Show sparks flying. Make hair stand on end. Illustrate how positive and negative ions attract or repel and more. It’s easy with our new low-cost Van de Graaff generator. This hand-crank model can develop voltage of up to 200 kV and produce a spark up to 3.2 inches long. 25" high with a 10" dome, it includes a variety of accessories including a 16" discharge electrode, electric plume, and the electric whirl. Best of all, it’s less than half the cost of a traditional Van de Graaff generator, so you’ll be able to conduct spectacular electrostatic experiments without breaking your budget.
