I was flipping through my copy of Walt Noon's Secrets of Building Electrostatic Lightning Bolt Generators (1992) and came across this photo, captioned: "The author's hair is usually flat and combed somewhat back. After a few minutes connected to a running Van de Graaff generator, and he's ready for a punk-rock concert!"
Walt is a good magician. Check out his videos.
