00:00:01What's hiding inside Coca-Cola cans and regular household batteries?

00:00:05Why do magnets affect breakfast cereals?

00:00:08Do crosswalk buttons actually work or are they just useless decorations?

00:00:14What does that USB symbol really mean?

00:00:17I'm not sure I know the answers to these and similar questions,

00:00:21but I'm eager to learn the truth together with you.

00:00:24Let's find it out.

00:00:26Coca-Cola cans have a secret few people know about.

00:00:30Here's a Coke can.

00:00:31Let's submerge it in a highly corrosive alkaline solution.

00:00:35The aluminum dissolves due to a process known as hydrolysis,

00:00:39and we can see a plastic liner inside the can.

00:00:42It's made from a polymer or epoxy resin

00:00:45and serves as some kind of a protective barrier

00:00:48between the aluminum walls of the can and the rather acidic soda.

00:00:53Despite a popular myth, household batteries don't actually contain liquid,

00:00:58and if you accidentally cut them open, no toxic liquid will spill.

00:01:02Most of them are dry cell batteries which are made of electrochemical cells.

00:01:06Those convert chemical energy into electrical energy.

00:01:10Larger batteries often house numerous small cells within them too.

00:01:14Even Tesla vehicle batteries consist of multiple small cells.

00:01:18When combined, they easily provide the necessary voltage.

00:01:24Most toothbrushes have differently colored bristles,

00:01:27but they aren't just pleasing to the eye.

00:01:29Those bristles, often blue, have a functional purpose.

00:01:32They're called toothbrush indicators,

00:01:34and their colors fade as you use the brush.

00:01:37The American Dental Association recommends changing your toothbrush

00:01:40at least four times a year.

00:01:43And by getting paler,

00:01:44these bristles help you figure out when it's time to replace your toothbrush.

00:01:49You'll probably agree that there's no better snack than a pack of chips.

00:01:53Some are flat, others have ridges.

00:01:55Is it just aesthetics?

00:01:57Not really.

00:01:58The main purpose of those lines on some kinds of chips

00:02:01is to help with the distribution of spices and seasonings.

00:02:04In other words,

00:02:05all those substances that make your chips taste like cheese

00:02:08are mostly stored inside the lines.

00:02:11Plus, the lines make chips crunchier.

00:02:15Now, this one might be a surprise,

00:02:17but some breakfast cereals are magnetic.

00:02:19That's because they're often fortified with iron

00:02:22in the form of a fine powder.

00:02:24Due to the added iron,

00:02:26cereal flakes get attracted to magnets.

00:02:28All this may sound kind of alarming,

00:02:30but in reality,

00:02:31the iron content in the flakes is minimal

00:02:33and doesn't pose any threat to your health.

00:02:37That clear fluid in gel pens

00:02:38is called the ink follower or stopper fluid.

00:02:41The gel in such pens contains pigment particles

00:02:44dissolved in a polymer solution.

00:02:47The main task of the stopper fluid

00:02:49is to be a barrier

00:02:50to prevent the gel from evaporating or leaking out.

00:02:53Without this transparent fluid,

00:02:55your gel pen wouldn't function.

00:02:58The fluid always stays in one position

00:03:00and doesn't get dissolved with the gel.

00:03:02Neither does it move backwards

00:03:04or flow out of the pen.

00:03:07Many pedestrian crosswalk buttons,

00:03:09namely in New York,

00:03:11are placebo buttons.

00:03:12They do literally nothing when you press them.

00:03:15Originally, they were functional

00:03:17after being introduced in 1964,

00:03:19but today,

00:03:20most of them don't affect traffic lights,

00:03:22which are programmed

00:03:22based on the real needs of the traffic flow.

00:03:26Why do such buttons even exist then?

00:03:28It's a simple psychological trick,

00:03:30providing you with an illusion of control.

00:03:34You might have noticed

00:03:35that movie theater seats

00:03:36are almost always red.

00:03:39This choice isn't random.

00:03:40It has strategic importance,

00:03:42which is rooted in visual science.

00:03:44The thing is,

00:03:46red light has a longer wavelength.

00:03:47It means that it's the first color

00:03:49to disappear in low light.

00:03:51It allows the audience

00:03:52to concentrate better on the screen

00:03:53once the movie begins.

00:03:55Such a design choice

00:03:56enhances the viewing experience

00:03:58by minimizing distractions.

00:04:01Speed bumps are crucial

00:04:02for pedestrian safety,

00:04:04but at the same time,

00:04:05they can seriously increase car emissions

00:04:07due to the non-stop acceleration

00:04:09and deceleration they cause.

00:04:13To address this issue,

00:04:14some cities like London

00:04:15are testing fake speed bumps.

00:04:17Those are optical illusions

00:04:19painted on the road.

00:04:20They look raised

00:04:22from a driver's perspective,

00:04:23but in reality,

00:04:24they're flat.

00:04:25Authorities hope that this approach

00:04:27will slow down drivers

00:04:28without having a negative impact

00:04:30on the environment.

00:04:33Soda bottles are always filled

00:04:35in such a way

00:04:36that there's some space

00:04:37between the liquid and the cap.

00:04:39That's because soda contains

00:04:40carbon dioxide.

00:04:41It's a gas that can expand

00:04:43once the bottle's heated.

00:04:44If there's no gap in the bottle,

00:04:46it can break

00:04:47because of the pressure

00:04:48building inside.

00:04:50Also, when you open your drink,

00:04:52the gases go out

00:04:52in the form of bubbles,

00:04:54making the drink overflow.

00:04:55The gap helps

00:04:57with this problem, too.

00:05:00The USB symbol,

00:05:01looking like a trident,

00:05:03has always sparked

00:05:04multiple speculations

00:05:05about its origin.

00:05:07One popular idea

00:05:08is that it represents

00:05:09Neptune's trident

00:05:11and symbolizes power

00:05:12and adaptability.

00:05:13But there's also

00:05:14a little bit less

00:05:16exciting theory.

00:05:17A man who claimed

00:05:18to have designed the symbol

00:05:19in the 1980s

00:05:20stated that it was supposed

00:05:21to represent connectivity.

00:05:23The large circle

00:05:24symbolizes a computer,

00:05:26while the attached shapes

00:05:27– the circle,

00:05:28the triangle,

00:05:29and square –

00:05:29stand for different outputs.

00:05:33The design of a tennis racket

00:05:35has a specific feature

00:05:36known as the throat.

00:05:38It's an open space

00:05:39below the head of the racket.

00:05:41This space isn't just

00:05:43for storing balls,

00:05:44it also improves

00:05:45the racket's aerodynamics

00:05:46by letting air pass through.

00:05:48It seriously reduces drag

00:05:50during swings.

00:05:52Speaking of tennis,

00:05:54tennis courts are usually

00:05:55built with a north-south

00:05:56orientation.

00:05:58It helps minimize

00:05:59the impact of the sun's

00:06:00position during the game,

00:06:01ensuring that neither player

00:06:03has the sun directly

00:06:04in their eyes.

00:06:06Look closely

00:06:07at a tram's overhead lines

00:06:09and you'll see

00:06:10that its contact wires

00:06:11zigzag back and forth

00:06:13instead of going

00:06:13in a straight line.

00:06:15That's because all trams

00:06:16have pantographs

00:06:17attached to their roofs.

00:06:19The upper part

00:06:20of the pantograph

00:06:21is gradually worn down

00:06:22by the overhead wire

00:06:23and eventually

00:06:24needs to be replaced.

00:06:26To wear it down evenly,

00:06:28the wire is not installed

00:06:29strictly along the tram's path,

00:06:32but in zigzag patterns.

00:06:34As the tram moves,

00:06:35the pantograph slides

00:06:37along the wire

00:06:37and it wears down evenly.

00:06:41Those cone-shaped

00:06:42water cooler cups?

00:06:44Their shape is

00:06:45intentionally designed

00:06:46to prevent users

00:06:47from setting the cups down.

00:06:48This allows employees

00:06:50to minimize the risk

00:06:51of spilling water

00:06:52on their desks

00:06:53around various

00:06:53electronic devices.

00:06:55Plus,

00:06:56less material is used

00:06:57to produce cone-shaped cups,

00:06:58which makes the process

00:06:59less wasteful

00:07:00and more cost-effective.

00:07:02It also kind of

00:07:04supports sustainability

00:07:05by encouraging people

00:07:06to drink their water quickly

00:07:07and dispose of their cups

00:07:08immediately after.

00:07:12Most suitcases

00:07:13have two zipper pulls,

00:07:14and it serves

00:07:15several purposes.

00:07:17First of all,

00:07:18if one zipper fails,

00:07:20the other can keep

00:07:21the suitcase closed.

00:07:22Even better,

00:07:23having two zippers

00:07:24allows you to have

00:07:25easier access

00:07:26to small sections

00:07:27of your suitcase

00:07:28without having to

00:07:29open it entirely.

00:07:31And finally,

00:07:32when you have two zippers,

00:07:33you can connect them

00:07:35with a padlock

00:07:35for increased security.

00:07:39Some plastic milk containers

00:07:41have dents on their sides.

00:07:42These dents

00:07:43serve several purposes.

00:07:45When milk spoils,

00:07:46it usually causes swelling

00:07:48and high-pressure buildup

00:07:49inside the container.

00:07:50That's when the dent

00:07:51pops out

00:07:52and doesn't let

00:07:52the jug blow up.

00:07:54Plus,

00:07:55if you decide

00:07:55to freeze the milk,

00:07:56it will expand

00:07:57like any other fluid.

00:07:59And then again,

00:08:00the indentation

00:08:01will pop out

00:08:02and prevent the container

00:08:03from breaking

00:08:04inside your freezer.

00:08:07If you ever had

00:08:08a problem figuring out

00:08:09why fake pockets exist,

00:08:11you need to hear this.

00:08:13The main reason

00:08:14is that if a clothing item

00:08:16has a specific cut

00:08:17or shape,

00:08:18pockets may spoil it.

00:08:19They can alter

00:08:20the item's shape

00:08:21either in the warehouse

00:08:22or already on the retail rack.

00:08:24The solution?

00:08:26Getting rid of the pockets

00:08:27in key areas.

00:08:28Plus,

00:08:29fake pockets

00:08:30are obviously cheaper

00:08:31and they don't get

00:08:32stretched out.

00:08:34The thermos

00:08:35wasn't actually invented

00:08:37to keep your coffee warm.

