Ping Pong Ball Explosion

Check out this ping pong ball explosion video. Liquid nitrogen expands quickly from its liquid form into a gas so when put in a confined space the pressure builds up fast.

In this science experiment, liquid nitrogen is poured into a bottle and the cap screwed on tight. See the dramatic results of placing this bottle at the bottom of a barrel and then tipping thousands of ping pong balls on top. Remember that this is a dangerous experiment that needs to be performed by a trained professional in a controlled environment.
