I've tried 9v, 6v, multiple lower voltage cells (series and parallel)- only way I get it to work is with jumper cables. *sighs* Some things just don't work around me, I swear.

Since you were the first one... :P

The rusty stuff got binned. I came to the same conclusion Blast wrote out- rust has lower potential energy. I'm talking about slathering FRESH 0000 steel wool with pj like one might cotton wool, as a vapor and air proof layer to prevent oxidation, and give it that little something extra.

Yeah, this is definitely the way to teach...

I'm really starting to understand Blast's pattern of thought, and that scares the heck out of me!