00:08:39It was made

00:08:40by a Scottish scientist

00:08:41who wanted a safe place

00:08:42to keep his chemicals

00:08:43at a stable temperature.

00:08:45So,

00:08:46he took two bottles,

00:08:47put the smaller one

00:08:48inside the bigger bottle,

00:08:49and vacuumed out

00:08:50the air between them.

00:08:55We know how much

00:08:56homeowners love

00:08:57to make their houses

00:08:58picture perfect.

00:08:59It can soon become

00:09:00a struggle though

00:09:01once you've tried

00:09:02to flatten out

00:09:03those pesky corners

00:09:04of a new rug.

00:09:05But there is

00:09:06one genius trick

00:09:07that can help.

00:09:08Just plop a few ice cubes

00:09:09and a heavy object

00:09:10on the corner

00:09:11and voila!

00:09:12Flat rug.

00:09:13No more tripping

00:09:14over the rolled up edges.

00:09:17Sitting in your car

00:09:18frozen and grumpy,

00:09:20watching your window

00:09:20slowly defrost

00:09:21is about as fun

00:09:22as watching paint dry.

00:09:24And let's not forget

00:09:26the disaster

00:09:26that is wiping the mist

00:09:28off the inside.

00:09:29But hey,

00:09:29if you don't want to risk

00:09:30getting slapped with a fine,

00:09:32you better give this

00:09:33funky demisting trick

00:09:34a try.

00:09:35People have tried it all,

00:09:36but apparently,

00:09:37it was the cat litter

00:09:38that won the condensation game.

00:09:40Just grab an old sock

00:09:42or pair of tights.

00:09:43Fill them up

00:09:44with cat litter.

00:09:45Tie it up

00:09:46and plop it

00:09:46under your car's windows.

00:09:48It's so effective

00:09:49that it should do the trick

00:09:50in just 10 minutes.

00:09:52The cat litter works

00:09:53by absorbing the moisture

00:09:54in the air.

00:09:56Cleaning our stoves

00:09:57ain't fun either,

00:09:58let's be honest.

00:09:59But fear not,

00:10:00because one cleaning guru

00:10:02on TikTok

00:10:02has come to the rescue

00:10:04with a genius trick

00:10:05that'll make cleaning

00:10:06your stove a breeze.

00:10:08All you need

00:10:09is some oven spray,

00:10:10cling film,

00:10:11and a lot of patience.

00:10:12Start by spraying

00:10:14some cleaning product

00:10:15on the stove.

00:10:16Then cover the whole thing

00:10:17in cling film.

00:10:19Here's where your patience

00:10:20will be needed.

00:10:21You'll have to wait

00:10:21a whole day

00:10:22for the cleaning product

00:10:23to work its magic.

00:10:24But trust me,

00:10:25once you remove

00:10:26that cling film,

00:10:27the stains will have

00:10:28melted off.

00:10:29That leftover mess

00:10:31on your stove

00:10:31can be scrubbed off

00:10:32easily now.

00:10:34Finish the job

00:10:34using a regular cloth

00:10:36for the rest of the grind.

00:10:38It's time you forget

00:10:39about fancy schmancy

00:10:41car trash cans.

00:10:42Why waste your money

00:10:43on those

00:10:43when you can repurpose

00:10:45a plastic cereal container?

00:10:47It's small enough

00:10:48to fit in your car

00:10:49and the flip-top opening

00:10:50means your trash

00:10:51won't go flying

00:10:52all over the place

00:10:53when you take sharp turns.

00:10:55Plus,

00:10:55just line it

00:10:56with a plastic grocery bag

00:10:57and you're ready to go.

00:11:00Feel like your feet

00:11:01need a bit of pampering?

00:11:03You can skip

00:11:04the expensive spa day

00:11:05at your local salon.

00:11:06All you need

00:11:07is a sanitary pad,

00:11:09some toothpaste,

00:11:09and baking soda.

00:11:11Mix the toothpaste

00:11:12with the baking soda powder

00:11:14and spread it evenly

00:11:15on the pad.

00:11:16Place it on the soles

00:11:17of your feet

00:11:18and slip a sock on

00:11:19so it's nice and snuggly.

00:11:21The pad should keep

00:11:22the mixture and moisture in

00:11:24so you don't make a mess

00:11:25all over your house.

00:11:27After an hour or two,

00:11:28rinse off the toothpaste mixture

00:11:30with plenty of water.

00:11:32You'll notice how soft

00:11:33the soles of your feet

00:11:34have become.

00:11:35For that extra step,

00:11:37add some moisturizer too.

00:11:39Those trusty sanitary pads

00:11:41can be used for all sorts of stuff

00:11:43around your house too,

00:11:44like for freshening up

00:11:46your drawers.

00:11:47Just spritz some perfume

00:11:49on a pad.

00:11:50Place it next to your clothes

00:11:51of choice and voila!

00:11:53Your gym clothes,

00:11:54for example,

00:11:54will smell like

00:11:55a fragrant bouquet.

00:11:56And don't forget

00:11:57to throw one

00:11:58in your gym bag too.

00:12:00Oh boy,

00:12:02time to give those lampshades

00:12:03the love they deserve.

00:12:04Grab a trusty lint roller

00:12:06and watch in amazement

00:12:07as you unveil

00:12:08a whole new world of colors

00:12:09underneath that forever dust.

00:12:12Who knew your lampshades

00:12:13were secretly chameleon?

00:12:16Say goodbye to dog hair

00:12:18and hello to your

00:12:19new household best friend,

00:12:20the rubber squeegee brush.

00:12:22This bad boy can snatch up

00:12:24so much fur from your carpet

00:12:25that you'll be wondering

00:12:26if you even own a pet.

00:12:28Just stroke it short

00:12:30and quick over your rug

00:12:31and watch it unleash

00:12:32a furry storm.

00:12:34And if you're wondering

00:12:35about your hardwood floors,

00:12:36fear not.

00:12:37The rubber bristles

00:12:38work like magic

00:12:39to create one giant fur ball.

00:12:43Save yourself

00:12:44from cleaning cabinets

00:12:45and furniture tops

00:12:46by hooking them up

00:12:47with fashionable hats.

00:12:49They're made out of wax paper

00:12:51or paper bags.

00:12:52The dirt and grease

00:12:53will stick to your new accessories

00:12:55and when it's time

00:12:56for a new look,

00:12:57just swap them out

00:12:58every few months.

00:13:00You know that feeling

00:13:01when you finally peel off

00:13:02a bumper sticker

00:13:03or parking permit,

00:13:04but then you're left

00:13:05with a sticky mess?

00:13:06There's a simple solution though.

00:13:08Slap a wet piece of newspaper

00:13:10on top of that gunk

00:13:12and let it marinate

00:13:12for 15 minutes.

00:13:14Then poof!

00:13:15The glue will be as soft

00:13:16as a fluffy cloud

00:13:17and you can wipe it away

00:13:19with ease.

00:13:20If your dishwasher

00:13:22is stinking up your kitchen,

00:13:23it's time to get

00:13:24your detective hat on.

00:13:25Check that filter

00:13:26for any leftovers

00:13:27lurking in there.

00:13:28Then add a splash of vinegar

00:13:30to your next hot wash cycle.

00:13:32Those pesky food particles

00:13:34could be the culprits

00:13:35behind your dishwasher's

00:13:36funky fragrance.

00:13:38Get ready to be

00:13:39a Vaseline wizard.

00:13:41Say goodbye to pesky

00:13:42polish smudges

00:13:43with a simple solution.

00:13:45Slather some Vaseline

00:13:46around your nails

00:13:47before you go to town

00:13:48with a brush.

00:13:50Once you're done,

00:13:51wipe away the excess

00:13:52without the need

00:13:53for any nail polish remover.

00:13:55And if you're feeling fancy,

00:13:57make that perfume

00:13:57last even longer

00:13:58by adding a touch

00:13:59of Vaseline

00:14:00to your neck and wrists.

00:14:02It's like a scent superhero,

00:14:04keeping those fragrance molecules

00:14:06from flying away too soon.

00:14:09Have you checked out

00:14:10your shower curtain lately?

00:14:11It might be looking

00:14:12pretty grimy and gross.

00:14:13Toss that bad boy

00:14:15in the washing machine

00:14:16with a couple of towels

00:14:17and voila,

00:14:18no more soap scum stains.

00:14:20The towels will help

00:14:22with scrubbing away

00:14:23all that mess

00:14:24while they're tumbling

00:14:24in the washing machine.

00:14:26Say goodbye to single socks

00:14:29with a strip of foam pipe insulation.

00:14:31Measure and cut each piece,

00:14:33then place it in that sneaky gap

00:14:35between your washer and dryer

00:14:37or wall.

00:14:38Those pesky socks

00:14:39will never go missing again.

00:14:42Got a wobbly table

00:14:44that's cramping your style?

00:14:46Your trusty bottle cork

00:14:48is here to save the day.

00:14:50Slice off a piece

00:14:51of that bad boy,

00:14:53glue it to the wobbly leg,

00:14:55and voila!

00:14:56You've got yourself

00:14:57a sturdy surface

00:14:58to rest your drink on.

00:15:01A hammer is more

00:15:03than just a smashing tool.

00:15:05The back of this tool

00:15:07can actually hold

00:15:08a nail for you.

00:15:10No more risking your fingers

00:15:12or giving yourself

00:15:14a thumbectomy.

00:15:15Just slide it into the claw

00:15:17and bam!

00:15:18You're ready to nail it.

00:15:21Want to know the saucy way

00:15:23to pick up a sizzling lid?

00:15:25Ditch those boring oven mitts

00:15:27and grab yourself

00:15:28a pair of tongs.

00:15:30But wait!

00:15:31Don't just go in head first.

00:15:33Use the middle.

00:15:35Trust me,

00:15:36it's hot

00:15:37and it's effective.

00:15:39Care to find out

00:15:40how to keep

00:15:41your dressing gown

00:15:42from slipping

00:15:43and sliding

00:15:44all over the place?

00:15:46Got you covered!

00:15:47Instead of going

00:15:48through all the loops,

00:15:50just place the cord

00:15:51through the front ones.

00:15:53You don't even need it

00:15:54to be wrapped around you.

00:15:56All the business

00:15:57will be in the front.

00:16:00Tie that cord up

00:16:01nice and tight

00:16:02and you'll be strutting around

00:16:04in no time.

00:16:06Bet you didn't know

00:16:08the right way

00:16:08to light a multi-wit candle.

