ID Code: I6-21
Purpose: Models gas diffusion through a small hole
Description: White ping pong balls on one side and brightly colored ping pong balls on the other side of a plastic sheet barrier are agitated by a motor which rotates the bottom of the model. Opening a small hole in the plastic barrier between the two sections allows some of the balls to "diffuse" from one side to the other.
