It's awfully hard to get a picture of a spark. I've tried. If we get the science fair project closer to completion, I will see what I can do.
We got the instructions from Make magazine. It's some pvc pipe, a rubber band, the glass tube from a fuse, a small hobby motor, and the top sphere is actually just an old Coke can. It doesn't charge enough to make your hair stand on end, but it does charge enough that sometimes the sparks are uncomfortable.