00:16:11You'll never hurt

00:16:12the tips of your fingers

00:16:13again.

00:16:15Truth is,

00:16:16you don't light them

00:16:17one by one.

00:16:18Just light the first one.

00:16:20Then angle the candle

00:16:22in the right position

00:16:23so it lights up

00:16:24the other ones too.

00:16:27So,

00:16:28apparently,

00:16:29we've all been

00:16:30using deodorant wrong.

00:16:32Who knew?

00:16:34You're supposed to

00:16:35lather that stuff on

00:16:36before going to bed.

00:16:39That's because

00:16:40our underarms

00:16:41are supposed to

00:16:42soak it in overnight

00:16:43for maximum effectiveness.

00:16:47I'm here to save you

00:16:48from the USB struggle bus.

00:16:50You know that symbol

00:16:52on the cord?

00:16:53Yeah,

00:16:54it's not just there

00:16:55for decoration.

00:16:56Align the seam

00:16:57with the opposite edge

00:16:58of the tongue

00:16:59and voila,

00:17:00you're in business.

00:17:02No more flipping it

00:17:03upside down

00:17:03and sideways

00:17:04like a crazy person.

00:17:06Thank me later.

00:17:07Hey, buddy.

00:17:08Looks like you had

00:17:09some fun

00:17:09in the great outdoors.

00:17:12As adorable

00:17:13as those paw prints look,

00:17:14your mama

00:17:15still needs to clean them.

00:17:18Spreading soda

00:17:19over the carpet

00:17:20and then vacuuming it

00:17:21works like magic

00:17:22for such cases.

00:17:26Artistic people

00:17:26can be messy sometimes.

00:17:28No judgment here.

00:17:30I know it's all part

00:17:31of the creative process.

00:17:33But this hack

00:17:34will actually help

00:17:35save time

00:17:36from cleaning

00:17:36only to paint more.

00:17:39I think that's more

00:17:40than enough

00:17:41laundry detergent.

00:17:43Yep,

00:17:44she agrees with me.

00:17:45There's a way

00:17:46to make sure

00:17:47he uses the right

00:17:48amount next time.

00:17:50Just put the ice tray

00:17:51in the freezer

00:17:52and you'll have yourself

00:17:53jelly detergent cubes.

00:17:57Hey,

00:17:58this'll save you

00:17:59money too,

00:17:59you know.

00:18:00Cleaning your brushes

00:18:01is such a bore.

00:18:03It's definitely

00:18:04something that

00:18:05tests one's patience.

00:18:08This shaving foam hack

00:18:09will save you

00:18:09a lot of time.

00:18:11I feel like

00:18:12that amount of hair

00:18:13will clog the sink though.

00:18:15Remember what

00:18:16parents always say,

00:18:17wash your hands

00:18:18before eating something.

00:18:22But looks like

00:18:23that's not an easy task

00:18:24with those melted soap bars.

00:18:27A couple of rubber bands

00:18:29will help you

00:18:29save your soap.

00:18:33It won't be touching

00:18:34water all the time

00:18:35and therefore

00:18:36it'll last longer.

00:18:39Oh man,

00:18:40I hate it

00:18:41when bottles

00:18:42get all dirty inside.

00:18:44If you're not

00:18:45Mr. Fantastic

00:18:46with the ability

00:18:47to stretch your body

00:18:47into any shape,

00:18:49then this looks like

00:18:49an impossible task.

00:18:53Hey,

00:18:54wait,

00:18:54maybe I was looking

00:18:56at it the wrong way.

00:18:57Magneto's powers

00:18:58will work perfectly fine here.

00:19:01I feel like

00:19:02you'll need

00:19:02a stronger magnet,

00:19:03however.

00:19:04Wow,

00:19:05this bottle

00:19:06looks brand new now.

00:19:07Don't you just hate

00:19:08that cooking and cleaning

00:19:09takes forever,

00:19:10but eating the dish

00:19:11you made

00:19:12takes like 15 minutes?

00:19:16Guess that guy

00:19:17leaves all the hard work

00:19:18to the lady.

00:19:20Don't worry, miss.

00:19:22There's a way

00:19:22you can avoid

00:19:23this disaster.

00:19:25Just cover the surfaces

00:19:27with stretch film

00:19:28and that's it.

00:19:29Now,

00:19:30you don't need

00:19:30to get anxious

00:19:31about all the cleaning

00:19:32you'll have to do later.

00:19:35Hope this won't cause you

00:19:37to be late

00:19:37for your work

00:19:39because how are you

00:19:41going to explain

00:19:41this to your boss?

00:19:44You can't just say

00:19:45I had to wait

00:19:46for the stinky odor

00:19:47to go away.

00:19:50It's always a real struggle

00:19:52to get the corners,

00:19:53am I right?

00:19:55But it's nothing

00:19:56a couple of straws

00:19:57can't fix.

00:19:59No dust left behind

00:20:01is the motto.

00:20:02You can firmly clean

00:20:03all the nooks and crannies

00:20:05that the regular vacuum

00:20:06head can't get to.

00:20:10If you're a jar collector

00:20:12like I am,

00:20:12then you already got

00:20:13everything you'll need

00:20:14for this hack.

00:20:18This is what being smart

00:20:20looks like, everyone.

00:20:21By the way,

00:20:22looks like you've been

00:20:23postponing doing the dishes

00:20:24for a while now, huh?

00:20:28Don't worry,

00:20:29no judgments.

00:20:30We've all been there.

00:20:32Those toothbrushes

00:20:33were basically

00:20:34swimming in there.

00:20:36But the glass

00:20:37filling up with water

00:20:38is inevitable,

00:20:39really.

00:20:40However,

00:20:41Orbeez balls

00:20:42can make the process

00:20:43a lot slower.

00:20:45Somebody needs to

00:20:46replace the paper towel.

00:20:49But don't head to the store

00:20:51just yet.

00:20:52I suggest you

00:20:53ditch paper towels

00:20:54altogether

00:20:54and go for this

00:20:55reusable option.

00:20:58You'll be saving

00:20:59a lot of bucks.

00:21:00Thank me later.

00:21:02Whoa,

00:21:03have you been collecting

00:21:04dirty makeup sponges

00:21:05or what?

00:21:07Don't use them

00:21:08until they're all clean.

00:21:10Otherwise,

00:21:11I'm pretty sure

00:21:11they'll give you pimples.

00:21:14Looks like this

00:21:15is gonna take a while.

00:21:17But the satisfaction

00:21:18you'll get

00:21:19once you see them

00:21:20all clean

00:21:21will be worth it.

00:21:23These kind of look

00:21:24like Easter eggs

00:21:25to me.

00:21:26By the way,

00:21:27do you really need

00:21:28that many sponges

00:21:29to do your makeup?

00:21:32It's all fun and games

00:21:34until someone spills

00:21:35all the glitter

00:21:35on the floor.

00:21:38Worry not,

00:21:38we got you.

00:21:40Hey,

00:21:40good to see you recycling.

00:21:42No,

00:21:43you don't need

00:21:44a bigger bin,

00:21:44trust me.

00:21:45All you need

00:21:46is to know

00:21:47this one hack.

00:21:48And let's get

00:21:49this one thing straight.

00:21:50I know this is science

00:21:51but it sure feels

00:21:52like magic.

00:21:55Honey,

00:21:56I shrunk the trash.

00:21:58Look at the difference here.

00:22:00It's a relief

00:22:01to see you don't have

00:22:02a pile of dirty dishes

00:22:03like the lady before.

00:22:05But how are you

00:22:06going to explain

00:22:07that sink?

00:22:08Seems like you've

00:22:09been ignoring it

00:22:10for quite some time now.

00:22:13That's why you need

00:22:14something strong

00:22:15to scrub there.

00:22:18But I have

00:22:19a better solution,

00:22:21one that won't

00:22:21tire you.

00:22:23Just apply a coat

00:22:24of dish soap

00:22:25and soda mixture

00:22:26all around the sink

00:22:27and wait.

00:22:29I wouldn't believe

00:22:30how it works wonders

00:22:31if I didn't see it

00:22:32with my own eyes.

00:22:35You're going to hurt

00:22:36your back and knees

00:22:37cleaning like this.

00:22:40You know,

00:22:41robot vacuum cleaners

00:22:42don't need coffee breaks,

00:22:43right?

00:22:45So put that thing

00:22:46to work.

00:22:47In the meantime,

00:22:49you can just relax

00:22:49and maybe even start

00:22:50reading the book

00:22:51you bought six months ago.

00:22:55No matter how many times

00:22:56you clean the stove,

00:22:57it always gets dirty

00:22:59at the end of the day,

00:23:00right?

00:23:02Well,

00:23:03not anymore.

00:23:04Hey,

00:23:05I think I'm going to

00:23:06give this a try

00:23:06using glitter glue.

00:23:07It'll help make

00:23:08things more fun.

00:23:11You should have

00:23:12bought a trash bin

00:23:13with a lid

00:23:14to avoid the awful

00:23:15stench, you know.

00:23:18Although this hack

00:23:18won't make the trash

00:23:19smell good or anything,

00:23:20it will at least

00:23:21help keep your bin

00:23:22fresh and nice.

00:23:26I know this is not

00:23:28a food hacks video,

00:23:29but that doesn't stop me

00:23:30from wanting some snacks now.

00:23:33Even if you're too old

00:23:34to play with slimes,

00:23:35it might be a good idea

00:23:36to keep one at home

00:23:37for stuff like this.

00:23:46If I were you,

00:23:47I would still disinfect

00:23:48that with antibacterial wipes

00:23:50or something,

00:23:51just in case.

00:23:53Hey,

00:23:54it's her turn

00:23:54to pick the movie now.

00:23:56Uh-oh,

00:23:57someone's forgotten

00:23:58to add laundry powder

00:23:59to the shopping list.

00:24:01That's okay,

00:24:02you can still make

00:24:03your own

00:24:04with everyday things

00:24:05such as baking soda

00:24:06and a soap bar.

00:24:08This lady is one

00:24:10of the lucky ones

00:24:10because she has

00:24:11a dishwasher.

00:24:13Placing a piece

00:24:14of lemon,

00:24:15even one that's

00:24:16been juiced,

00:24:16will help freshen

00:24:17the load

00:24:17and leave your dishes

00:24:18looking shinier.

00:24:22This is why

00:24:23I never wear

00:24:24white socks

00:24:24if I'm going

00:24:25to visit

00:24:25someone else's house.

