Analogy for Brownian motion

I was feeding a potato chip to a pool full of small fish and I noticed that as the little fish surrounded the chip and nibbled at it, the chip moved around randomly.  I thought this was sort of an analogy for Brownian motion, where collisions between solvent molecules and small suspended particles causes the particles to move around in a random fashion.

The October, 2012, issue of the Journal of Chemical Eduation came out recently. I have two papers in it: one from work done at Bradley University "Take-Home Nanochemistry: Fabrication of a Gold- or Silver-Containing Window Cling", and the other from work at the University of Texas "New Nanotech from an Ancient Material: Chemistry Demonstrations involving Carbon-based Soot". A picture from the soot research was used for the cover.

Thermal Conductivity Demo

Saw this thermal conductivity demo at the old Lakeview Museum in Peoria yesterday.
