That’s brilliant. I must make one for my beer.

It’s too bad he forgot that old fire extinguishers are primarily lead soldered copper sheet. If you do this make sure yours is stainless.

Avrpunk is right. Almost all solder except the new rhos garbage has at least small amounts of lead and the soldered copper fire extinguishers are no exception.

Old copper fire extinguishers might very well have lead in them.

As to whether or not drinking a few cups of beer will cause any harm is another matter. Getting your hands on a copper fire extinguisher would be a fairly expensive proposition as well.

Finally somebody is doing somthing useful with fire extinguishers!

Way to go Ben!

The extinguishers are indeed entirely stainless. They were sort of dirty inside because they’d been sitting outside at a metal yard for who knows how long.

Most of the extinguishers do not have a large enough top to actually reach in and clean them out, so if you’re thinking of doing this yourself, look for the ones with a large cap…

Copper water pipes can handle 100psi, not bad. Seen some plumbing pressure tests done. It’s thirst extinguisher.

Hahah copper extinguishers. Are you talking about the old Soda-Acid ones? I don’t know where commenters get this stuff sometimes.

Think that fire extinguisher container (empty) used to be a container of toxic chemicals for extinguishing fire. If you recycle the scrap into food container, that would mean something negative to your health. You did what is good for the environment, I salute! It would be good to have the container in the garden for watering plants.
