1. The problem statement, all variables and given/known data

I have to make a van de graaff generator for my physics class.

2. Relevant equations



3. 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?

1. The problem statement, all variables and given/known data

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/e.../electro6.html The only difference is that mine uses a plastic pulley where the glass tube should go.

If that's the only difference, then its probably a good clue. Try using a glass (or maybe nylon) tube. The reason for it not working is rubber and plastic are on the same end of the "triboelectric series".