00:24:28Because I don't

00:24:29really want to see

00:24:30how dirty

00:24:30their floors

00:24:31might be,

00:24:31you know?

00:24:35Using bleach

00:24:36for situations

00:24:36like this

00:24:37may help,

00:24:38but it might

00:24:38also ruin

00:24:39your garments.

00:24:41That's why

00:24:42this hack

00:24:42is the better option

00:24:43to make white clothes

00:24:44look great again.

00:24:47You might want

00:24:48to clean the microwave

00:24:49after you're done though.

00:24:52This phone case

00:24:53looks like it's

00:24:54been through

00:24:54some tough stuff.

00:24:57Let's give it

00:24:58the second chance

00:24:59it deserves.

00:25:00All you need

00:25:01to do is apply

00:25:02WD-40 spray,

00:25:03pour some soda

00:25:04and rinse it out.

00:25:06By the way,

00:25:07if you have

00:25:08sensitive skin,

00:25:08you might want

00:25:09to wear protective gloves

00:25:10to avoid irritation.

00:25:13Better safe

00:25:14than sorry.

00:25:15Cleaning stubborn

00:25:16stains on a glass

00:25:17stovetop

00:25:18can be tricky.

00:25:20There's always

00:25:21the risk

00:25:21of causing

00:25:22scratches

00:25:22on the surface.

00:25:25That's why

00:25:26any type of

00:25:27scrubbing

00:25:27or scraping

00:25:28action

00:25:28is not advised.

00:25:30Did you know

00:25:31that according

00:25:32to one poll,

00:25:33an average person

00:25:34spends more than

00:25:34six days a year

00:25:35washing dishes?

00:25:38Then there's

00:25:39all the other

00:25:40cleaning stuff

00:25:40that needs to be done.

00:25:43But knowing

00:25:44the right hacks

00:25:45will save you

00:25:45a lot of time

00:25:46and make your life

00:25:47so much easier.

00:25:50Wow,

00:25:51your shoes

00:25:51are definitely

00:25:52cleaner than

00:25:53this house.

00:25:54Who knew

00:25:55shoelaces would

00:25:56work like a charm

00:25:56when it comes

00:25:57to getting rid

00:25:57of all the dust

00:25:58and rust?

00:26:01Is it time

00:26:02to go to bed yet

00:26:03or are you tired

00:26:04of all the work

00:26:05you've done

00:26:05around the house?

00:26:08I was being

00:26:09sarcastic.

00:26:10Your partner

00:26:11did all the work.

00:26:12So saving her

00:26:13toothbrush

00:26:14is the least

00:26:15you can do.

00:26:16Even when you

00:26:17listen to the

00:26:18instructions

00:26:18and create a

00:26:19strong password

00:26:20for any of

00:26:20your online

00:26:21accounts,

00:26:22you're still

00:26:22not entirely

00:26:23safe from hackers.

00:26:25They always

00:26:26come up with

00:26:27new ways

00:26:27to crack

00:26:28what you think

00:26:29might finally

00:26:30be a good

00:26:31and secure

00:26:31password.

00:26:32For example,

00:26:34there's a

00:26:34password manager

00:26:35tool that has

00:26:36taken a look

00:26:37at more than

00:26:3760 million

00:26:38passwords

00:26:39from data

00:26:39breaches.

00:26:42It turns out

00:26:43the majority

00:26:43of people

00:26:44choose passwords

00:26:45that aren't

00:26:46that unique.

00:26:47I love you,

00:26:48Ferrari,

00:26:49and password1234

00:26:51are some of the

00:26:52most popular ones

00:26:53together with

00:26:54Star Wars.

00:26:56For hackers,

00:26:57these are really

00:26:58not difficult

00:26:58to guess.

00:26:59Plus,

00:27:00they have special

00:27:01tools that help

00:27:02them with cracking

00:27:02passwords.

00:27:05For example,

00:27:07one takes a list

00:27:08of dictionary

00:27:08words and then

00:27:09uses them to

00:27:10find out

00:27:11passwords.

00:27:12With this tool,

00:27:13you can try

00:27:13millions of words

00:27:14in a pretty

00:27:15short time.

00:27:16It's able to do

00:27:17some sneaky

00:27:18things, too,

00:27:19such as replacing

00:27:20an E with

00:27:213 or an A

00:27:23with an

00:27:24at sign.

00:27:27This tool also

00:27:28noticed that

00:27:28there were a lot

00:27:29of people who

00:27:30believed they

00:27:30were unique and

00:27:31creative with

00:27:32their passwords

00:27:33because they

00:27:34used a tactic

00:27:35we call

00:27:35password walking.

00:27:37It's when your

00:27:38fingers walk

00:27:39across the

00:27:40keyboard,

00:27:40and you create

00:27:41a password using

00:27:42keys that are

00:27:43next to each

00:27:44other.

00:27:44For example,

00:27:46QWERTY or

00:27:48ASDFG.

00:27:49It may seem

00:27:50meaningless enough

00:27:51to be safe,

00:27:51but you're not

00:27:52the only one

00:27:53who's thought of

00:27:54it, and

00:27:55hackers know

00:27:56it.

00:27:56They can upload

00:27:57basically any

00:27:58number of different

00:27:59variations into

00:28:00some of their

00:28:00tools to test

00:28:01them out.

00:28:02So it's just

00:28:03a matter of

00:28:04time before

00:28:04they find out

00:28:05what your

00:28:06password is.

00:28:12Here's a big

00:28:13no-no.

00:28:14Using the same

00:28:15password for

00:28:15multiple websites.

00:28:17Hackers love

00:28:18when you do that

00:28:19because once they

00:28:20figure out one

00:28:20password, they

00:28:21can use it to

00:28:22access all your

00:28:23other accounts,

00:28:24too.

00:28:25Let's say your

00:28:26base password is

00:28:27Porsche.

00:28:28Then you add a

00:28:29few numbers and

00:28:30symbols to the

00:28:31end to create a

00:28:32unique password for

00:28:33each site you

00:28:33use, like

00:28:35Porsche 3%5% for

00:28:38Facebook or

00:28:40Porsche 5$7% for

00:28:43Twitter.

00:28:46Most of us use

00:28:47the same principle

00:28:48at some point.

00:28:49The thing is that

00:28:50hackers are not

00:28:51going for your bank

00:28:52account or work

00:28:53VPN first, even

00:28:55though one of the

00:28:56main goals is to

00:28:57get there.

00:28:58They'll use their

00:28:59special tools to

00:29:00try out lots and

00:29:01lots of different

00:29:02usernames and

00:29:03passwords on

00:29:04websites that

00:29:05might not have

00:29:06the best security,

00:29:07such as an

00:29:07online forum you

00:29:09often visit, or

00:29:10maybe an e-commerce

00:29:11site where you've

00:29:12had some shopping

00:29:13lately.

00:29:15All they have to

00:29:16do is try

00:29:17different variations

00:29:18of your base

00:29:19password, like

00:29:20Porsche 1 or

00:29:22Porsche 123, and

00:29:24sooner or later,

00:29:25they'll crack the

00:29:26code and gain

00:29:27access to all

00:29:28your accounts.

00:29:29And if they get

00:29:30lucky and guess

00:29:31your login info for

00:29:32one of those sites,

00:29:34they can then use

00:29:35that info to try

00:29:36and access more

00:29:37important sites.

00:29:40And we're not

00:29:41talking about some

00:29:42genius hackers here.

00:29:44They use simple

00:29:45tricks, like

00:29:46checking your

00:29:46social media

00:29:47profiles.

00:29:48If you've ever

00:29:49mentioned your

00:29:50dog's name or

00:29:51your kid's birth

00:29:52date on Facebook,

00:29:53for example, a

00:29:54hacker could use

00:29:55that info to

00:29:56guess your

00:29:56passwords.

00:29:57So, chappy123 is

00:30:00out.

00:30:02So what's the

00:30:03solution here?

00:30:04First, stop trying

00:30:05to come up with

00:30:06some unique

00:30:07passwords based on

00:30:08things in your

00:30:09life.

00:30:10Instead, use a

00:30:11password manager to

00:30:12generate strong,

00:30:13random passwords for

00:30:15all your accounts.

00:30:16And make sure those

00:30:17passwords are long and

00:30:19include a variety of

00:30:20characters, not just

00:30:22lowercase letters.

00:30:24Plus, it's much

00:30:26safer to create unique

00:30:27random passwords for

00:30:29each site you use.

00:30:30That way, even if a

00:30:31hacker does manage to

00:30:33crack one of your

00:30:34passwords, they won't

00:30:35be able to access all

00:30:36your other accounts as

00:30:38well.

00:30:38And you won't have to

00:30:39remember all those

00:30:40crazy passwords yourself.

00:30:42The password manager

00:30:43will do it for you.

00:30:47Also, it's better to

00:30:49have a long password.

00:30:51The tools hackers use

00:30:52crack shorter passwords

00:30:54with lowercase letters

00:30:55way faster.

00:30:56If you add only one

00:30:58asterisk and one

00:30:59capital letter, it

00:31:01will change the

00:31:01processing time for,

00:31:03let's say, a

00:31:04password with eight

00:31:05characters from 2.4

00:31:06days to 2.1

00:31:08centuries.

00:31:11Here's another scam

00:31:13they use to get your

00:31:14password.

00:31:15Let's say you're

00:31:16playing a game of

00:31:17capture the flag, and

00:31:19the other team manages

00:31:20to break into your

00:31:21fort and steal your

00:31:22flag.

00:31:23They now know exactly

00:31:25where your fort is and

00:31:26how to get in.

00:31:28That's basically what

00:31:29hackers do in data

00:31:31breaches.

00:31:32They break into a

00:31:34company's fort, their

00:31:35database, and steal all

00:31:37the sensitive information

00:31:38they can find, like your

00:31:40passwords, credit card

00:31:41details, and even your

00:31:43social security number.

00:31:46Then, they sell this

00:31:48information to other

00:31:49bad guys on the dark

00:31:50net, who can use it to

00:31:51pretend to be you and

00:31:53steal your money or even

00:31:54your identity.

00:31:55Stay up to date on news

00:31:57of data breaches and

00:31:59change your passwords

00:32:00immediately if one of

00:32:01your accounts was

00:32:02affected.

00:32:03And if you receive an

00:32:04email about a data

00:32:05breach, don't respond to

00:32:07it.

