In the crush the can experiment, a soda can was used to show how differences in air pressures may cause the can to “crush” itself. For the experiment, a soda can was obtained and 100 mL of water added. The can was then placed on a hotplate in the”off” position, and then the hotplate was turned on. After waiting for the water in the can to heat to the point where steam could be seen, it was quickly lifted and flipped over into a tub of icy cold water. The resulting reaction was the can crushing. What happened was that as the water inside the can was getting heated, the molecules started to spread and get less dense, and the molecules started to leave the can. The outside air, though, was cooler than the air inside the can, so the molecules of
