How much would it cost for an 8 pound dry chemical fire extinguisher? thats been approved by fire services and all that good stuff
This may not take you to exactly what you need, but you can navigate. I got the link of my 8th grade teacher's website, he still has it from we did this.
I would certaintly think so at the pressure that water would be flowing out and i would think it could even be deadly .DONT TRy IT