00:32:07Instead, visit the

00:32:08company's website or

00:32:10call their official

00:32:11customer support number

00:32:12to verify the

00:32:13situation.

00:32:16Phishing is when these

00:32:17thieves send you fake

00:32:19emails that look like

00:32:20they're from important

00:32:21people or companies, like

00:32:23the president or your

00:32:25bank.

00:32:25They might even ask you

00:32:27to click on a link that

00:32:28takes you to a fake

00:32:29website that looks real,

00:32:31but it's actually a

00:32:32trap.

00:32:34If you fall for their

00:32:36tricks and give them

00:32:37your password or personal

00:32:38information, they can use

00:32:40it to sneak into your

00:32:41computer and steal more

00:32:42stuff.

00:32:43Yikes!

00:32:44Don't reply to strange

00:32:45messages or click on weird

00:32:47links.

00:32:48If you're not sure if an

00:32:49email is real or fake, do

00:32:51some detective work and

00:32:53contact the sender directly

00:32:54through their official

00:32:55website.

00:32:55And remember, never, ever

00:32:58give away your personal

00:32:59information to anyone, even

00:33:01if they claim to be your

00:33:02long-lost cousin or a

00:33:04famous celebrity.

00:33:07Have you ever gotten an

00:33:09email that says something

00:33:10like, reset your password

00:33:12now, but you don't

00:33:13remember asking for it?

00:33:16Yep, hackers once again.

00:33:18They send you fake emails

00:33:20that look like they're from

00:33:21a website you use, like

00:33:23Facebook or Amazon.

00:33:25They'll say something like,

00:33:27Your account has been

00:33:28hacked.

00:33:28Reset your password now to

00:33:30be safe.

00:33:32But if you click on the

00:33:34link they provide, it'll

00:33:36take you to a fake website

00:33:37that looks real, and

00:33:39hackers will be able to see

00:33:40any information you put in

00:33:42there.

00:33:42So, if something in your

00:33:44email seems weird, it's

00:33:46probably a scam.

00:33:47Check for signs of fraud,

00:33:49like spelling mistakes or

00:33:51strange designs.

00:33:52And always make sure to

00:33:54check the sender's email

00:33:55address to see if it matches

00:33:57the website they're claiming

00:33:58to be from.

00:34:00If hackers manage to get

00:34:02your passwords, they can

00:34:04cause serious issues to

00:34:05your reputation, finances,

00:34:07and other things related

00:34:08to your online identity.

00:34:10That means access to your

00:34:12social media accounts, email,

00:34:14personal identifiable

00:34:15information, and more.

00:34:19Let's play detective and spot

00:34:21the signs of a hacked

00:34:22password.

00:34:23First, if your password

00:34:25suddenly stops working, it

00:34:27might mean a hacker has

00:34:28changed it.

00:34:29So if you're locked out of

00:34:31your account for no reason,

00:34:32it's time to investigate.

00:34:36Next, if your computer starts

00:34:38acting slow and sluggish, it

00:34:41could be a sign that it's been

00:34:42infected with password-stealing

00:34:44malware.

00:34:44Another thing to watch out for

00:34:47is finding your personal

00:34:48information on the dark web.

00:34:50That's like the sketchy black

00:34:52market of the internet where

00:34:53hackers sell stolen data.

00:34:55If you see your info for sale

00:34:57there, it's time to take action.

00:35:01Have you ever heard of

00:35:03ransomware?

00:35:04It's a type of malware that

00:35:06locks you out of your own

00:35:07computer and demands money if you

00:35:09want to regain control.

00:35:10Yikes!

00:35:12In Costa Rica, hackers even

00:35:14attacked local authorities with

00:35:16this nasty stuff.

00:35:19Last but not least, if your

00:35:21friends or family start receiving

00:35:23strange messages from you online,

00:35:25it's a red flag that someone else

00:35:27might be using your accounts.

00:35:29So if your BFF gets a message from

00:35:32you about buying a Nigerian

00:35:34prince's yacht, it's probably time

00:35:36to change your passwords, ASAP.

00:35:44You must have noticed those lines on

00:35:47some kinds of chips.

00:35:48For one thing, they help with the

00:35:50distribution of spices and seasonings.

00:35:52In other words, all those substances

00:35:54that make your chips taste like cheese

00:35:56are mostly stored inside the lines.

00:36:00Plus, the lines make chips crunchier.

00:36:04Some cars have a tiny coffee cup sign

00:36:07on their dashboard.

00:36:08It's the vehicle's anti-drowsiness

00:36:11mechanism.

00:36:12There are manufacturers that equip

00:36:14their cars with a drowsiness

00:36:16detection system.

00:36:17It analyzes the speed, wheel angle,

00:36:20and lane deviations to figure out if

00:36:23it's time for the driver to take a

00:36:24break.

00:36:25If it is, the vehicle makes several

00:36:27audio signals and the coffee cup sign

00:36:30starts to flash.

00:36:33Some plastic milk containers have

00:36:35dents on their sides.

00:36:37These dents serve several purposes.

00:36:40For one thing, when milk spoils,

00:36:43this process usually causes swelling

00:36:45and high pressure buildup inside the

00:36:47container.

00:36:48That's when the dent comes in handy.

00:36:50It pops out and doesn't let the jug

00:36:52blow up.

00:36:54Plus, if you decide to freeze the milk,

00:36:57it will expand like any other liquid.

00:36:59And then again, the indentation will pop

00:37:02out and prevent the container from

00:37:04breaking inside your freezer.

00:37:07You might have wondered why jerry cans have

00:37:10three handles.

00:37:11It's a clever designer move.

00:37:13This way, if you carry the container alone,

00:37:17you can use only the central handle to

00:37:19distribute the weight evenly.

00:37:21But if your friend wants to help you out,

00:37:24each of you can grab the side handle.

00:37:28The first jeans had a problem.

00:37:30Workers and miners, who were the original

00:37:32jeans wearers, put too much pressure on the

00:37:35poor piece of clothing.

00:37:36As a result, the seams couldn't withstand the

00:37:39stress and tore.

00:37:42Tiny metal studs were invented to prevent this

00:37:45from happening.

00:37:47Sticky notes come off relatively easily because

00:37:50their adhesive is spread out across the paper

00:37:52unevenly, in small blobs.

00:37:55And only some of these blobs touch the surface of

00:37:58whatever you've stuck the note on.

00:38:00That's why when you unstick a post-it and attach it to

00:38:03something else, it still works until all the glue gets

00:38:07used or covered with dirt.

00:38:10Soda bottles are always filled in such a way that

00:38:13there's some space between the liquid and the cap.

00:38:17That's because soda contains carbon dioxide.

00:38:20It's a gas that can expand once a bottle is heated.

00:38:24If there's no gap in the bottle, it can break because of

00:38:27the pressure building inside.

00:38:30Also, when you open your drink, the gases go out in the

00:38:33form of bubbles, and the drink is likely to overflow.

00:38:36Oh, the gap helps with this problem, too.

00:38:41Dental floss is super useful for your teeth, but it might be

00:38:45rather hard to operate.

00:38:46It regularly slips out of your fingers and tangles.

00:38:50To avoid these problems, tear off a piece of dental floss and

00:38:55tie its two ends together.

00:38:57It'll be much easier to use and won't hurt your fingers.

00:39:01Now, about those horizontal lines on plastic bottles.

00:39:06They help hold bottles up.

00:39:08Some bottles are produced from soft plastic.

00:39:12Without the lines, they wouldn't keep their shape.

00:39:15Instead, they would twist easily or even break.

00:39:20The soft, round part under a soda bottle cap keeps the

00:39:24carbonation from escaping.

00:39:26Without it, your pop would go flat in no time, probably even

00:39:31before you buy it.

00:39:33If you don't have anywhere to put a toothpick after using it,

00:39:37break off its flat end at the first groove and place it on the

00:39:41table.

00:39:41Now, you can balance the used portion of your toothpick on the

00:39:45groove part so that it doesn't have to touch the table.

00:39:49You can also make a makeshift stand for disposable chopsticks.

00:39:54They have a sort of lump on one side.

00:39:57Break that lump off before you split the pair.

00:40:00Now, when you want to take a sushi break, just place the stick on

00:40:04this stand.

00:40:07Donuts are shaped like rings because, otherwise, they might get

00:40:11overdone at the edges, but uncooked and gooey inside.

00:40:16With a hole in the center, both the outside and the inside get

00:40:20ready at the same time.

00:40:23Ever notice that layer of clear fluid in gel pens?

00:40:27It's called the ink follower or stopper fluid.

00:40:31The gel in such pens contains pigment particles dissolved in a

00:40:35polymer solution.

00:40:37The gel should be thick enough to keep the pigment particles

00:40:40suspended, but also thin enough to flow first onto the ball and

00:40:44then the paper.

00:40:47The main task of the stopper fluid is to be a barrier to prevent

00:40:51the gel from evaporating or leaking out.

00:40:54Without this transparent fluid, your gel pen wouldn't function.

00:40:58The fluid always stays in one position and doesn't get dissolved

00:41:02with the gel.

00:41:03Neither does it move backward or flow out of the pen.

00:41:08Some button-down shirts have a button hidden on the back of the

00:41:11collar.

00:41:13Its main purpose is to prevent the tie from sticking out from under

00:41:17the collar.

00:41:19As for that locker loop on the back, you can use it to hang the

00:41:24shirt on a hook to avoid wrinkling it.

00:41:28Outer rings and zipper sliders, especially when two sliders are used

00:41:32together, are added so that you can connect them with a lock and keep

00:41:36sticky fingers away.

00:41:39Most ambulance cars have this word printed on the front of the vehicle.

00:41:43That's the word ambulance backward.

00:41:47It's written in reverse so that the driver in front of the ambulance can see the word

00:41:52properly in their rearview mirror.

00:41:54Then they can move out of the way and let the ambulance pass.

00:42:00Escalator brushes serve an important safety purpose.

00:42:03You might have heard that most accidents happen after people get their bags or clothes stuck in

00:42:09escalators because they stand too close to the sides.

00:42:12But when there are nylon brushes on both sides, you can't but keep your feet away from the

00:42:18escalator's skirt panels.

00:42:19The result?

00:42:20No accidents.

00:42:22The side holes in sneakers are for laces.

00:42:27Since sneakers were originally invented for basketball players, this interesting design allowed them to

00:42:33accommodate any player's foot.

00:42:35They just needed to lace their sneakers in the most comfortable way for them.

00:42:40The holes in the bottoms of your earphones allow air to circulate up and through the speakers.

