I've been using the Van de Graff in my high school physics class for years. I
have never had a really successful student hair stand on end demo. Does anyone
have the secret. Also, after 25 years I stumbled across the stacked pie pans on
the top of the VDG. I had never done it before. Wow. Instant success. Lead to
lots of discussions, lots of "do it again", and the kids suggested many
alternative things to do. I used small 3-4" Al pie pans upside down and painted
a face on the VDG. Looked like a person with a hat on.
