I am about to do the Van de Graaff generator demo. I have tried it before
with some smaller devices and I did not have much success. Now I have a
generator with a rather large sphere. A student of mine told me that it
works better when one has hair jelly on his/her hair. Is it true? How
about the length of time a person needs to wait in order to get discharged.

The best success I've had with a Van der Graf is when I used a thick
sheet of foam rubber as an insulator. Also, it helps to ground the base of
the Van der Graf
