It's hard to find one, probably in construction hardwares, they usually call it copper tubing. I made another design of the water battery by only using copper wire and nails. My new version is more efficient, more powerful and uses mor common materials.

As long you are using carbon-zink or alkaline it is totaly safe. I might make a instructable for opening a battery properly. I opened it without breaking. lol

so, what kind of battery should we get the rod from?

carbon-zinc batteries should do nicely

Can you use the rods from an alkaline battery, though? Carbon-zinc batteries seem to be hard to find :\