00:42:47It helps to increase low frequencies, making the bass sound deeper.

00:42:52The quality of the sound also becomes much better.

00:42:56Ever been stranded with a cup of applesauce but no spoon at hand?

00:43:01But each snack pack already has a built-in spoon.

00:43:05Several twists of the foil lid and… here you go!

00:43:11Diamond slits on backpacks were originally placed only on traveler bags.

00:43:16Their purpose was to carry robes.

00:43:19These days, you can find such slits on almost every backpack.

00:43:23Why not use them to carry a bottle of water, an umbrella, or a pair of sneakers?

00:43:30Highlighters are filled with a special semi-transparent fluorescent ink.

00:43:34That can glow in dim light.

00:43:37Yellow and light green hues are the most popular.

00:43:40Because they don't prevent you from seeing the text after black and white photocopying.

00:43:46Photocopiers perceive yellow and light green marks as almost non-existent and don't print them.

00:43:53A stop sign has an octagonal shape to help drivers recognize it easily.

00:43:58Even if they see it from the back.

00:44:00When the signs weren't reflective yet, this shape prevented drivers from confusing the stop sign with any other night.

00:44:09The number 57 on a Heinz ketchup bottle has nothing to do with the product label.

00:44:14The truth is that the place with the numbers is the very sweet spot you should tap to get the

00:44:21ketchup flowing.

00:44:22So, stop hitting the bottom of your sauce bottle and hit 57.

00:44:28Lots of private houses have triangular-shaped roofs because this allows rain, snow, and fallen leaves to slide off the

00:44:36slope.

00:44:38If all this stuff piled up on top of your house, one day, your roof would collapse.

00:44:45Airplane windows have rounded edges, and that's a crucial safety measure.

00:44:49It prevents aircraft accidents.

00:44:52Weak spots are usually situated in the corners.

00:44:56If airplane windows were square or rectangular, each of them would have four potential weak spots.

00:45:02Under pressure, they would collapse.

00:45:07Here's how you can protect your bank card from potential fraudsters.

00:45:10Use a marker and cover the last four digits.

00:45:13You can also use a sticker that's easy to remove and place it over the security code.

00:45:18Have you had a houseguest that didn't use a coaster?

00:45:21Get a hair dryer and hold it a couple of inches away from the stain.

00:45:25Blow it on medium heat for a couple of minutes to evaporate the watermark.

00:45:28If a faded ring remains, mix equal amounts of vinegar and olive oil in a bowl.

00:45:34Wipe it onto the marked area and rub it in until the stain disappears.

00:45:37Then wipe it off.

00:45:39Don't waste time scrubbing the burnt stains off the bottom of a pan.

00:45:42Instead, fill it with water and add three tablespoons of salt.

00:45:46Let it sit overnight as the salt dissolves the burnt marks.

00:45:50And in the morning, pour the water out of the pan.

00:45:52This way, it will be much easier to scrub all that grease off.

00:45:56Picture this.

00:45:57You're on vacation and your shirt has become all crinkled inside the luggage.

00:46:01You need it tonight, but the hotel doesn't have an iron.

00:46:04Don't panic.

00:46:05Hang the shirt up in the bathroom.

00:46:07And while you relax in a hot shower, the heat and moisture will unwrinkle your shirt.

00:46:11It won't be perfect, but it will get much better without any effort.

00:46:15The football is on and it turns out you've run out of standard batteries.

00:46:19You can use a smaller battery instead that easily fits inside.

00:46:23Now take some aluminum foil and crunch it up.

00:46:26Fit it into the gap on the negative or flat end of the battery.

00:46:30All done.

00:46:30You can turn on the TV now.

00:46:33Once your flip-flops crack and the plug easily slips out of the hole,

00:46:36it's normally a sign that you need a new pair.

00:46:39But there's a way to extend their mileage.

00:46:41Push the plug back through the hole.

00:46:43Then take a bread clip and attach it to the end.

00:46:46The clip will provide enough support for the plug to remain in place.

00:46:50You've received a package and the receipt is taped on.

00:46:53You've managed to detach it from the box.

00:46:55But how to separate the tape without ripping the paper?

00:46:58Hold both ends of the tape apart and by pulling it slowly,

00:47:02the tape stretches and separates itself from the paper without tearing it apart.

00:47:08Zip-lock bags are perfect to keep things dry.

00:47:11But it would be great if they were larger.

00:47:13Take two and turn one of them inside out.

00:47:16They can now connect and work as one large bag.

00:47:19Big enough to protect a keyboard.

00:47:21There's no need to carry your keys in your hand when you go for a job.

00:47:25Instead, put them inside your pocket,

00:47:27take a rubber band,

00:47:28then tie it around the pocket from the inside.

00:47:31This stops the keys from falling out.

00:47:34You've broken your key in the door.

00:47:36It's stuck.

00:47:37Great!

00:47:38Arranging for a locksmith could cost up to $100.

00:47:41But for a cheaper and quicker option,

00:47:43try using a hot glue stick.

00:47:45Heat the end with a lighter.

00:47:46And once it's warm enough to melt,

00:47:48push the glue into the keyhole.

00:47:50The melted glue will enter the available space covering part of the key.

00:47:55Once it cools,

00:47:56it compresses and gains a strong hold of the key's end.

00:47:59Now, just pull it out.

00:48:02If you need to siphon liquid through a hose

00:48:04and want to avoid using your mouth,

00:48:06put one end in the liquid

00:48:07and hold the other upwards with your thumb closing the top.

00:48:10Now shake up and down.

00:48:12This jiggle motion pushes liquid upwards,

00:48:14a little each time.

00:48:16And once it reaches the top,

00:48:18lower the exit point

00:48:19and let gravity do the rest.

00:48:21You've left your keys locked inside the car.

00:48:24It's an older model with a roll-down window.

00:48:26You could get the coat hanger

00:48:27and begin the long process of finding the lock.

00:48:30Or use duct tape.

00:48:32Make about 20 2-foot-long strands.

00:48:34Stick them onto the window,

00:48:36allowing enough room for the tape to grab onto at the bottom.

00:48:39Then, with a friend,

00:48:40take the ends of the tape,

00:48:41holding them together,

00:48:43and pull downwards.

00:48:44The force will allow the window to lower enough

00:48:46that you can unlock the door.

00:48:49While drilling long screws into hardwood,

00:48:51your old drill might not have enough power,

00:48:53leaving them only halfway in.

00:48:56Before the drill gives up,

00:48:57get a block of wax

00:48:58and scrape the edges of the screws with it.

00:49:00The wax works like a lubricant,

00:49:02melting as it gets warm

00:49:03and providing easy entry for the screw.

00:49:07You're out camping,

00:49:08but you didn't bring anything to light the barbecue.

00:49:10Take a small plastic bag that won't leak,

00:49:13fill it up with water,

00:49:14and close it tight,

00:49:15making a round bubble.

00:49:17Hold it over where you want

00:49:18to catch the light from the sun.

00:49:20The bag of water will work like a magnifying glass,

00:49:23starting up the barbecue,

00:49:24just as long as it's a sunny day.

00:49:27Missing a corkscrew or a cork breaking halfway?

00:49:30By using a stove lighter,

00:49:31heat the top of the bottle.

00:49:32The heat slightly expands the glass,

00:49:35and this forces the cork out the top.

00:49:38You've superglued your fingers again.

00:49:40Take some salt

00:49:41and pour it on top of your stuck fingers.

00:49:43Put your fingers into the water

00:49:45and slowly rub.

00:49:46The mixture will dissolve the glue

00:49:48and release you in no time.

00:49:50While hanging up a painting,

00:49:52it can be impossible to find that stubborn nail.

00:49:54Place a fork upside down

00:49:56and insert it so the nail

00:49:57is in between the middle fork teeth.

00:50:00The fork has provided a long arm

00:50:02that's separated from the wall,

00:50:04making it easier to slip the string

00:50:05of the painting over the nail.

00:50:07Once it's perfectly balanced,

00:50:09simply remove the fork.

00:50:13You need to put a cake into a container,

00:50:15but taking it out again later

00:50:17by lifting it up from the inside

00:50:18might ruin the cake.

00:50:20Put the lid upside down

00:50:21and place the cake on the lid.

00:50:23The base of the container

00:50:24is now the lid,

00:50:26making it much easier to access

00:50:28slice by slice.

00:50:30Pour out water more efficiently

00:50:32from large jugs and bottles

00:50:34by swirling.

00:50:35This will make the liquid inside spin,

00:50:37creating a vortex.

00:50:38The vortex allows for the air

00:50:40to flow back into the bottle

00:50:42as the water pours out,

00:50:43much faster than the glugging alternative.

00:50:47There's an easier and less messy way

00:50:50to remove eggshells from a boiled egg.

00:50:52Once fully boiled,

00:50:53crack the shell on both ends

00:50:55by tapping them.

00:50:56On one end,

00:50:57pinch off the shell.

00:50:58Use the opened end

00:50:59to blow with your mouth.

00:51:00The force of air

00:51:01will push the flesh

00:51:02and expand the eggshell,

00:51:04forcing out the egg undamaged.

00:51:08When the hinges of your laptop break,

00:51:10repairing them can cost up to $300.

00:51:13A far cheaper fix

00:51:14is to buy a picture frame

00:51:16and tape it to the back of the screen.

00:51:19You've dropped a small piece of jewelry

00:51:20on the floor,

00:51:21seemingly impossible to find.

00:51:24Take a stocking

00:51:25and place it over the end

00:51:26of the vacuum hose.

00:51:27Give the area a good vacuum

00:51:28and check the end periodically.

00:51:30You will eventually find it

00:51:32sitting at the end.

00:51:33You've drilled a hole in the wall,

00:51:35but the drill hole

00:51:36is now too wide.

00:51:37Remove the screw

00:51:38and find an object

00:51:39that is slightly shorter

00:51:41and thinner.

00:51:41Pieces of plastic,

00:51:43small wires,

00:51:44paper clips,

00:51:44or even toothpicks

00:51:45are perfect.

00:51:46Place whichever item

00:51:48you find inside the hole.

00:51:49It's filled the gap enough

00:51:50so the screw

00:51:51will now re-enter securely.

00:51:53Taking the trash out

00:51:54can put you

00:51:55in a gross scenario

00:51:56of getting bin juice on you.

00:51:58A great way to avoid this

00:51:59is by placing old papers

00:52:01at the bottom of the bag.

