00:01What's hiding inside Coca-Cola cans and regular household batteries?
00:05Why do magnets affect breakfast cereals?
00:08Do crosswalk buttons actually work or are they just useless decorations?
00:14What does that USB symbol really mean?
00:17I'm not sure I know the answers to these and similar questions,
00:21but I'm eager to learn the truth together with you.
00:24Let's find it out.
00:26Coca-Cola cans have a secret few people know about.
00:30Here's a Coke can.
00:31Let's submerge it in a highly corrosive alkaline solution.
00:35The aluminum dissolves due to a process known as hydrolysis,
00:39and we can see a plastic liner inside the can.
00:42It's made from a polymer or epoxy resin
00:45and serves as some kind of a protective barrier
00:48between the aluminum walls of the can and the rather acidic soda.
00:53Despite a popular myth, household batteries don't actually contain liquid,
00:58and if you accidentally cut them open, no toxic liquid will spill.
01:02Most of them are dry cell batteries which are made of electrochemical cells.
01:06Those convert chemical energy into electrical energy.
01:10Larger batteries often house numerous small cells within them too.
01:14Even Tesla vehicle batteries consist of multiple small cells.
01:18When combined, they easily provide the necessary voltage.
01:24Most toothbrushes have differently colored bristles,
01:27but they aren't just pleasing to the eye.
01:29Those bristles, often blue, have a functional purpose.
01:32They're called toothbrush indicators,
01:34and their colors fade as you use the brush.
01:37The American Dental Association recommends changing your toothbrush
01:40at least four times a year.
01:43And by getting paler,
01:44these bristles help you figure out when it's time to replace your toothbrush.
01:49You'll probably agree that there's no better snack than a pack of chips.
01:53Some are flat, others have ridges.
01:55Is it just aesthetics?
01:57Not really.
01:58The main purpose of those lines on some kinds of chips
02:01is to help with the distribution of spices and seasonings.
02:04In other words,
02:05all those substances that make your chips taste like cheese
02:08are mostly stored inside the lines.
02:11Plus, the lines make chips crunchier.
02:15Now, this one might be a surprise,
02:17but some breakfast cereals are magnetic.
02:19That's because they're often fortified with iron
02:22in the form of a fine powder.
02:24Due to the added iron,
02:26cereal flakes get attracted to magnets.
02:28All this may sound kind of alarming,
02:30but in reality,
02:31the iron content in the flakes is minimal
02:33and doesn't pose any threat to your health.
02:37That clear fluid in gel pens
02:38is called the ink follower or stopper fluid.
02:41The gel in such pens contains pigment particles
02:44dissolved in a polymer solution.
02:47The main task of the stopper fluid
02:49is to be a barrier
02:50to prevent the gel from evaporating or leaking out.
02:53Without this transparent fluid,
02:55your gel pen wouldn't function.
02:58The fluid always stays in one position
03:00and doesn't get dissolved with the gel.
03:02Neither does it move backwards
03:04or flow out of the pen.
03:07Many pedestrian crosswalk buttons,
03:09namely in New York,
03:11are placebo buttons.
03:12They do literally nothing when you press them.
03:15Originally, they were functional
03:17after being introduced in 1964,
03:19but today,
03:20most of them don't affect traffic lights,
03:22which are programmed
03:22based on the real needs of the traffic flow.
03:26Why do such buttons even exist then?
03:28It's a simple psychological trick,
03:30providing you with an illusion of control.
03:34You might have noticed
03:35that movie theater seats
03:36are almost always red.
03:39This choice isn't random.
03:40It has strategic importance,
03:42which is rooted in visual science.
03:44The thing is,
03:46red light has a longer wavelength.
03:47It means that it's the first color
03:49to disappear in low light.
03:51It allows the audience
03:52to concentrate better on the screen
03:53once the movie begins.
03:55Such a design choice
03:56enhances the viewing experience
03:58by minimizing distractions.
04:01Speed bumps are crucial
04:02for pedestrian safety,
04:04but at the same time,
04:05they can seriously increase car emissions
04:07due to the non-stop acceleration
04:09and deceleration they cause.
04:13To address this issue,
04:14some cities like London
04:15are testing fake speed bumps.
04:17Those are optical illusions
04:19painted on the road.
04:20They look raised
04:22from a driver's perspective,
04:23but in reality,
04:24they're flat.
04:25Authorities hope that this approach
04:27will slow down drivers
04:28without having a negative impact
04:30on the environment.
04:33Soda bottles are always filled
04:35in such a way
04:36that there's some space
04:37between the liquid and the cap.
04:39That's because soda contains
04:40carbon dioxide.
04:41It's a gas that can expand
04:43once the bottle's heated.
04:44If there's no gap in the bottle,
04:46it can break
04:47because of the pressure
04:48building inside.
04:50Also, when you open your drink,
04:52the gases go out
04:52in the form of bubbles,
04:54making the drink overflow.
04:55The gap helps
04:57with this problem, too.
05:00The USB symbol,
05:01looking like a trident,
05:03has always sparked
05:04multiple speculations
05:05about its origin.
05:07One popular idea
05:08is that it represents
05:09Neptune's trident
05:11and symbolizes power
05:12and adaptability.
