Quizplus · Accepted Answer

When the hot can is inverted, the steam inside the can rapidly condenses into water, which reduces the pressure inside the can. This creates a pressure difference between the inside and outside of the can, causing the can to be crushed as atmospheric pressure outside the can pushes it inwards. The cooling effect of the water also contributes to this process, but it is secondary to the rapid condensation of steam.
