Brownian Motion

Not meant to be shown in the classroom, this video teaches the teacher how to display Brownian motion using microsized polystyrene balls and how to model it with a speaker and Ping-Pong balls. When you use these vivid demonstrations, make sure your physicists understand that they are not viewing microbes in motion, but inanimate objects that jiggle because of the bombardment of water molecules.
