I posted a few weeks ago about how people were leaving empty nitrous cylinders lying around and wondering if they could be reused for something.
Someone left two of them in the gutter of my house last night, so I grabbed them to get a better look at them.
They are heavy steel. The end caps look like they're 1/4" thick. The label on the tanks say they are rated 120 bar working pressure (1740 psi). That's a lot of pressure!
