Demo Title: Crush The Soda Can

Condition: Excellent

Principle: Air Pressure, Crush Pressure

Area of Study: Fluids

Equipment: 

Soda Cans, Boiling Water, Hot Plate, Tongs, and Pan with 1 Inch of Cold Water in it.

Procedure:

Put 20 ml of water into a pop can and put it onto the hot plate. Let the water come to a boil and continue for 2 minutes. Quickly take the can off the hot plate with the tongs and invert into the cold water. The can should collapse dramatically. 1-gallon and 5-gallon cans can also be collapsed in this manner.
