I'm currently building an electroscope for a physics lab, and it's basically set up to be inside a glass jar, with two pieces of aluminum foil attached to a wire inside. The two pieces of foil move when charged objects come near, and it works well most of the time.
However, when there's a lot of charge brought near the electroscope, the leaves tend to flare out in several directions and sort of twist as well. I've tried making a small loop with the wire to control movement, but the same problem still occurs.
Does anyone have any suggestions on how I could modify the wire or even the leaves to solve this problem?