05:13But there's also
05:14a little bit less
05:16exciting theory.
05:17A man who claimed
05:18to have designed the symbol
05:19in the 1980s
05:20stated that it was supposed
05:21to represent connectivity.
05:23The large circle
05:24symbolizes a computer,
05:26while the attached shapes
05:27– the circle,
05:28the triangle,
05:29and square –
05:29stand for different outputs.
05:33The design of a tennis racket
05:35has a specific feature
05:36known as the throat.
05:38It's an open space
05:39below the head of the racket.
05:41This space isn't just
05:43for storing balls,
05:44it also improves
05:45the racket's aerodynamics
05:46by letting air pass through.
05:48It seriously reduces drag
05:50during swings.
05:52Speaking of tennis,
05:54tennis courts are usually
05:55built with a north-south
05:56orientation.
05:58It helps minimize
05:59the impact of the sun's
06:00position during the game,
06:01ensuring that neither player
06:03has the sun directly
06:04in their eyes.
06:06Look closely
06:07at a tram's overhead lines
06:09and you'll see
06:10that its contact wires
06:11zigzag back and forth
06:13instead of going
06:13in a straight line.
06:15That's because all trams
06:16have pantographs
06:17attached to their roofs.
06:19The upper part
06:20of the pantograph
06:21is gradually worn down
06:22by the overhead wire
06:23and eventually
06:24needs to be replaced.
06:26To wear it down evenly,
06:28the wire is not
06:29installed strictly
06:30along the tram's path,
06:32but in zigzag patterns.
06:34As the tram moves,
06:35the pantograph slides
06:37along the wire
06:37and it wears down evenly.
06:41Those cone-shaped
06:42water cooler cups?
06:44Their shape
06:45is intentionally designed
06:46to prevent users
06:47from setting the cups down.
06:48This allows employees
06:50to minimize the risk
06:51of spilling water
06:52on their desks
06:53around various
06:53electronic devices.
06:55Plus,
06:56less material
06:56is used to produce
06:57cone-shaped cups,
06:58which makes the process
06:59less wasteful
07:00and more cost-effective.
07:02It also kind of
07:04supports sustainability
07:05by encouraging people
07:06to drink their water
07:07quickly and dispose
07:08of their cups
07:08immediately after.
07:12Most suitcases
07:13have two zipper pulls
07:14and it serves
07:15several purposes.
07:17First of all,
07:18if one zipper fails,
07:20the other can keep
07:21the suitcase closed.
07:22Even better,
07:23having two zippers
07:24allows you to have
07:25easier access
07:26to small sections
07:27of your suitcase
07:28without having to
07:29open it entirely.
07:31And finally,
07:32when you have two zippers,
07:33you can connect them
07:35with a padlock
07:35for increased security.
07:39Some plastic milk
07:40containers have
07:41dents on their sides.
07:42These dents
07:43serve several purposes.
07:45When milk spoils,
07:46it usually causes
07:47swelling and high-pressure
07:48buildup inside the container.
07:50That's when the dent
07:51pops out
07:52and doesn't let
07:52the jug blow up.
07:54Plus,
07:55if you decide
07:55to freeze the milk,
07:56it will expand
07:57like any other fluid.
07:59And then again,
08:00the indentation
08:01will pop out
08:02and prevent the container
08:03from breaking
08:04inside your freezer.
08:07If you ever had
08:08a problem figuring out
08:09why fake pockets exist,
08:11you need to hear this.
08:13The main reason
08:14is that if a clothing item
08:16has a specific cut
08:17or shape,
08:18pockets may spoil it.
08:19They can alter
08:20the item's shape
08:21either in the warehouse
08:22or already on
08:23the retail rack.
08:24The solution?
08:26Getting rid of the pockets
08:27in key areas.
08:28Plus,
08:29fake pockets
08:30are obviously cheaper
08:31and they don't
08:32get stretched out.
08:34The thermos
08:35wasn't actually invented
08:37to keep your coffee warm.
08:39It was made
08:40by a Scottish scientist
08:41who wanted
08:41a safe place
08:42to keep his chemicals
08:43at a stable temperature.
08:45So,
08:46he took two bottles,
08:47put the smaller one
08:48inside the bigger bottle
08:49and vacuumed out
08:50the air between them.
08:55Crackers have holes
08:56in them
08:56to stop them cracking
08:57and breaking
08:58during baking.
08:59If the holes
09:00weren't there,
09:01steam would build up
09:02inside the cracker
09:03and make it collapse.
09:05Take a look
09:06at a soda bottle
09:07and you'll notice
09:08a disc inside
09:09the bottle cap.
09:10This helps seal in
09:11the liquid
09:11and the drink's fizz,
09:13stopping it
09:14from going flat.
09:15The long neck
09:16on your soda bottle
09:17is designed like that
09:18to encourage you
09:19to hold it there.
09:20That way,
09:21the heat from your hand
09:22will only warm
09:23that top bit of the bottle
09:24instead of heating up
09:26your whole drink.
09:27It's always hard
09:29to see your food
09:29in the microwave
09:30because of that pesky
09:31black grate
09:32on the window.
09:33But it's there
09:34to stop harmful microwaves
09:35from escaping.
09:37Called the Faraday Shield,
09:39it protects you
09:39as well as ensures
09:41that your food
09:41cooks properly.
09:43Food items like chips
09:44come with about
09:4543% nitrogen
09:46inside their package.
09:48It might seem like
09:49they sell you
09:50half a bag of air,
09:51but it's exactly
09:52the opposite.
09:53Oxygen,
09:54the gas we breathe,
09:55would react with the chips
09:57inside the bag
09:57and make them
09:58go rancid quickly.
10:00It's called oxidizing
10:01for a reason.
10:03Nitrogen,
10:03on the other hand,
10:04is an inert gas
10:05that helps keep
10:06the foodstuffs fresh
10:07and also protects them
10:09from breaking
10:10during transportation.
10:11A bag of chips
10:12that has this gas cushion
10:14lets you enjoy
10:15your crunchies
10:16without them turning
10:16to potato crumbs.
10:18Donuts have holes in them
10:20so that the inside
10:21and outside cook evenly.
10:23Before the holes
10:24were added,
10:25the inside would often
10:26be greasy
10:26and doughy
10:27while the outside
10:28was crisp.
10:30Margins on paper
10:31aren't for writing
10:32in dates
10:33and numbering lists.
10:35They were originally
10:35added to serve
10:36a protective function.
10:38Back in the day,
10:39rats used to be
10:40a pesky problem
10:41in people's homes
10:42and paper
10:43was one of their
10:44favorite snacks.
10:45Margins were added
10:46as a safeguard
10:47so that the rats
10:48would nibble
10:49on blank paper
10:50rather than taking
10:51a bite out
10:52of your important work.
10:53That hole
10:54in your hollow lollipop stick
10:56isn't to prevent choking
10:57should it ever be swallowed.
10:59It's actually there
11:00to keep the candy
11:01in place.
11:02Excess candy
11:03flows into the hollow tube
11:05and the hole,
11:06which when it hardens,
11:07keeps the pop in place.
11:09If it was a smooth stick,
11:11the candy would
11:12slide off easily.
11:13Vacuums come
11:14with so many attachments,
11:16but do any of us
11:17really know
11:18what that one
11:18with long bristles
11:19is for?
11:20It's for dusting
11:21and is perfect
11:22for cleaning
11:23framed art,
11:24blinds,
11:24and lampshades.
11:26What's the difference
11:27between a wooden hanger
11:29and a plastic one?
11:30Aside from helping
11:31keep your clothes
11:32in shape,
11:33cedar wood hangers
11:34also repel
11:35moths and bugs.
11:37Salt isn't just
11:38used for cooking.
11:39It can get rid
11:40of tough smells.
11:41Rubbing salt
11:42on your fingertips
11:43after chopping garlic
11:44should remove the smell.
11:46It also works
11:47on shoes.
11:48Toasters
11:49have a secret slide
11:50in the bottom
11:51that can be removed
11:52so you can clean out
11:53all those annoying
11:54breadcrumbs.
11:56If you ever had problems
11:57with popping chocolates
11:59from the box,
12:00look at those little holes
12:01around them.
12:02They're there
12:02to help you.
12:03If you push a hole
12:05right next to the candy,
12:06it'll jump out easily.
12:08When you take a sip
12:09from a coffee cup
12:10with a lid,
12:11it decreases air pressure
12:13inside the cup
12:14so air tries to get in.
12:16The tiny hole
12:17on the lid
12:17allows air
12:18to enter that way
12:19so liquid
12:20can smoothly
12:21pour out the main hole.
12:23More on beverage lids.
12:25The small button
12:26on them
12:27let restaurant workers
12:28and customers too
12:29understand what's in a cup.
12:32Near each button,
12:33there's a name.
12:34Just look
12:35at which one
12:36is pushed down.
12:37The numbers
12:38on the fruit stickers
12:39tell you how
12:40exactly they were grown.
12:41If there are
12:42four digits
12:43and the first
12:44is four
12:45or three,
12:46the fruit
12:46has been sprayed
12:47with pesticides.
12:49If there are
12:49five digits
12:50and the first
12:51is nine,
12:52the fruit
12:52has been grown organically.
12:54If there are
12:55five digits
12:56and the first
12:57is eight,
12:58the fruit
12:59has been genetically modified.
13:01When you're
13:02on your way back
13:03to the car
13:03after bagging up
13:04everything you bought,
13:05use loops
13:06on a shopping cart
13:07to hang the bags.
13:09Now,
13:09softer items
13:10like bread,
13:11eggs,
13:12fruit,
13:12and veggies
13:13won't get squashed
13:14by the heavier goods.
13:16If you don't have
13:17anyone to hold
13:18the other end
13:19of your tape measure
13:20when you try
13:20to measure something,
13:22tap a nail on it.
13:23Now,
13:24simply hook
13:25your tape on it
13:26using the tiny hole
13:27all tape measures have.
13:29The square-shaped spoon
13:31that goes with
13:32a McFlurry
13:33helps to mix
13:34the ice cream toppings
13:35through the dessert.
13:36The spoon hooks
13:37directly to a machine
13:38and spins around.
