Our small Van de Graaff Generator stands less than 20 inches tall, but can produce voltages of up to 200kV and 5cm sparks only seconds after startup, at a great price. Years of manufacturing experience have been incorporated into this design that gives reliable results in all humidity conditions. Large, 21cm polished dome collects large charges, and the transparent column allows users to see the machine's operation. Includes operation manual. 110V
