JUST THOUGHT THIS WAS IMPORTANT TO SHARE
If you take off a jumper that you've had on for a while, you can often hear a crackling sound. If you do it in the dark, you might be able to see sparks (never tried it though).

On the left hand page, I remember this diagram of how a Van de Graaff generator works and there was this girl using one on the bottom left hand side of the page. Her hair was going up and she was smiling.

Meh. Blah. I ramble.