13:41Padlocks
13:41that are used
13:42outside
13:43quickly get out
13:44of order
13:44because of rain.
13:46See this little hole
13:47in the bottom?
13:47It's made for
13:48pouring engine oil
13:49inside.
13:50Do this
13:51and the key
13:52will again turn
13:53in the lock
13:53without any difficulty.
13:56You keep banging
13:57the bottom
13:57of a glass ketchup jar
13:59but nothing's coming out.
14:01Here's a little tip.
14:02Turn your ketchup bottle
14:03at an angle
14:04and tap
14:05on the middle
14:06of the neck.
14:07In many
14:08fast food restaurants,
14:09customers fill
14:10tiny folded paper cups
14:12to get a portion
14:13of ketchup
14:13or mustard.
14:15Here's the news.
14:16The cups
14:16are supposed to unfold
14:18and turn
14:18into small paper platters
14:20to hold
14:21a great deal
14:21more sauce.
14:23That little hole
14:24on the handle
14:25of a pot
14:25or a frying pan
14:26isn't just
14:27for hanging them
14:28on the wall.
14:29During cooking,
14:30put the end
14:31of your utensil
14:32in the hole
14:32and it'll be propped
14:34over the pot
14:34to save your kitchen
14:35from extra mess.
14:37The blue
14:38or any other
14:39dark color bristles
14:40on your toothbrush
14:41are meant to remind you
14:42when it's time
14:43to get a new one.
14:44If you see
14:45that bristles
14:45have become pale,
14:47change the toothbrush
14:48or its head.
14:49An extra hole
14:50at the upper part
14:51of the sink
14:52has multiple
14:53hidden functions.
14:54First,
14:55in case someone
14:56forgets to close
14:57the tap,
14:58the water won't
14:58overflow
14:59and the bathroom
15:00won't get flooded.
15:02Second,
15:03thanks to that hole,
15:04the water drains
15:05faster
15:05as it gives
15:06an escape
15:07for the air
15:07helping the water
15:08flow down.
15:10Most metallic zippers
15:11have a hidden lock
15:12inside them
15:13to save you
15:13from awkward situations
15:15such as an undone fly.
15:17Don't leave
15:18the zipper handle
15:18in an upward position.
15:20When you pull it
15:21downwards,
15:22it automatically locks.
15:23It's all thanks
15:25to those tiny grooves
15:26hidden underneath
15:27the handle.
15:29Spoiled milk
15:30emits gases
15:31like most foods
15:32when they go off.
15:33A classic plastic milk jug
15:35has a concave shape
15:36on one side.
15:37So when the gases
15:38expand inside the jug,
15:40it expands too
15:42and the concave shape
15:43curves out.
15:44Also,
15:45if you want to save
15:46some milk for later
15:47and freeze it,
15:48the jug will expand
15:49when the milk gets
15:50solid as well,
15:51occupying more space
15:52in a jug.
15:54Bath foam
15:55isn't only for fun
15:56or a nice smell.
15:57It also helps regulate
15:59the temperature.
16:00The bubbles keep
16:01the water hot
16:02so you can enjoy
16:03a bath
16:03a bit longer.
16:04Anyway,
16:05it works for acrylic
16:06bathtubs only.
16:07Those made of metal
16:08lose heat really fast
16:10either way.
16:12Many cups and mugs
16:13have little grooves
16:14on the bottom
16:15on purpose.
16:16They're designed
16:17for washing machines.
16:18The grooves
16:19let the water flow
16:20and not spill over
16:21your feet
16:22when you take
16:22the cup out.
16:23Also,
16:24those grooves
16:25let the air flow
16:26so the cup doesn't
16:27crack
16:27even if the tea
16:29is scalding.
16:30a point
16:31on an ointment cap
16:33is there
16:33for a reason too.
16:34Most tubes
16:35are usually
16:36sealed with foil
16:37and it's better
16:38to avoid opening
16:39it with fingers
16:39unless you're ready
16:40to say goodbye
16:41to your nails.
16:42A point
16:43easily opens
16:44even the most
16:45safely sealed tube.
16:47Escalator brushes
16:48aren't for keeping
16:49your shoes clean
16:50and polished.
16:51It might be tough
16:52to apply wax
16:53right on that brush
16:54while the escalator
16:55is on the move.
16:55It's for your safety.
16:57Brushes won't let you
16:58come close to the edge
16:59so a long coat
17:00or boot cut jeans
17:02won't end up
17:03in between the steps.
17:05All Tic Tac containers
17:07are designed
17:08to dispense
17:09one Tic Tac
17:09every time you open it.
17:11The lid has the same
17:13shape as the candy.
17:14Turn the container
17:15upside down
17:16gently shake it
17:17and slowly open it.
17:19You'll notice
17:19only one candy
17:20stuck between
17:21those lid grooves.
17:22So if you just
17:24open the container
17:24and shake it
17:25until five
17:26or even more candies
17:27fall into your mouth
17:28it means you've been
17:30eating Tic Tacs
17:31wrong all this time.
17:32The pom-pom
17:34on top of your beanie
17:35wasn't put there
17:36as a fashion accessory.
