Van de Graaff Generator

Our Van De Graaff is a great crowd-pleaser  This Van de Graaff generator is capable of generating 600 kV and is one of the best I have ever seen of this size. It work very well on humid and damp rainy days. You will want the smaller discharge sphere and discharge stick. Watch out around computers,  smart phones, pace makers, and other electronic devices.
