Air pressure Air molecules have a certain mass and when these molecules collide with a surface, pressure is felt on that surface. The molecules in the air contain kinetic energy and are always moving. The moving molecules are always colliding with one another or onto other surfaces creating the phenomenon that we call pressure.
Students gain an understanding of air pressure by using candy or cookie wafers to model how it changes with altitude, comparing its magnitude to gravitational force per unit area, and observing its magnitude with an aluminum experiment. Worksheets provided.

Usually, the air pressure inside an open can is the same as the pressure outside. However, in this experiment, the air was driven out of the can and replaced by water vapor. When the water vapor condensed, the pressure inside the can became much less than the air pressure outside. Then the air outside crushed the can.
