that's first presents 8 things you did
not know the use for number 1 the soft
plastic disk under a soda bottle cap
most people believe that the soft
plastic disk underneath the soda cap is
to keep it from spilling while it can
help with leaks it actually has another
purpose the disc keeps the bottle
airtight which will keep the soda from
going flat if you remove the disc when
you open the bottle the next time you
open it you won't hear the sound when
you open the bottle of all the
carbonation because it'll be gone number
2 the hole beside the back camera on an
iPhone if you've ever looked at the back
of your iPhone you'll see a small dot
next to the camera some people believe
that it is a reset button that is not
the case this small hole is actually a
microphone that is used so that you can
hear what people are saying when you
take a video using the back of your
camera thanks to this small hole you
don't need to worry about having muffled
voices in your videos number three the
hole in a ruler most rulers have a hole
at the top often at the three-inch line
most people don't know the purpose for
this hole it doesn't have a scientific
purpose and it won't help you to make a
straighter line and it won't help you to
measure things either the reason for
this hole is so that you can hang your
ruler on a small nail near your desk
it's just there to make it easier to
store there before the bump on the F and
the J keys on your computer keyboard
most trained typists don't need to look
down at the keys when they type it's
much faster to be able to type without
looking down very often there's a small
bump on the F key and the J key so that
the typist can get their fingers on the
home keys without needing to look down
to find the right place number five the
spike on the top of a tubes cap if
you've ever bought a tube of cream or a
tube of toothpaste you may have noticed
the spike on the top of the cap this is
actually for a purpose oftentimes
there's a piece of protective aluminum
covering the hole want to easily get the
aluminum open you would push the spike
through the protective foil so
you can easily open your - it's much
easier than using a pair of scissors or
a pencil to open the - number six the
arrow next to the gas gauge on your
vehicle if you've ever looked at your
gas gauge you may have noticed that
there's a small arrow beside the gas
tank icon now most people have no idea
what this is for the auto manufacturer
put this arrow on the gas gauge so that
you know what side of the car your gas
tank is on if the arrow points to the
right it means that the gas tank is on
the right side of the car this makes it
easy to pump gas in a rental car or if
you're borrowing a friend's car when you
pull up to the gas pump you won't need
to get out of the vehicle first to check
what side the gas tank is on number
seven the hole in the middle of your
pasta spoon of the eight things you did
not know to use for this is the most
useful and the most misunderstood most
people look at the hole in their pasta
spoon and they think it's there to drain
the hot water well it does do that well
but when testing your pasta to see if
it's done the last thing you want is to
get burns with boiling water right the
hole will drain the hot water yes but it
has another purpose as well the hole is
just large enough to fit one serving of
dry spaghetti now if you don't want to
make the whole box and you'd rather make
just a portion well all you need to do
is fit the spaghetti in the hole there
you go enough for one person number
eight the pen and the nail if you've
ever looked at your nail and noticed a
white spot underneath it means that you
have a calcium deficiency it's very
common and it really is not very serious
if you start taking calcium pills the
white spots should disappear even adding
more milk to your diet could help if
you've ever looked at the ink in certain
pens you might see yellow ink this
actually is not pink it's just a liquid
to keep the pens ink from drying up
quickly it mixes with the Pens ink when
necessary so that your pen will always
write perfectly subscribe for more
