Hey Folks,

I'm looking for inexpensive ("pre-owned" is ok) Van de
Graaff generators that can be easily taken on the road
during traveling science programs. I am also looking
for "care and feeding" guides for VDGs.

The generator should be about 24" tall so that it can
be easily seen during assemblies of 300+ kids.

We have had a lot of problems with "unpredictable" VDG
behavior on the road. Something seems to be shorting
out the globe. I can develop a charge by holding my
fingers about a 1/4" from the belt, but the charge
somehow doesn't make it to the globe (once I remove my
fingers-of course). The rubber belt is exposed on our
Pasco SF-9722 VDG.

Any ideas?
