Homemade H2O Gun - the Instrument of Justice

I just finished construction on an air-pressure homemade (APH) water gun, from a design posted on the internet by water warrior enthusiasts, who boast of its superior power - greater than the infamous SuperSoaker CPS 2000.

This obsession for a more powerful water gun was spurred on by my preparations for attending Youth Camp in a couple weeks, where water skirmishes occur daily and the Great War happens on a Thursday - 300 kids against 30 staff (and I'm on staff!).

To explain the design (see picture), water from a resevoir is drawn in the lower right barb through the first one-way 'check' valve by pulling out the plunger along the bottom, then pushed up through the second check valve when the plunger is pushed in. The two check valves are integral to this design and the basis of many SuperSoakers.

The water enters the black pressure chambers on top with subsequent pumps and pressure builds. When ready, the ball-valve at top left is opened and pressurized water jets out the final nozzel at the end of the pipe.

Next is field testing! If web claims are correct, it may prove to be the most powerful gun on the battlefield!