17:37The pom-pom
17:38was originally
17:39added to the hat
17:40to prevent sailors
17:41from banging their heads
17:42on the ceilings
17:43of the ship
17:43that were too low.
17:45Have you ever wondered
17:47what these extra holes
17:48at the top
17:48of your running shoes
17:49are for?
17:50They're designed
17:51so that you can tie
17:52the shoes
17:52in multiple different ways.
17:54That's useful
17:55when you want
17:55to compensate
17:56for things
17:56such as a bad stride
17:58or even a damaged toe.
18:01Plus,
18:02you can change
18:02the look of your shoes
18:03the way you prefer.
18:07the tip-tack dispenser.
18:07Many people use a dust jacket
18:09of their book
18:09as a bookmarker.
18:11No problem with that.
18:12It will save your book
18:13from bent page corners.
18:14But the primary purpose
18:16of a dust cover
18:17is to keep the book safe
18:18from distortions.
18:20For instance,
18:21if you spill juice
18:21or drop some of the food
18:23on your book
18:23while reading it.
18:26The tip-tack dispenser
18:27has this little groove
18:28on its top
18:29so you can dispense
18:30only one tip-tack
18:31at a time.
18:33Even though,
18:33let's be honest here,
18:34nobody does that.
18:35Most of us just spill
18:36a whole bunch at once
18:38and then we wiggle
18:39all those extra
18:40tip-tacks back in.
18:43Those rubber bumps
18:44you see between
18:44the tire treads
18:45are there for your safety.
18:47The raised edges
18:48tell you what the minimum
18:49height of your tread is.
18:51If the bump
18:52and the edges
18:52are even,
18:53it's time for you
18:54to visit the tire shop
18:55as soon as possible.
18:57But if the bumps
18:58are well beneath
18:59the level of the edges,
19:00you're good to go.
19:03What about that black grating
19:04on the microwave window?
19:06It's something called
19:07a Faraday shield
19:08and it's there
19:09to prevent microwaves
19:11from getting away
19:11and turning the entire room
19:13into a Faraday cage.
19:14If the microwaves escape,
19:16your meal won't
19:17cook properly either.
19:18So yep,
19:19the cage is not there
19:21to make it difficult
19:21for you to see your meal
19:22while it's cooking.
19:23It's keeping
19:24the electromagnetic energy
19:25inside.
19:28How about a wrench
19:29compatible screwdriver?
19:31Cover your screwdriver
19:32with the end of your wrench
19:33and you can increase
19:34its torque.
19:35That's why the head
19:36of your screwdriver
19:37is designed
19:38the way it is.
19:39When you have
19:40odd angles,
19:41you can use this strategy.
19:44You've probably heard
19:45those myths,
19:45the blue side
19:46of the eraser
19:47can erase the pen.
19:48False.
19:49Its purpose
19:50is to erase a pencil
19:51but in case
19:52you're writing something
19:53on heavier paper.
19:55The blue side
19:56can remove smudges
19:57you see
19:57after using
19:58the pink eraser too.
20:01Have you ever wondered
20:02why oranges
20:03in supermarkets
20:04mostly come
20:04in the red mesh bag?
20:06It's a trick
20:07to make this food
20:08look more orange
20:09and encourage you
20:10to make a purchase.
20:11An extra tip,
20:12don't throw away
20:13the mesh bag.
20:14Tie it up
20:15so you can have
20:15a small pot scrubber
20:16to clean your sink,
20:18kitchen,
20:18appliances,
20:19and dishes.
20:22You can see
20:23golf balls
20:24don't have
20:24a perfectly round shape.
20:26Their surface
20:27is covered
20:27with many little dimples,
20:29something golf balls
20:30didn't always have.
20:31At one point,
20:32experienced golfers
20:33started noticing
20:34how through time,
20:36older balls
20:37with imperfections
20:38such as nicks
20:39and bumps
20:39could travel further.
20:41Such things
20:43create turbulence
20:44in the air
20:44around the golf ball
20:45which eventually
20:46reduces drag.
20:48So,
20:49manufacturers
20:49started producing
20:51balls with dimples
20:52so they could go
20:52farther and faster.
20:55You might have noticed
20:57that sometimes
20:57there are ridges
20:58in toothpick tops.
20:59It's more hygienic
21:00because when you
21:01break that off
21:02you can prop
21:02the toothpick up on it
21:04and it won't touch anything.
21:08Another safety feature
21:09you'll find,
21:10this time in your car,
21:12is a tab
21:12on your rear view mirror.
21:14With it,
21:15you can change
21:15the position
21:16of the mirror
21:16so you don't get blinded
21:18if there's a car
21:18behind you
21:19with its high beams on.
21:21So,
21:22this little tab
21:22helps you control
21:23the glare of lights
21:24coming from behind.
21:25This feature showed up
21:27in the 1930s
21:28but in the early 1970s
21:29it became a part
21:31of standard equipment
21:32in most trucks
21:33and cars.
21:35Do you see
21:36that tiny hole
21:37on your iPhone
21:38right next to
21:38the rear-facing camera?
21:40It's a microphone
21:41and it's there
21:42so your phone
21:42can record sound
21:43as you turn
21:44your camera around.
21:48Some cables
21:49have a thick cylinder
21:50towards the end
21:50of the cord.
