The title might have got your attention eh? 
Well with all the diy co2's goin about, back in the day i played paintball have my own gun, yada yada yada. it ran on co2 gas, ive still got the canister, as i dont play anymore gonna get a mate to go down the paintball site who does to get the canister filled,(used to be free) The canisters got a valve on it to allow the gas to flow or stop, so figured its flow is controllable, potential free source of co2.
I do realise the pressure from the canisters gonna be epic compared to a diy system, but ive read about people using fire extinguishers as a co2 source, so should less pressurised than a extinguisher meaning it should be less dangerous.
Got any insight?
