I have to make a van de graaff generator for my physics class.
The Attempt at a Solution
I put it together and it doesn't work at all. Please help. Is the reason it isn't working is that i don't have a glass tube or something else?
We build one using pvc pipe, thin rubber band, small dc motor, and 2 plastic pulleys, brush wire, and a can. I made it based on this tutorial http://scitoys.com/scitoys/scitoys/electro/electro6.html The only difference is that mine uses a plastic pulley where the glass tube should go.