00:52:02Now,

00:52:03not only does it absorb

00:52:04all the liquids

00:52:05from the food

00:52:06and other sources,

00:52:07but also helps prevent

00:52:08bad smells

00:52:09from forming within a bin.

00:52:10Nobody likes mosquitoes

00:52:12and pesticides are pricey.

00:52:14A cheap alternative

00:52:15is to take a plastic bottle

00:52:17and cut the top part off

00:52:19from the bottom of the funnel.

00:52:20After removing it,

00:52:22turn it upside down

00:52:23and put it inside the bottle.

00:52:24Mix two cups of warm water

00:52:26with two tablespoons of sugar.

00:52:28The mosquitoes

00:52:29will be attracted

00:52:30to the formula inside

00:52:31and become trapped.

00:52:33Now just sit back

00:52:34and relax

00:52:34without getting bitten.

00:52:38Pockets are usually

00:52:39on the left side

00:52:40of shirts

00:52:40because most people

00:52:41are right-handed.

00:52:42Is this a myth

00:52:43or a fact?

00:52:45This is actually true.

00:52:47Many products

00:52:47favor the righties.

00:52:49Left-handed people

00:52:49will relate to this

00:52:50on so many levels.

00:52:52Let's say,

00:52:53public transport.

00:52:54Have you ever noticed

00:52:55that the scanner

00:52:56at stations

00:52:57is typically

00:52:57on the right side?

00:52:59Household equipment

00:53:00and devices

00:53:01are one more example.

00:53:02Scissors,

00:53:03tweezers,

00:53:03bottle openers,

00:53:04and many other kitchen

00:53:05and household appliances

00:53:06are designed

00:53:07with right-handed people

00:53:09in mind.

00:53:10The same goes

00:53:11for shirt pockets.

00:53:12While some people

00:53:13use both hands equally

00:53:14and others change

00:53:15their hand preference

00:53:16between tasks,

00:53:17overall,

00:53:18most people

00:53:18are right-handed.

00:53:20A study has revealed

00:53:21that 75%

00:53:23to 90%

00:53:24of the world's population

00:53:25are right-handed

00:53:26and 10%

00:53:27are left-handed.

00:53:28This means

00:53:29it's more convenient

00:53:30for most people

00:53:30to have pockets

00:53:31on the left side

00:53:32than on the right side

00:53:33of their garments.

00:53:35Try it out

00:53:35for yourself.

00:53:36Your elbow

00:53:37kind of folds

00:53:37when you try

00:53:38to reach into the pocket

00:53:39on the right side.

00:53:41Whereas on the left side,

00:53:42your elbow

00:53:43makes an arc shape,

00:53:44which makes it easier

00:53:45to put things

00:53:45inside the pocket

00:53:46and take them out.

00:53:48Eating more protein

00:53:50leads to having

00:53:50bigger muscles.

00:53:51What do you think

00:53:52about this,

00:53:53bodybuilders?

00:53:54Myth or fact?

00:53:56This is a myth.

00:53:57It's true

00:53:58that eating protein

00:53:59is essential

00:54:00for building bigger muscles.

00:54:01I mean,

00:54:02proteins are

00:54:02building blocks

00:54:03of your body.

00:54:04And yet,

00:54:05eating more than you need

00:54:06is unnecessary.

00:54:08Everyone should drink

00:54:09eight glasses of water a day.

00:54:11Do you think

00:54:11this is a myth

00:54:12or a fact?

00:54:14This is a myth,

00:54:16so don't blame yourself

00:54:17for drinking less water

00:54:18than recommended.

00:54:19Eight glasses

00:54:20are not a magic number.

00:54:22Hydration needs

00:54:23differ from one person

00:54:24to another.

00:54:25How much water

00:54:26you should drink

00:54:27every day

00:54:27depends on your activity

00:54:29and exercise level.

00:54:30The temperature

00:54:31of the place

00:54:31where you live

00:54:32affects this number too.

00:54:33If you live

00:54:34in a hot area,

00:54:35you sweat more

00:54:36and need to drink

00:54:36more water.

00:54:37Soup,

00:54:38coffee,

00:54:39tea,

00:54:39fruits,

00:54:40and other things

00:54:41you eat daily

00:54:42also contain water.

00:54:44Carrots are high

00:54:46in sugar,

00:54:46so you should

00:54:47avoid eating them.

00:54:48If this is true,

00:54:49we should warn bunnies.

00:54:50Any guesses,

00:54:52fact,

00:54:52or myth?

00:54:53It's a myth.

00:54:55Carrots are about

00:54:5585% water.

00:54:57One pound of cooked carrots

00:54:59only contains

00:54:593 teaspoons of sugar.

00:55:01Compared to the amount

00:55:02of sugar in desserts,

00:55:03this is nothing.

00:55:05Plus,

00:55:05carrots are high

00:55:06in phytochemicals

00:55:08and eating them

00:55:09can help lower

00:55:09blood sugar.

00:55:11Medieval people

00:55:12believed in flat earth.

00:55:14Is this a myth

00:55:15or a fact?

00:55:16Obviously,

00:55:17flat earth is a myth.

00:55:19But so is the history

00:55:20built around this myth.

00:55:21You can't say that

00:55:22at those times.

00:55:24The whole world

00:55:24was skeptical

00:55:25about earth's

00:55:26spherical shape.

00:55:27Even everyday

00:55:28visible things

00:55:29proved that.

00:55:30For example,

00:55:31medieval people

00:55:31could see that

00:55:32the twilight glow

00:55:33during sunrise

00:55:34and sunset

00:55:35formed an arc

00:55:36over the horizon.

00:55:38Vikings wore

00:55:40horned helmets.

00:55:41Is this a myth

00:55:42or fact?

00:55:43The well-known image

00:55:45of a Viking warrior

00:55:46is almost always

00:55:47completed with

00:55:48a horned helmet.

00:55:49But in reality,

00:55:50there were no horns.

00:55:52There's no evidence

00:55:53that Viking helmets

00:55:54were horned.

00:55:57Detox juices

00:55:57cleanse your body.

00:55:58Is this a fact

00:55:59or myth?

00:56:01It's a myth.

00:56:03Detoxification

00:56:03doesn't work that way.

00:56:05Your internal organs

00:56:05are responsible

00:56:06for the process

00:56:07of cleansing

00:56:08the spleen,

00:56:09liver,

00:56:09kidneys,

00:56:10especially the liver.

00:56:12Your body

00:56:13is always in a natural

00:56:14state of cleansing itself.

00:56:16A person doesn't need

00:56:17to drink juices

00:56:18for detoxification.

00:56:21Nuts are junk food.

00:56:22Any thoughts?

00:56:23Myth or fact?

00:56:26You're right.

00:56:27This is a myth.

00:56:29Nuts are full

00:56:30of healthy fats.

00:56:31They're good

00:56:32for your heart

00:56:32and other organs.

00:56:34The average American

00:56:36throws away

00:56:37about 82 pounds

00:56:38of textile waste

00:56:39per year.

00:56:40Is this a fact

00:56:41or myth?

00:56:43Fact!

00:56:44Imagine all that waste.

00:56:46When someone throws

00:56:47their clothes away,

00:56:47they don't disappear

00:56:48into thin air.

00:56:49These items

00:56:50most likely reach

00:56:51landfills

00:56:52as their final destination.

00:56:54Donating clothes

00:56:55and selling them

00:56:56in second-hand stores

00:56:57are a much better option.

00:56:59Now,

00:57:00you've probably heard

00:57:01about life-saving

00:57:02laundry tricks

00:57:03that are said

00:57:03to make your clothes

00:57:04super clean

00:57:05and as good as they were

00:57:06on day one.

00:57:07What if those laundry tips

00:57:09are actually myths?

00:57:11I got three of them

00:57:12lined up for you.

00:57:14Shirts should be buttoned

00:57:15when you put them

00:57:16in the laundry.

00:57:16Is it true?

00:57:17Or not?

00:57:19This is a myth.

00:57:20You'd better keep

00:57:21zippers closed

00:57:21to keep their teeth

00:57:22from catching the fabric

00:57:23of other clothes.

00:57:25But fastening the buttons

00:57:26of a shirt

00:57:26can expand the button net

00:57:28and the button hole.

00:57:29In the long term,

00:57:30buttons will start

00:57:31slipping out of place.

00:57:34Washing clothes

00:57:35in hot water

00:57:35is the most effective

00:57:36way to clean them.

00:57:37Is this a myth

00:57:39or a fact?

00:57:40That's another laundry myth.

00:57:42You want to rid

00:57:43your clothes of germs,

00:57:44yet hot water alone

00:57:46won't be enough for this.

00:57:47Nowadays,

00:57:48many detergents

00:57:49can clean clothes

00:57:50in cold or warm water.

00:57:53You should remove stains

00:57:54from the face of the fabric.

00:57:56Is it true?

00:57:58Most people apply water

00:57:59and soap to the stain,

00:58:01starting from the front side

00:58:02of the fabric,

00:58:03but that's not the best option.

00:58:05A much better way

00:58:06is to start from the back.

00:58:07The stain can go deeper

00:58:09if you treat it

00:58:09from the front.

00:58:10Try to make the stain

00:58:11move up to the surface

00:58:13rather than push it inside.

00:58:16Listening to music

00:58:17is an effective tool

00:58:18for learning languages.

00:58:20Is it a myth or fact?

00:58:22It's a fact!

00:58:24Scientists say

00:58:25listening to a song

00:58:26and humming along

00:58:27can help you learn a language.

00:58:28Most people struggle

00:58:30to learn grammar,

00:58:31yet in our daily lives,

00:58:32we don't always follow grammar rules.

00:58:35Songs can help you

00:58:36pick up informal expressions.

00:58:39Scientists have also concluded

00:58:40that music

00:58:41can help you remember new words

00:58:43and add them to your vocabulary.

00:58:45Let me give you an example.

00:58:46It's from your first year at school.

00:58:48Yep, the alphabet song.

00:58:51Are you a morning person

00:58:53or a night owl?

00:58:54Either way,

00:58:55you might want to know

00:58:56these facts and myths

00:58:57about sleep.

00:58:59The longest someone went

00:59:01without sleep was 11 days.

00:59:03Do you think this is possible?

00:59:05Or is it an urban

00:59:06legend?

00:59:07This is a fact!

00:59:09Randy Gardner

00:59:10set the record

00:59:11for the longest amount of time

00:59:12a person went without sleep.

