How does this air tank/compressor work?
So I have a 15lb. air tank which has three spiky things that air comes out of or goes into and a pressure gague and a release lever. I need to make it into an air compressor to fire a cannon (theatre thing). I don’t have any idea how to power this. There are no plugs or cords or anything!
Help, I’m feeling like an idiot.
Actually, this is for shooting fake blood across a stage.
