Sounds like fun. But just how many capacitors would you need to make a
metal former? Assume the metal is thicker than tin-foil so it at least
holds its shape when you pick it up. Or to put it another way, say you've
got two hundred photoflash capacitors, how big a coil can they drive to get
reasonably thick metal to bend this way?
(I have collected a handful of these, and was considering making a Marx
generator. Just another idea for the OP.)