00:59:14It was an experiment

00:59:15carried out

00:59:15by Stanford sleep researcher

00:59:17Dr. William C. Demand.

00:59:19The doctor recorded

00:59:21and monitored

00:59:21Randy Gardner's sleep activity.

00:59:23Gardner managed to stay awake

00:59:25for 11 days and 25 minutes.

00:59:29Your body eventually gets used

00:59:31to getting less sleep.

00:59:32Myth or fact?

00:59:34It's a myth.

00:59:35There are many studies

00:59:37proving that your body

00:59:38and especially your brain

00:59:39can't get used

00:59:40to sleeping less.

00:59:42Have you noticed

00:59:42that after a few nights

00:59:43of insufficient sleep

00:59:44you begin to feel groggier

00:59:46during the day?

00:59:47That's your body

00:59:48trying to adjust

00:59:49to not getting enough rest.

00:59:50Long-term sleep deprivation

00:59:52affects your daytime performance,

00:59:54focus,

00:59:54and decision-making.

00:59:57Many grown-ups need 5 or fewer hours of sleep.

01:00:00Can it be true?

01:00:02Well, this one's easy.

01:00:04It's a myth.

01:00:05Experts from the National Sleep Foundation

01:00:07recommend that the average adult

01:00:09sleeps 7 to 9 hours per night.

01:00:11Some people have a genetic mutation

01:00:14thanks to which they wake up refreshed

01:00:16after a short night's sleep,

01:00:17but such people are an exception.

01:00:19One in 4 million.

01:00:22The ability to fall asleep in any place

01:00:24and at any time

01:00:26means you're a good sleeper.

01:00:27What do you think?

01:00:29Myth or fact?

01:00:31It's a myth.

01:00:32A good sleeper gets a proper amount of sleep

01:00:34and has a regular sleep schedule.

01:00:37Cats spend two-thirds of their life asleep.

01:00:40Do you believe that?

01:00:42This will probably come as no surprise.

01:00:45It's a fact.

01:00:46How many of the facts and myths

01:00:48did you guess correctly?

01:00:51Did you know that you can actually inflate a balloon

01:00:54without using your lungs?

01:00:55All you need is a plastic bottle,

01:00:58vinegar, baking soda,

01:00:59a funnel,

01:01:00a rubber band,

01:01:02and a balloon, of course.

01:01:04First, pull some baking soda

01:01:06into the balloon using your funnel.

01:01:09And now, pour the vinegar into the bottle.

01:01:12You don't need a lot.

01:01:14Just fill about a third of the bottle.

01:01:16Let's go ahead and put the balloon over the bottle.

01:01:19But don't tip the soda inside the vinegar yet.

01:01:23Secure the balloon with a rubber band.

01:01:25And tip it over to make the soda fall into the vinegar.

01:01:28And now you can step back and enjoy the show.

01:01:32When the baking soda and the vinegar are mixed together,

01:01:35they release CO2 that will inflate the balloon.

01:01:39You can use the inflated balloon to show your friends another trick.

01:01:43Grab a comb and rub it on the surface of the balloon.

01:01:46Now you can bend the water flow in your sink with static electricity

01:01:50using your brand new electrified comb.

01:01:53Just don't try brushing your hair.

01:01:56Can you really pierce a balloon without popping it?

01:01:59The answer is yes.

01:02:02You're going to need a skewer or a long needle,

01:02:05a balloon, petroleum jelly, and some courage.

01:02:08Scratch the balloon with your fingers and make it more flexible.

01:02:11Now, blow steadily into the balloon.

01:02:15Stop before blowing it to the full size.

01:02:17This will make the trick easier to perform.

01:02:20Put some petroleum jelly on the needle.

01:02:22Now, find this darker area near the knot

01:02:25where the balloon is less stretched

01:02:27and just pierce it all the way through the top, like this.

01:02:31Balloons are made up of polymer chains.

01:02:34They're so tiny that they seem invisible to the human eye.

01:02:37This trick works because the polymer chains

01:02:40are less stretched on the neck of the balloon.

01:02:42It was enough room to allow the needle in between the chains

01:02:46without breaking them.

01:02:47But if you try the same technique on the sides of the balloon,

01:02:50it will definitely pop.

01:02:53By the way,

01:02:55hairspray actually helps keep the air in the balloon longer

01:02:58by sealing the surface.

01:02:59But if you apply hairspray on the outside of the balloon

01:03:02and then touch it when it's not yet dry,

01:03:05the balloon will shrivel.

01:03:06Isn't it magic?

01:03:10Beware!

01:03:11Our next trick can make you question gravity.

01:03:14Pour some plain water into a glass bottle.

01:03:17Not much, about a quarter.

01:03:19Put the bottle in the microwave for a minute.

01:03:22Meanwhile, prepare a bowl with colored water

01:03:25to make the trick more visual.

01:03:27Take the bottle out of the microwave,

01:03:29turn it upside down,

01:03:30and pour it into the colored water.

01:03:33The bottle will soon begin to fill with water.

01:03:36Can you guess why?

01:03:38The air expands when it's heated.

01:03:40The bottle and the air began to cool down,

01:03:42and the air contracted,

01:03:44which caused the water to move.

01:03:48Not only wizards can make things disappear.

01:03:51Fill a plastic container or transparent glass

01:03:54with sunflower oil.

01:03:56Dip a glass rod inside the oil.

01:03:59Can you see it now?

01:04:01Oil and glass bend light the same way

01:04:03because they have almost equal refractive indexes.

01:04:07Therefore, it's impossible to see

01:04:09how the wand bends light inside the oil.

01:04:12To make this trick even more epic,

01:04:15pour equal parts of water and oil inside a glass

01:04:18and dip the glass rod inside it.

01:04:21You'll see it in the water,

01:04:22but it will disappear inside the oil.

01:04:26Have you seen this epic instant freezing trick?

01:04:29Here's how you can repeat it at home.

01:04:32Grab a small plastic bottle of clean drinking water.

01:04:35Leave it for about four hours

01:04:37to bring it to room temperature.

01:04:39And now, put it into a freezer

01:04:41and wait for an hour and a half.

01:04:44After that, take it out very carefully.

01:04:47Try not to shake it at all.

01:04:49Now, hit the bottle strongly

01:04:50or shake it and see what happens.

01:04:54Not only is red cabbage rich in fiber and vitamins,

01:04:57but it's also pretty useful

01:04:59for homemade scientific experiments.

01:05:02Boil red cabbage in pure water

01:05:04and wait until the water gets colored.

01:05:07Red cabbage contains a chemical called anthocyanin.

01:05:11It changes color when it's mixed with an acid or a base.

01:05:15That's why if you mix your cabbage with water

01:05:17with different ingredients,

01:05:18you'll get different colors.

01:05:21Bases like soda will make it blue,

01:05:23but acids, on the contrary,

01:05:25will create reddish colors.

01:05:27You can prove it by adding some lemon juice

01:05:29to your cabbage water.

01:05:30The water will become pinkish.

01:05:34And if you add vinegar,

01:05:35you'll get an even more vibrant pink color.

01:05:39If you have a juicer,

01:05:41you can try the same experiment with red cabbage juice.

01:05:44Initially, it will have a more vivid purple color,

01:05:47but under the influence of additional liquids,

01:05:50the color will change.

01:05:52Can you guess which color you'll end up with

01:05:54if you mix cabbage juice with bleach?

01:05:56It's almost transparent,

01:05:58but still has a greenish-yellow tinge.

01:06:02The next trick is very trendy among artists.

01:06:05Here's what you're going to need.

01:06:07Liquid soap, cotton buds, milk, and acrylic paints.

01:06:11You can use food coloring for this tip.

01:06:14Pour a little bit of milk into a wide bowl or a plate.

01:06:17You don't need a lot.

01:06:19Then, put a few drops of paint into the milk.

01:06:22And now dip a cotton bud covered with soap.

01:06:25The patterns will begin to change.

01:06:27That's because the fatty molecules in the milk

01:06:30get attracted to the molecules of soap.

01:06:33When you're satisfied with the pattern,

01:06:35you can put a sheet of paper on top of the milk.

01:06:38And voila, your abstract masterpiece is ready.

01:06:42In fact, this technique is related

01:06:44to an ancient paper marbling called ebrew.

01:06:48Artists created colorful patterns

01:06:50by sprinkling and brushing color pigments

01:06:52on a pan of oily water

01:06:53and then transformed those patterns on paper.

01:06:58Friction helps people walk on the road

01:07:00instead of sliding on it.

01:07:02And it also allows us to perform this cool experiment

01:07:05called floating rice.

01:07:08Fill a small plastic bottle with rice.

01:07:11You can use a funnel to make the task easier.

01:07:13Shake the rice for a while.

01:07:15And now try to push a chopstick or a pencil inside the bottle.

01:07:19If you did everything right,

01:07:21the stick will get stuck in the rice.

01:07:23You can also try using different types of grains

01:07:26and see what happens.

01:07:28Have you ever tried to put an ice cube into oil?

01:07:32Well, you can try today.

01:07:33It will create these cute little drops

01:07:35that will fall into the bottom of the glass

01:07:37because they're heavier than oil.

01:07:42Here's an easy way to stick an ice cube to a string

01:07:45without any glue.

01:07:46Place an ice cube in water.

01:07:48Put a piece of string on top

01:07:50and sprinkle it with salt.

01:07:52You don't need much,

01:07:53otherwise the ice will dissolve.

01:07:55A pinch is enough.

01:07:57Wait for one minute

01:07:59and then gently pull the string.

01:08:01And there you go.

01:08:02The ice has stuck to the string.

01:08:06For this experiment,

01:08:08you're going to need an empty, clean soda can.

01:08:10Turn on the kettle

01:08:11and wait until it begins to boil.

01:08:14Carefully hold the can over the kettle

01:08:16using kitchen tongs.

01:08:18It will help fill it with hot steam.

01:08:20When the can is full of steam,

01:08:22give it an ice bath.

01:08:24You can put it into a bowl with cold water and ice cubes.

01:08:28The can should wrinkle up right away.

01:08:30That's because the volume inside the can decreases,

01:08:34reducing its pressure

01:08:35and allowing the external pressure to crush the can.

01:08:39The next trick is also about air pressure.

01:08:42You're going to need a glass bottle,

01:08:44a small piece of paper,

01:08:45a lighter and a peeled, boiled egg.

01:08:48The diameter of the bottleneck

01:08:50should be less than the width of the egg.
