Brian,

This somewhat elaborate apparatus makes a pretty nice Maxwell
velocity distribution. However it takes about an hour of time and is
very noisy. So we would introduce the machine and show its concept
towards the end of one lesson and the final stage with the almost
finished distribution at the beginning of the next one. The apparatus
is also very fine for showing the kinetic behavior of particles that
fill a given volume. It's from PHYWE in Germany

Another demo is our famous heat conduction experiment which I once
described in my paper still available from:

http://www.clab.unibe.ch/labview/whitepaper/LV-PhysicsWPScreen.pdf

It's a classic with us by now.

Another nice demo is a transparent Stirling motor from which we
actually measure and display the Carnot cycle while it's running...
and then my all time favorite, our version of the Wollastone
Cryophorus..!

Just some thoughts that might be of some value hopefully.

Regards and best wishes
