My outdoor tap supplies about 100-105psi so I use that to fill a old air compressor tank to that pressure and then use it as a water gun! :)

Never do that. It will rust out and explode. By the way, I have the same water pressure.

sounds bloody awesome, would not want a 100 psi pipe blowing underneath my house though .
