HI,

While it may not be quite as impressive as a tesla coil or a Jacob's ladder, my youngest daughter years ago made it as far as her regional science fair with her project of what materials around the house make the best battery.

35mm plastic film containers were used as cells. Materials for the electrodes were whatever we found around the house, aluminum pop rivets, galvanized nails, copper house wire, steel wire, whatever.

For the electrolyte, we had plain water, vinegar, lemon juice, salt water, Pepsi, Coca Cola, coffee, again, whatever.

All data was compiled on an Excel spreadsheet. The best battery for her...... copper, zinc and Pepsi. If I remember correctly it showed 1.04 volts in a 35mm film container. We never thought about testing it after the Pepsi went flat though. It could have made an interesting comparison.Very Happy

Whatever you choose though, good luck!

Bob

news flash...i'll need two projects...one of which is already nearing completion.... Magnetic levitation....need to sort out some kinks and to refine the looks...as soon as I'm done, I'll post a link to some photos...I need something Gob Smacking so....I think a jacob's ladder will be the second choice...a singing and talking one would be cool....but no time for voice modulation...
