Where'd you find the zinc wire? I can't find it anywhere.

Try using a "hot dipped" galvanized nail. The "hot dip" method of galvanizing nails gives a thicker surface of zinc (compared to the "electro" galvanized nails.)

Those really old batteries; not 'heavy duty' or 'alkaline', but something like 'standard duty'. These are usually carbon zinc, and you can tear them apart for zinc

it is iron wire, it has a zinc coating for making it sotronger i think, and you find it in supermarkets or diy shops, even small ones like near where i live ;)
