Description

Visualize air pressure with the help of a wiggling, wobbling, self-rolling pet toy.

Air molecules are too small to see, so it can be hard to imagine how they can apply forces and create pressure. Self-rolling pet toys can wiggle around erratically, pushing and moving objects a lot like air molecules do, modeling many of the behaviors of the molecules in gases.
