Hi!
Right now, I am trying to make "something" that creates enough static electricity to pick on small molecules with negative charge. So in retrospect, I thought rubbing some fur on the PVC piping might be the best way to start out to learn the concept of static electricity.
So the question, how do I measure what polarity the PVC pipe is charged to and how much it is charged? As I said, the small particle that I am trying to collect has negative charge and I need a way to make sure the charge on the PVC piping is always going to be positive.
