501-9 Electroscope
The perfect way to explore electrostatic principles without outside interference! Great for small children; the unit contains no glass or easily broken parts. A brass ball sits atop a plastic cap, from which very fine copper wires attached to electrostatic balls are suspended. The entire unit is sealed in a clear plastic cylinder that shields air currents.
