Clips 7 and 8 are also from S100 programme 5 “Science course unit 5.”

Clip 7  shows a simulation of liquid diffusion. White balls are added to a tray of ball bearings while it is being agitated. This models the liquid diffusion process through which liquids mix through their random motion.

In Clip 8 Dr Walton demonstrates how fast the diffusion process occurs in a gas compared to a liquid.
