2B30.15 - Crush The Soda Can

Code Number:
Demo Title:
Crush The Soda Can
Air Pressure, Crush Pressure
Area of Study:
Heat & Fluids
Soda Cans, Boiling Water, Hot Plate, Tongs, and Pan with 1 Inch of Cold Water in it.

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.
