No it isn't, if your willing to cheat:  go buy a dozen of the cheapest
carbon-zinc batteries you can find, and take a hacksaw to the casing.
The casing you find inside is zinc.  It's been many years since I've
taken this apart as a kid, but I remember the operation is a mess.  I
don't recall any hazard, but I used kitchen gloves to handle the stuff
just in case.
