ID Code: I6-35
Purpose: Model gas diffusion.
Description: Balls with two different masses are placed into the demonstrator, one type on each side of a barrier. A diffusion barrier with a small slot is positioned in the center of the device, and the balls are set into motion by vibration of the walls. The balls will mix, representing diffusion. Differences between smaller and larger balls can be observed, and fluctuations can be discussed.
