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.
