Vacuum Gun Still
The kids (and by that, I mean physics teachers age 18-108) have yet to tire of the ping pong vacuum gun. Monday evening's AAPT demo show included one. I like this particular still. Look carefully; the ping pong ball emerged from the PVC tube at the far left and has passed through the first can. It is beginning to pass through the second can. The third can is, as yet, unaware.
