A small high voltage generator that will achieve 30,000 to 40,000 volts of “static” electricity. The Mini van De Graaff generator is a complete Van de Graaff system, comprising of high speed motor, dissimilar charging rollers , charge take off combs and a storage ball. The VDG runs from a 12V supply (either and external power supply or from batteries) and is completely safe to use this is because although the output voltages are high, the current this little device can provide is very small. The charge is smaller than you can pick up walking across a carpet on a dry day. But this is enough to get sparks to fly 15-20mm and you can use the Mini Van de Graaff for a number experiments :- Franklin’s bells, Jumping Rice, Electric Wind, ping-pong ball cyclotron. See the resources section for more details. Now available with a Polished Stainless Steel Dome.
The Mini Van De Graaff kit is designed for kids (or adults) to learn about “static” electricity by actually building a working device. This can lean on to discussions about charge separation, contact charging and the tribo-electric scale.
The VDG is easy to construct and to take apart. Various changes to the device can be made to study the effect that changes to the combs and charging rollers make. The kit has been made so that it can be maintained easily, so if after long use your Van De Graaff is showing signs of wear, there is a Van de Graff maintenance kit to restore the Van De Graaff back to its former glory.