21:51It's called
21:52a ferrite core
21:53or a choke.
21:54It's a magnetic
21:55iron oxide
21:56that stops
21:57high-frequency
21:58electromagnetic interference.
22:00For example,
22:01you know that
22:02annoying static noise
22:03you get
22:04if you bring your phone
22:04too close to a speaker?
22:06This interrupts
22:07your call
22:08which is why
22:08cable cords
22:09with big cylinders
22:10are pretty useful
22:11because they prevent
22:12these things.
22:15Do you know
22:16why nearly all
22:17luggage bags
22:17and backpacks
22:18have two zippers?
22:19It's way more
22:20convenient
22:21and easier to open
22:22in that way
22:22but not just that
22:24you can also
22:25lock these two
22:26zippers together
22:26to keep the stuff
22:27inside your bags
22:28safer.
22:30You know
22:31how toilets
22:32at public spots
22:33like malls
22:34have those big
22:35gaps at the bottom?
22:36It's primarily
22:37for better
22:38circulation of air.
22:39This type of door
22:40also makes it easier
22:41to clean the toilet
22:42or check if it's
22:44occupied
22:44if you're standing
22:45in line.
22:46Other than that
22:47if you get stuck
22:48there
22:48and the lock
22:49gets broken
22:50you still have
22:51a way to escape
22:52you can just
22:53crawl out.
22:55Ever notice
22:56those plastic
22:57end caps
22:57on utility knives?
22:59And they also
23:00have scales on them
23:01which indicates
23:02you may use
23:03them multiple times
23:04but with sharp
23:05edges.
23:07You can separate
23:08the blades
23:08through these
23:08plastic end caps
23:09then you can
23:11move the slider
23:12and bring the
23:12sharp blade
23:13to the front.
23:14If you've ever
23:15taken a moment
23:16to examine
23:17a regular grocery
23:18cart
23:18especially their
23:19fold-out section
23:20you probably
23:21notice those
23:22metal loops
23:23jutting out.
23:24They're designed
23:25to protect the
23:25items you carry
23:26in your cart.
23:28You can use
23:29them to hang
23:29bags with
23:30soft items.
23:31You don't
23:32want to
23:33accidentally
23:33squish with
23:34heavier products
23:34like bread
23:35or easily
23:36breakable things
23:37like eggs.
23:40Many coffee
23:41mugs come
23:41with curved
23:42notches on
23:43their bottom.
23:43When you're
23:44washing your
23:44mugs, put
23:45them against
23:46the rack at
23:46an angle
23:47in your
23:47dishwasher.
23:48This way
23:48the water
23:49won't pool
23:49in there
23:50so your
23:51favorite cup
23:51will be
23:51completely dry
23:52by the time
23:53you take
23:53it out
23:53of the
23:54dishwasher.
23:56If you're
23:56a McFlurry
23:57fan, you've
23:58probably noticed
23:59there's a
24:00square hole
24:00in the
24:01handle of
24:01the spoon.
24:02It's there
24:03so you can
24:03attach it to
24:04the special
24:04machine that
24:05mixes the
24:05ice cream
24:06and your
24:06favorite
24:07toppings
24:07together.
24:08The machine
24:09has a bar
24:10that slips
24:11into this
24:11square-shaped
24:12spoon and
24:12then thoroughly
24:13stirs it.
24:14And you get
24:15the spoon
24:16so they can
24:16minimize the
24:17mess during
24:18the process.
24:19Quite neat,
24:20wouldn't you
24:20say?
24:22A regular
24:23milk jug
24:23has a
24:24dent on
24:24one side.
24:25Some might
24:26see it as
24:27a random
24:27design decision,
24:28but a
24:28dent has
24:29several
24:30purposes.
24:31One of
24:32them is
24:32to get
24:32bigger if
24:33there's a
24:33gas buildup.
24:34This happens
24:35when your
24:35milk is
24:36spoiled.
24:37So you
24:37don't even
24:38have to
24:38try to
24:38check this
24:39out.
24:40Also,
24:40the dent
24:41is there
24:41so the
24:42jug doesn't
24:42burst if
24:43you accidentally
24:44drop it.
24:45The dent
24:45allows the
24:46expansion space
24:47that deals
24:47with the
24:48sudden
24:48pressure
24:48that happens
24:49when you
24:50drop the
24:50jug.
24:52Dental
24:53floss.
24:54Sure,
24:54it's important
24:55for your
24:55dental health
24:56and it's
24:56easy to
24:57assume what
24:57you do
24:57with it,
24:58but dental
24:59floss is
24:59great in
25:00the kitchen
25:00as well
25:01because it's
25:02a very
25:02precise cake
25:03slicer,
25:04way better
25:05than a
25:05regular
25:05knife.
25:08Most
25:09kitchen
25:09shears have
25:10a serrated
25:11opening right
25:12there at the
25:12center where
25:13the blades
25:13and handles
25:14meet.
25:15It's
25:15something you
25:16can use to
25:16trim difficult
25:17herbs such
25:17as rosemary,
25:18thyme,
25:19or chives.
