Crushing Pop Cans With Pressure (No Vapors)

The first part of this demo uses a Pepsi can that has been completely emptied and dried by several hours of intense heating. The result of this is that there is no appreciable amount of water vapors left in the can. The can is then heated on the hot plate and inverted in a beaker of cold water. The can is crushed by atmospheric pressure as the cooling of the air inside the can causes a sudden decrease in pressure. The decrease in pressure results from a decrease in temperature which resulted in slower molecules that collide with the walls of the can less frequently and with less intensity.
