factors presents ten things you did not
know they use for number one the hole in
the cover of a ballpoint pen most people
look at the hole in a ballpoint cover
and think it's fair to keep the ink from
drying out
others think that it helps to release
the cover from the pen easier the real
reason for the hole is a safety feature
people love to chew on pen caps if they
chew on a cap without a hole on the top
and it gets stuck in their throat they
could suffocate the hole allows the
person to get enough air until they can
seek medical attention if the hole is
closed up suffocation is a real
possibility number two the hole at the
end of a tape measure if you've ever
used a measuring tape you've likely seen
the hole in the metal piece at the end
what you may not know is that it
actually does have a purpose you won't
always have someone around to hold the
tape measure when you're trying to
measure a large object the hole is the
perfect spot to put a nail that can hold
on to the tape measure while you're
getting a measurement it's much easier
than hoping the measuring tape won't
slip the serrated edge at the end also
has a purpose it's a great way to mark
the spot that you measured when you've
only one hand many people think that
these were just part of the design they
do however actually have a purpose
number three the arrow next to the gas
gauge if you've ever looked at the gas
gauge in a vehicle and saw white arrow
pointing in either direction chances are
you didn't know that it had a purpose if
you're driving a vehicle that you've
never driven before and you need to pump
gas the arrow will tell you what side of
the car the gas tank is on this way
you'll know which sides the pump to pull
up to saves you the trouble of getting
out of the car to check which side the
gas tank is on number four the grooved
side of a bobby pin many people put
their bobby pins in backwards they think
that the tip that flips up is there to
make it easier to pull the bobby pin out
of your hair
that slide actually goes against the
head the grooves are there to help the
bobby pin in your hair stay better
number five the grooves on a utility
blade
if you ever looked at your utility
knives closely you'll notice the lined
grooves on the blade if your blade
starts to get dull you don't need to
throw it away and replace it with a
sharper blade the grooves are there so
that you can break the dull pieces off
and have a fresh sharp blade it can save
you money if you use your utility knife
often and you wear those blades down
quickly number six the hole on a ruler
the holes on a ruler have a purpose that
is not really scientific the holes are
there for convenience the holes make it
possible to hang up the ruler the holes
are the perfect size to hold the head of
a nail this just helps keep things
organized number seven the wings on an
apple power cable if you look closely at
your Apple power cable there are wings
that can flip up these wings make it
easy to wrap up the cord so that you can
travel with it keeping the cord neatly
left when you're ready to plug the
charger in you can flip them back into
their original position these wings make
it much easier to carry a charger in a
purse or a backpack because you don't
need to worry about the wire getting
tangled up and everything else number
eight the hole next to the iPhone camera
if you look at the back of an iPhone
there's a tiny hole next to the camera
this is not an air hole nor is it for
decoration it's actually a microphone if
you're using the back camera to take a
video you need a microphone back there
to pick up the voices and sound this is
what that hole is for if you've ever
noticed these sounds and the videos that
you take with the back camera aren't
muffled well you can fake the small
little hole for that number nine B bump
on the F and J keys on your keyboard the
raised bumps on the F and J on your
keyboard
or so you can put your fingers in the
proper positions without needing to look
down when you feel the bumps under your
index fingers you'll know that your
fingers are in the right place if you
don't feel them you can move your
fingers until you do it's much faster
than trying to line up your fingers by
looking down each time number 10
sneakers over power lines this is one of
the things you probably did not know the
use for that's too
remains a mystery to a lot of people
most people have seen a pair of sneakers
hanging from power lines and they never
knew how they got there or why well
there was a myth that these sneakers
symbolized that there was a gang or a
drug den nearby
well that myth has since been debunked
people have seen sneakers on the power
lines in nice neighborhoods where crime
is not an issue many people believe that
it is to signify something to celebrate
people in the military often do this
when they have completed basic training
some people say it can signify a person
losing their virginity it can also be a
form of bullying or political protest
people will hang their sneakers on the
power lines in front of a person's house
who has different beliefs than them some
people do it just so they can say that
they've done it
the true reason is not known however
people have their own ideas as to why
this ritual is performed subscribe for