25:20Because of
25:21this opening,
25:22you don't need
25:22to pick the
25:23leaves off by
25:23hand,
25:24but de-stem
25:25them in one
25:25motion.
25:28The majority
25:29of gelatin
25:29containers or
25:30single-serving
25:31yogurts come
25:32with a tinfoil
25:33lid and in
25:34most cases,
25:35you can use
25:35this covering
25:36as a disposable
25:37spoon.
25:38Just peel away
25:39the covering and
25:40after a couple
25:41of simple
25:41folds, you'll
25:42have a perfect
25:43little spoon for
25:43your midday
25:44snack.
25:46Well, it's a
25:47nice Sunday
25:48afternoon and
25:48you're shopping
25:49at your regular
25:50grocery store
25:51when you stumble
25:52upon a bloated
25:53package in the
25:53fresh produce
25:54aisle.
25:55You check the
25:56product information.
25:57It seems well
25:58within its
25:58expiration date.
25:59Then, why the
26:01unusual shape,
26:02you may wonder?
26:03The answer is
26:04not always
26:05straightforward.
26:06For some
26:06types of fresh
26:07products, such as
26:08meat, fish, or
26:09seafood, sometimes
26:10even salads and
26:11cheese, scientists
26:12came up with
26:13something called
26:14MAP, or
26:15Modified Atmosphere
26:16Packaging.
26:17To ensure that
26:18these types of
26:19products with a
26:20relatively short
26:21shelf life stay
26:22fresh for as long
26:23as possible, a
26:24combination of
26:25gases is introduced
26:26in the packaging.
26:28It happens even
26:29before the product
26:30reaches your local
26:31grocery store.
26:32A French professor
26:33at the Montpelier
26:34School of Pharmacy
26:35stumbled upon this
26:36method after he
26:37noticed that fruits
26:38tend to stay fresh
26:39for longer periods
26:40of time in low
26:42oxygen storage
26:43conditions.
26:44The types of
26:44gases in MAP
26:45packaging can vary
26:46from product to
26:47product, but the
26:48main idea is to
26:49replace or reduce
26:51the content of
26:51oxygen.
26:52It's generally
26:53replaced with either
26:54nitrogen or carbon
26:55dioxide.
26:56Keep in mind that
26:57just because a
26:58bloated bag of
26:59salad is within its
27:01expiration date, it
27:02doesn't mean it's
27:03always safe to eat.
27:04The gases inside the
27:06bag may very well be
27:07there for their own
27:08purpose, but they can
27:09also be a sign that
27:11the product is spoiled.
27:12That's why the best
27:14course of action
27:14when shopping would
27:16be to check if the
27:16product is not
27:17expired.
27:18If it's still within
27:19the day, check for
27:20any unusual odors or
27:22damage to the
27:23packaging.
27:24If something seems
27:25off, it's best not
27:26to risk it.
27:27You can reach out to
27:28any of the store
27:29staff if you have any
27:30questions or concerns.
27:31Most supermarkets
27:33these days have a
27:34layout which allows
27:35for a logical
27:36shopping order, like
27:37buying non-perishable
27:38items first, then
27:40adding refrigerated or
27:41frozen products.
27:42Fruits and vegetables
27:43should come last since
27:45you won't want them at
27:46the bottom of your
27:46shopping cart.
27:47Nobody likes a
27:49squished tomato.
27:50While I'm on the
27:51subject of fruits and
27:52veggies, try to get
27:53them earlier in the
27:54morning if possible.
27:56Veggies that have been
27:57sitting out all day
27:58may lose some of their
27:59shape and texture,
28:00while others may be a
28:02bit wilted away.
28:03Quick tip on waste
28:04management, never buy
28:06more produce than you
28:07intend to use in a
28:08week.
28:09Most fruits and
28:09vegetables don't even
28:10last that long, so it's
28:12best not to give in to
28:13cravings.
28:14Shopping on a full
28:15stomach might help with
28:16that as well, just as
28:18much as going shopping
28:19with a pre-made list of
28:20things you need to buy.
28:22Thoroughly inspecting the
28:23package of every product
28:25might save you some
28:26hustle later as well.
28:28Refrigerated products
28:29need to feel cold to the
28:30touch, whilst frozen
28:32ones need to be solid and
28:33with no sign of leakage.
28:35When you get home, make
28:37sure you refrigerate all the
28:38necessary items as soon as
28:40possible.
28:41Generally, they shouldn't be
28:42out of the refrigerator for
28:43more than two hours.
28:44Otherwise, their quality
28:46won't stay the same.
28:47Buying potted herbs from the
28:49grocery store may not be the
28:51first thing on your list,
28:52but it's surely something to
28:53consider.
28:54Not only are they available for
28:56a fraction of the cost, but
28:58they're also easy to grow and
28:59take care of.
29:00Just picture a nice herb garden
29:02right there on your balcony or
29:04even in the kitchen.
29:05Wouldn't that be nice?
29:07You'll always have fresh basil
29:09atop a mouth-watering pasta
29:10dish.
29:11Since you're still at the
29:12grocery store, pick up some
29:14coffee filters while you're
29:15at it.
29:15You may not have a machine at
29:17home that actually uses
29:18filters, but there are a lot
29:20more things you can use them
29:21for around the house.
