Generate up to 200,000 volts of low-amperage electricity to safely experiment with electric fields and electric forces! This deluxe table-top Van de Graaff generator will consistently produce 5-6" sparks (12" sparks are possible!) and can raise your hair almost instantly! It comes fully assembled and includes a grounded discharge wand to begin experimenting immediately.
The detailed operating manual explains electric fields, how the Van de Graaff generator works, how to use and maintain it for maximum performance, and several experiments, including the classic hair-raising experiment and producing spectacular St. Elmo's fire.
Because the current produced by this Van de Graaff generator is so low, it's safe to play with the hundreds of thousands of volts of electricity it generates! This makes a fun and very memorable scientific demonstration of the difference between voltage and current.
Robert J. Van de Graaff, a professor at MIT, invented this generator in the 1930s. A belt inside it generates static electricity, which spreads to the metal dome on top.
