Condition :	Excellent
Principle :	Air Pressure, Crush Pressure
Area of Study :	Heat & Fluids
Equipment :	Soda cans, boiling water, hot plate, tongs, pan with 1 inch of cold water in it.
Procedure :	Put 20 ml of water into a pop can and put 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.
