Electroscopes are a simple instrument that kids can use to give evidence for static charges. Kids can build their own... once built they can last for years. They have both a qualitative and a quantitive aspect. Electroscopes are a great way to begin to understand induction which is one of the more challenging concepts involved with electrostatics.
