Because the device is enclosed, it is the perfect way to explore electrostatic principles without outside interference! It is wonderful for small children as the unit contains no glass or parts that can be easily broken. A brass ball sits on top of 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 which shields the balls from air currents. Instructions are provided. 3-7/8" x 3" ; 0.18 lb.
