Ice Bomb

The ice bomb illustrates the fact that the volume of ice is greater than the volume of an equal mass of liquid water.

Some cold water is poured into a cast iron bomb and a threaded plug is screwed into the bomb so that the bomb is tightly sealed.

The bomb is then placed into a dry ice/aceton slush which is at -77 deg's celcius and will cause the water inside the bomb to freeze.

It takes a short time for water to freeze. When it does, the bomb explodes.

Little bits of the cast iron bomb are left. When the water freezes, tremendous pressure is produced. The pressure is enough to cause this cast iron bomb with more than 1/8th inch thick sides to explode.
