill.
26:55In this cap, there's a plastic liner that seemingly has no purpose, right?
27:00Wrong.
27:01It's a seal!
27:04No, not a seal!
27:05A seal!
27:06It's the kind that helps keep your drink fizzy.
27:09Ah, just the refreshment I needed.
27:12A lot of doorknobs are made out of brass, and it's not by chance.
27:16They're made out of this specific material because it's bacteria's worst enemy.
27:21That's right, it destroys them.
27:23Perfect for those who want to keep a clean house and avoid germs.
27:27Hey, you want a fish?
27:32Many shirts have two buttons on the cuffs, but only one buttonhole.
27:36So what is the second button for?
27:40Turns out you can use it whenever you're wearing a watch, so the cuff is looser.
27:45Most clothing items you buy come with a small bag of fabric or a button, or both.
27:51Buttons obviously can be used as a replacement if you lose the original ones.
27:56Pieces of fabric can be used to patch up a hole, but most importantly, it's a tester.
28:01You can use it to test different washing products on it and see what happens to the fabric.
28:08Some umbrellas have a tip at the top, and it turns out it's not just a pretty design.
28:13When going inside on a rainy day, you should just close your umbrella and tap the tip against the floor
28:20to drain the water faster and more effectively.
28:24Many backpacks have this diamond with two parallel cutout slits on its front, and it's there for your comfort.
28:31You can attach something to it, like a water bottle or shoes.
28:35It comes especially handy if you travel somewhere or go hiking, so you don't have to hold your stuff.
28:43Okay, the next thing is gear loops, and probably from the name of it, you already have an idea what
28:49they're there for.
28:50You can strap in some useful gear you need to have with you, like trekking poles or shovels.
28:55Some gear will need to be secured to do it.
28:58Drop the handle through the loop and rotate it upward.
29:01Then, secure it with the elastic hook at the top, and you're golden.
29:07On the back of many makeup and hygiene products, you can find this symbol with a marking, like 6M, 12M,
29:15and 24M.
29:17This is the number of months this product can serve after you open it and before you should throw it
29:23out.
29:24The two sides of a cotton pad are different because each of them has a particular purpose.
29:30A cotton pad has several layers to ensure that it's soft, strong, and can absorb liquids.
29:37The edge is stitched to hold it all together.
29:40The smooth side of a pad is for applying products, like tonics and lotions.
29:45And the embossed side is best for cleansing and makeup removal.
29:50Also, any pack of cotton pads has those strings on the sides.
29:54They're there so you can hang the package somewhere.
29:58Then, you can open the package at the bottom, where the perforated line is, and take them out.
30:04Did you know that there is an efficient way to pull a thread from yarn?
30:08When you pull from the outside, the yarn rolls away, so you need to hold it.
30:13However, if you pull it from the center, it will stay together.
30:18We're all familiar with staplers, but I bet you don't know all its secrets.
30:23Most staplers have a compartment to store spare staples, which can be located either on top or at the bottom.
30:31Also, surprise!
30:32This metal plate you press staples against can be turned around.
30:36This way, the device will be able to staple your documents by turning the metal ends outwards.
30:43No need to wonder whether you need to get a smaller or bigger container.
30:47Turns out, plastic food containers have volume measurements on their bottoms, indicating how much food they can fit.
30:55Ceiling fans come with a small switch on the inside of the blade.
30:59You might not have noticed it because it's not in plain sight, so check yours out.
31:04This switch allows you to change the direction of rotation.
31:08Now, why would you want to do that?
31:10The blades of a fan push the air in different directions, depending on the way they rotate.
31:16In the summer, you need the air to be pushed down to create the effect of a breeze.
31:22In the winter, the direction should be changed so that the air is pushed towards the ceiling.
31:27It then heats up before going down the walls.
31:32Have you noticed that the gas tank sign on cars' dashboards has a little arrow next to it?
31:38Well, this arrow has a purpose.
31:41It points at the side of the car where the gas tank is located.
31:45It's very useful for forgetful people who constantly wonder where the gas tank is,
31:50and also for those who drive rentals once in a while.
31:53The answer is right in front of your eyes.
31:55If you can't find the arrow on your panel, then the fuel hose on the icon indicates the side instead.
32:04All car tires have 12-digit numbers printed on them,
32:07and they're actually important codes for car owners if they want to get the right tire.
32:13The first letter identifies the type of tire.
32:16P stands for a tire for light passenger cars, and LT is for heavy vehicles.
32:22Then, the following numbers stand for the width of the tire, its radial, and its diameter.
32:30Measuring tapes have that metal stud on the end,
32:33which you can use to attach the tape to the surface you measure.
32:36This way, you don't need to hold it yourself.
32:39But there's also a small slot, which can be used to hang the tape on a nail.
32:44Again, to free your hands and keep measuring.
32:48The bottom of the end of the tape has a ridged edge.
32:52It will help you make a mark if you don't have a marking tool with you.
32:56On the tape, there are black diamonds that are placed every 19.2 inches.
33:02They're useful for construction workers when spacing engineering joists.
33:07They can also be useful for you if you want to hang something heavy, for example.
33:12The diamond will mark the exact center of a wooden joist.
33:15Those are placed 16 inches apart from one another.
33:19There, you can drill something to that center to make sure whatever you hang is safely attached to the joist
33:25instead of the unreliable thin wall.
33:28Pictures will survive, but it's particularly important if you're hanging something heavy.
33:34Did you know that batteries have an expiration date?
33:38Yes, it's printed right on their label, but I've never noticed it before.
33:43The expiration date doesn't mean you can't use it after that.
33:47It's more like a recommended usage period, after which the manufacturer can't guarantee full battery life due to deteriorated components.
33:59These little feet keyboards have are actually a standard.
34:04The height of a keyboard should be adjustable, allowing the angle between 0 degrees and 15 degrees.
34:12The reason to fold the feet out is for you to see the keys better, in case you don't type
34:18blindly.
34:19A little problem that comes with it is that, in this case, your wrists are bent.
34:25And it's not good to keep them in this position for a long time.
34:30Pans have those holes on the ends of their handles.
34:34They're not just there for you to hang them.
34:36You can also place your cooking spoon in there.
34:39It'll hang right above the pan, and the sauce will not spill around.
34:45Make sure to tap off the sauce or food beforehand, though, so that it doesn't go down the spoon's handle.
34:53Stickers with numbers you can find on fruits can tell you some information on how the food was grown.
35:01A four-digit code that starts with a four means that the fruit was grown conventionally, meaning it contains chemicals
35:10and pesticides.
35:11So your best choice should be a fruit with a five-digit number.
35:16And if you see the number nine, it indicates that the fruit is certified organic.
35:23On the bottom of plastic bottles, you can often notice a mark of a triangle with a number engraved in
35:31the middle.
35:32This number specifies the type of plastic that was used to produce the bottle.
35:38These codes help people and local recycling centers to sort returns.
35:44Products that were made of plastic of types 1 and 2 are the easiest ones to recycle.
35:51Plastics of types 3 through 7 are tougher to recycle.
