hey guys what's up it's Charlie here and
today we're gonna be looking at 10
things you didn't load the useful
these are a few things that you either
used or see every day but you either
never realized the awesomeness of them
or never even thought about it
so check it out and I'm sure you'll
learn something that will change your
life but first be sure to like the video
and subscribe and comment i subscribed
and i'll try to reply so coming in at
number 10 we have published on keyboard
if you're on a computer right now
watching gifts and looks down at your
keyboard and I get you to the F&G keys
have small rectangular box from them
because many of us have grown up with
computers and sisters being there we
don't think about why but the real
reasons of these is because many years
ago when secretaries changed from using
typewriters to keyboard they needed a
way to teach secretaries and other
computer uses the optimum planting
position what you're supposed to do is
let your two index fingers on the keys
and type from there was no this isn't
really used anymore and even have got
better at typing quickly they still put
them on computer so those sons are
simply to help you position your fingers
to type faster
next up we have disc inside bottle caps
if you open up a plastic bottle of water
or soda the chances are you'll see a
small cysts inside the cap most people
don't notice this and those who do you
just assume it's part of the bottle cap
but if you have a pride one of the
particular bottle cap you'll see it's
still close this fine manufacturers
actually make these separately and
they're called sealable did and the
point of it is to keep everything inside
the bottle particularly the cast inside
the portal which keeps them carbonated
because without the available caps soda
would go flat very quickly even though
the small as almost unnoticeable they
serve an important roles and they're
basically the reason for your coach loss
for more than a few hours when the
bottle cap is on
next up we have pocket in underwear
because of health standards the inside
layer of underwear for men and women has
to be made these especially soft tissues
so there is a small profit of the serial
turn into every pair of underwear
most women don't know what the point of
this pocket is and a lot of men don't
even realize that it exists
that's because men's underwear has the
material thrown in between two seems
however because of the shape and the way
women underway is made this isn't
possible without the closest feeling
very
uncomfortable so to keep it comfortable
only one side to be underway is so in
creating a secret pocket
although I wouldn't suggest keeping
changing it or anything mixed up in
white toothpaste cap on a lot of
toothpaste shift at the Capitol small
classics like inside the indented part
of it while many just ignore this and
assume it's part of the unnecessary
design
well this is actually a really cool
hidden design feature that has a really
useful purpose toothpaste manufacturers
actually put these on the cap in order
to pierce the foils in the tooth create
a lot of people are really surprised
when they learned that most people use
the pen or a pin to over me but the
manufacturers got this right into the
toothpaste tube so next time you want to
open your toothpaste try this and you'll
see it's an exact fit they should really
put the speaker out a little better on
the packaging
next up we have a fix on cable tables
are usually seen bits of trouble with
wiring inside them but a lot of laptop
charges and some other cables have
secrets of plastic on them
however this isn't something that people
usually question and the chances are
you've never thought about why will be
soon the same clubs the plastic or
actually called faraq course or chose
they're actually bits of magnetic iron
oxide is used to suppress high-frequency
electromagnetic interference or to put
it in English they used to break up the
frequency of electricity coming into the
cave and the electricity from the other
electronic technologies you have any
advice
this may not sound identified otherwise
the whole world to be full of electrical
interference and computer monitors phone
seekers and televisions to get a static
sound and visual because of the amount
of unsolicited electricity so there you
go
he's 62 people to actually serve a
purpose and quite an important one at
that
next up we have hold in lollipop sticks
if your kid the chances are you really
like lollipop or even adults
I mean come on who's too old for a
lollipop but whatever age you maybe it's
likely that you've noticed the full
holes that are all lollipop sticks and
almost everyone at some point it's
wondered what the two holes on both
sides of the lollipop sticks are for
well they're actually basically the
lollipop on the stairs lollipops are
molded in a specially around the stick
but it wasn't any holes to add friction
and it would just be appalled on the
stick and was fall off as soon as you
put into it so to prevent this from
happening at these two holes use
both of the candidates stuff inside them
there by attaching the rest of the Caddy
to sit next up we have small pocket on
gene gene therapy in fashion for years
and years not only have a fashionable
but they're one of the most practical
and useful pieces of clothing you can
buy and there's one thing jeans are good
for its pocket
we all know about the standard two
pockets in the front and the two pockets
of the back but what's the purpose of
that tiny pocket easily place the part
of the front right pocket
it's a mystery to me but the truth
that's actually really cool the pocket
was designed for cowboys faculty 1800
and it's released by Cowboys to keep
watches in and according to the levi
strauss websites the name of the pocket
it's actually a frontier pocket with
frontier meaning cowboy
despite the lack of cowboys nowadays
jeans companies including is now useless
pocket maybe some nostalgia and 450 of
the design plus that what kid doesn't
want to be a cowboy
next up we have whole intended to know
when you're bored in class or its work
so you start to turn your pain meds
well it's actually used to be very sadly
added killed hundreds of people every
year because people would end up
accidentally swallowing that Henry's and
choking to death so to solve this issue
10 companies forget adding these small
holes to their tennis in order to give
people a better chance of survival in
case they accidentally swallow dependent
if you would follow appended before your
airway would be totally closed off
however the whole means that you can now
breathe a little bit then again I was
still trying to avoid swallow intended
to despite this useful feature
next up we have white part on fingernail
offering an elder made up of three part
firstly the top white layer of dead
fingernail serve the Living main part of
your fingernail and then the bottom
white crescent shaped area of your
fingernail many people don't know what
the point of this part of your
fingernail actually is but it served a
purpose
it's called a luna and if they're tied
the blood vessels in your finger
the reason it's white it's because it's
thicker than the rest of the nail and it
needs to be fixed to protect it as the
damage lumia you can actually result in
a deformed fingernail some people don't
have a loon yellow which can be they
have a low metabolism or too many toxins
in their body and if you have a very
small lunar to the point where you can't
see it
this could mean for your due to fall ill
and next up we have whole in airplane
window
have you ever noticed that tiny hole in
every era
in window for some first-time Flyers
that this can freak them out and looks
like it could be a Fault in the
production of the window however these
are made intentionally and the actual
carpet is to compensate the air pressure
at the air pressure inside the airplane
is very different for the outside of it
and the whole is simply there to
regulate the difference so the outer
window doesn't have to do all of the
work and another reason is because plane
windows which broke up easily when the
so high in the sky but the whole in
airplane windows prevent this as it
allows somewhere to travel through both
sides of the window and regulates
between the warm inside of the plane and
the cold air on the outside check out
