Is there a simple way to "make" static electricity from an AC outlet? Looking for a way to make my hair stand (what is left of it) on its end for an experiment. Thanks for your comments in advance.

I guess I need a portable Van de Graaff generator - is that the only way?

Electrostatic generators can be divided into two categories depending on how the charge is generated:

1. Friction machines use the triboelectric effect (electricity generated by contact or friction)

2. Influence machines use electrostatic induction

http://en.wikipedia.org/wiki/Electrostatic_generator

The favorite electrostatic generator at our Museum of Arts and Sciences is the “Kelvin Water Dropper”. All of our visitors love it. It does not need AC power; only falling water powers it!

BobbyWhy - thanks I have never heard of the KWD! -- Seems like it would be cool to build on a down spout where it rains a lot.....

Windadct, If you intend to build a Kelvin Water Drop Electrostatic Generator, I highly recommend using Bill Beaty's website for you guide. See:
