Generate up to 200,000 volts of safe electricity to experiment with electric fields and electric forces! 

This deluxe table-top Van de Graaff generator kit 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 with low-amperage electrical charge immediately. Explore concepts related to ionization, electrons, positive and negative charges, and so much more!

The detailed operating manual that comes with this hands-on Van De Graaff Generator Kit explains:

  • electric fields, 
  • how the Van de Graaff generator (VDG) works, 
  • how to use and maintain it for maximum performance, 
  • and several experiments - including the classic hair-raising experiment and 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. Use this Van De Graaff Generator kit to create a scientific spectacle at home or in a classroom!

Robert J. Van de Graaff, a professor at MIT, invented this generator in the 1930s. A rubber belt inside it generates static electricity, which spreads to the metal dome/metal sphere on top. Checkout now and order a replacement belt to ensure that you never miss a moment of hair-raising static electricity fun!
