Create lightning with your Van de Graaff generator. Turn out the lights, and connect the lightning plate to your generator. When the lightning is created and the sparks jump across each gap on the lightning plate, your students will be very impressed. A sensational demonstration your students will long remember. The lightning plate is designed to be hung from our Insulating Stand (AP5990) and should never be used with any voltage source other than a Van de Graaff generator.