29:23They can be used for
29:23straining liquids, safely
29:25stacking delicate china in
29:27your cupboards, or even
29:28polishing windows or shoes for
29:30that matter.
29:31If your favorite fruits and
29:32vegetables are on sale, but
29:34buying large quantities would
29:36mean they go to waste,
29:37consider freezing them.
29:39You can stock up on items for
29:41smoothies, especially for the
29:42colder season when there are
29:44limited options for fresh fruits.
29:46And don't just grab the first
29:47thing on the shelf, especially
29:49if it's likely to go bad
29:50quickly.
29:51Stores restock their produce
29:53following a first-in, first-out
29:55layout, so the items at the back
29:57of the shelf will always be a
29:59tad bit fresher.
30:01The same goes for tea if you
30:02prefer it to coffee.
30:03Switch to buying loose-leaf
30:05tea, and you'll not only
30:06reduce the cost, you'll also
30:08be able to make your own
30:09homemade tea blends.
30:11Loose-leaf tea also has a
30:13stronger flavor than tea sold
30:14in teabags.
30:15As for the other household
30:17stuff, stock up on items such
30:19as light bulbs, paper towels,
30:21or batteries.
30:22Chances are you'll always be
30:24needing at least one of these
30:25items, so it's best to buy
30:26them in larger quantities when
30:28on sale.
30:28They never go to waste, and
30:31let's face it, it's always
30:32annoying when you run out of
30:33batteries at home and your TV
30:35remote stops working.
30:37Hey, tell me about it.
30:38Try to reduce the number of
30:40times you go to the grocery
30:41store to buy just one item.
30:43It's inefficient, and most
30:45likely, you'll end up buying
30:46things that you don't actually
30:48need.
30:48That shopping list starts to
30:50make a lot more sense now,
30:52doesn't it?
30:53Another list worth making, the
30:55one containing whatever you have
30:56in the fridge, try to create
30:58such a list at least twice a
31:00week.
31:00Meal planning for at least a
31:02week in advance will also help
31:04you reduce impulse buying.
31:05If you already know what you'll
31:07want for dinner on Wednesday,
31:09why add anything else to the
31:10cart if it's unnecessary?
31:12At the same time, start getting
31:14creative with your leftovers.
31:16There's no need for them to go to
31:18waste when you can mix and match
31:20or add some additional herbs and
31:21flavors to spice them up.
31:23Store leftovers in transparent
31:25containers for added visibility,
31:27and don't be afraid to set out a
31:29leftover day during the week.
31:31It's also nice to look at them as
31:33ingredients rather than leftovers.
31:36Use extra leftover pasta or
31:38steamed vegetables for a frittata
31:40or an omelet.
31:42Blend together cooked vegetables with
31:44some tomatoes to create a pasta sauce.
31:46Put together some wraps for the next
31:48day's lunch with anything from
31:50leftover cooked rice to meat and
31:52vegetables. Or if you're really
31:54looking for the easiest method to
31:56save leftovers, you can always turn
31:58them into soup. Last night's
32:00vegetable side dish can turn into a
32:02wholesome lunch if you simply add a
32:04can of broth and blend it all
32:06together. Even a two-day-old loaf of
32:09bread can be salvaged if you cut it
32:11diagonally, sprinkle the slices with
32:13some herbs and olive oil, and pop them
32:15in the oven for a couple of minutes.
32:17You'll then have yourself some nice
32:19homemade croutons for that previously
32:21mentioned soup. A little label know-how
32:24never hurt anyone either. Be on the
32:26lookout for ingredients you've never
32:28heard of or those you can't pronounce.
32:30An item that usually has more than five
32:32ingredients listed on the packaging
32:34should be avoided. Even the way you
32:37carry your groceries in the supermarket
32:39can affect how and what you buy. If you
32:42prefer baskets to shopping carts, you're
32:44more prone to impulse searches. That's
32:47with a study published by the Journal of
32:49Marketing Research claims. It happens
32:51due to the effort you put in actually
32:53carrying the items around. Choosing a
32:56shopping cart will most likely make you
32:57comfortable enough to browse through
33:00enough products and read labels
33:02thoroughly. When your grocery list is not
33:04too big, go for the self-checkout aisle
33:06if available. Studies have shown that
33:09impulse purchases are lowered by up to
33:1132% if you actually scan your own items on
33:15the way out. That's because the regular
33:17checkout line is specially designed to
33:19keep you from letting go of any items
33:21you might have reconsidered buying. There's
33:24literally nowhere you can put down your
33:26undesired products, outside of your
33:28grocery cart, and if there's anyone else
33:30waiting in line behind you, good luck
33:32sliding out. The food arrangement on the
33:35shelves can also pose a threat to both
33:37your budget and your habits. Since people
33:40are more inclined to buy the items they see
33:42first, the most expensive products are
33:45placed at eye level, and the budget
33:47options are placed on the top and bottom
33:49shelves. Take your time and scan your
33:52aisles of interest. You'll be surprised to
33:54see that most items placed on higher or
33:57lower shelves are often not only more
33:59cost-effective, but also less packed with
34:02additives or artificial flavor. Hey, be
34:05careful. It's a jungle in there.
