Disposable lighter valves

I say hook it up to propane lot more power from that.

Yea, you could, but that kindof takes away from the novelty of having a power lighter, then its just a propane fire on a hose, and not really a toy anymore

Then do it good and pressurize a reservoir full of water with air pressure from the top; attach hose + nozzle on bottom and there you go.
People have made water guns working like this.
