Make sure you use a penny dated before about 1984... later pennies are
copper-plated zinc, not solid copper!
To see for yourself, take a post-1984 penny, and make a shallow cut in
the edge with a file or hacksaw. The silver-colored zinc will clearly
show. Now drop the penny in some hydrochloric acid (AKA muriatic acid,
as used in swimming pools) for a week or so (until bubbles stop
forming at the cut). Remove with tongs, rinse well, and you'll have a
nice, hollow penny made out of copper foil.
Do I know how to have fun, or what? :-)
