A simple, homemade Van de Graff Generator.

Wednesday, October 24th, 2007

Create your own simple homemade Van de Graaff generator.

This project will show you how to build a device that can generate 12,000 volts from an empty soda can and a rubber band. This is capable of drawing 1/2 inch sparks from the soda can to my finger. The spark is harmless, and similar to the jolt you get from a doorknob after scuffing your feet on the carpet.

To build the toy, you need:

* An empty soda can
* A small nail
* A rubber band, 1/4 inch by 3 or 4 inches
* A 5×20 millimeter GMA-Type electrical fuse (such as Radio Shack #270-1062)
* A small DC motor (such as Radio Shack #273-223)
* A battery clip (Radio Shack #270-324)
* A battery holder (Radio Shack #270-382)
* A styrofoam cup (a paper cup will also work)
* A hot glue gun (or regular glue if you don’t mind waiting)
* Two 6 inch long stranded electrical wires (such as from an extension cord)
* Two pieces of 3/4 inch PVC plumbing pipe, each about 2 or 3 inches long
* One 3/4 inch PVC coupler
* One 3/4 inch PVC T connector
* Some electrical tape
* A block of wood
