What Are Some Engaging Vandergraph Generator Demos for Grade 9 Students?

[qwexor]

Hey guys,

I need to know if anyone knows of any cool demos to do with a vandergraph generator. It is for a grd 9 level class. So far I have pie plates on top of it, bubbles, just holding it to make your hair stand up. The one that I would really want to know how to do is getting a long chain of people holding hands and one touching the generator. I know that you can make them all get a shock, but am not quite sure how this is done. If anyone could give a description that would be great! Thanks!
