This week in class we’re making an electroscope. All you need for this is a balloon, paper clip, a clear drinking glass, cardboard, tape, tin foil, and felt or your hair. The electroscope comes together nicely after that and then you could rub the balloon against the felt or your hair. If you move the side you rubbed near the tin foil you hung up from the paper clip, you will see it move. I think this is because of the static that “collected” when you rubbed on the balloon.
