+ | ===== Notes ===== | ||
+ | The Van de Graaff generator vibrates significantly while running, so a piece of tape may be necessary to prevent the windmill from falling off of the generator. | ||
- | ===== Notes ===== | + | The electrostatic windmill needs a high voltage to start turning, so move the grounding 'wand' far away from the head of the generator. |
