Bottles Broken By Air


Take a square bottle of thin glass, and of any size. Apply it to the

hole of the air-pump, and exhaust the air. The bottle will sustain the

weight of the external air as long as it is able, but at length it

will suddenly burst into very small particles, and with a loud

explosion.



An opposite effect will be produced, if the mouth of a bottle be

sealed so close that no air can escape; then place it in the receiver,

and exhaust the air from its surface. The air which is confined within

the bottle, when the external air is drawn off, will act so powerfully

as to break the bottle into pieces.
