You should be able to find at least copper and probably zinc wire at your local hardware store. If you can't find the copper wire, you can supposedly use a penny. But I've heard of a lot of people having trouble with this, since there's only a little bit of copper in pennies. As for the zinc, zinc wire is best, but you can also use a galvanized nail. These nails are made with a zinc coating, so they're almost as good as the wire. You can also find strips of zinc in the casing of older D batteries - just make sure you're careful about taking them out.
