BOTTLE BUSTER!
The trick:
To break
the bottom out of a
bottle with your hands.
When you know how, you can break the bottom out of a
pop or beer bottle or even a wine bottle with your
bare hands. Think about it, or if you want to set it
up so that it looks even more impressive, you can
actually drive a nail with the bottoms of some of the best
known brands.
IMPORTANT--- DO NOT ATTEMPT THIS
UNLESS YOU ARE WEARING A GLOVE ON THE "HOLDING" HAND,
GOGGLES AND APPROPRIATE CLOTHING!
It is possible
that the bottle could shatter. Not likely, but
possible.
Please be careful.
The secret to breaking a
bottle with
your bare hands is really pretty
easy.
First you fill the bottle with water,
leaving about
an inch of space at the
top. Then, grasping the
bottle firmly (closer to the top), you hit it sharply
with the palm of the other hand and watch as the
entire bottom of the bottle bursts
off!
IMPORTANT!!! Always perform this out
of doors or where no
one will be
endangered by the glass bursting. It
is
also a good idea to wear a glove on the
hand
grasping the bottle, or to at least
use a towel or
something to protect your
hands. While this trick is
normally
safe, it IS possible for the entire
bottle to
shatter after the bottom pops
off. Protect your hand
with something.
It works best to grasp the
bottle near
the base of the neck (higher than the
picture shows). ALWAYS pick up the glass that breaks and
dispose of it properly.
This is a very impressive
trick that
requires a little practice to get
it
right the first time. You must hit the
top of the
bottle sharply with the upper
palm of the hand (see
illustration). BE SURE YOU HIT THE BOTTLE TOP WITH THE FLESHY
PART OF THE HAND. THE "WEB" OF PADDED FLESH BELOW AND
FORWARD OF THE THUMB.
The bottle bottom breaks
out because you are suddenly forcing and capturing
air in the bottle creating a great deal
of
pressure. You actually force air into
the bottle with
your hand, and then for
just a split second, create
a seal.
Because of this rapid increase of
air
pressure, the bottle can't contain the
forces and breaks
at it's weakest point,
the bottom.
If at
first you don't succeed, give it a
little break.
Don't bruise your hand.
And don't give away where
you hit the
bottle on your hand. When others
try
this, unless they are lucky enough to
hit it just
right, they still won't be
able to do it!
