That’s a crappy pressure vessel holding 350ml of 80psi air, for about 100J of stored energy. I’m not entirely sure I’d be comfortable with that, especially anywhere with my face in the line of fire it it fails.

Yeah I had something like this for several years. Works really well for cars

I wonder if one of those recently-emerging Chinese electric blowers that sub for canned air would generate enough air volume to sound the horn usefully. Possibly not quickly enough.
