>That reminds me of my grade seven science fair project. That was a rather
odd Wimshurst machine for making electric sparks jump between two points.
It
involved (among other things) a handcranked vinyl 33 LP record some copper
piping and a Leyden jar (capacitor) made of a glass peanut butter container
with aluminum wrap on the inside and out. It sparked pretty well too.

I never played with stuff like that, but I made an arc lamp with some
washing machine brushes.  Worked really god until the aquarium water got
really nasty so I bypassed it.  (Hint: don't try this at home)
