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.

are you a genius

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

yo i found some battery and there was this white sticky stuff (don't say it) arount the carbon rod so wen i pulled it out the rod broke in half. is this a problem. also i got some on my hand so im wonderin if it will kill me.

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

[xxjackxx]

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 :\
