For those who’ve always wanted a water balloon launcher, check out the ” Douchenator“. To build one, you’ll need: 1 x 1 1/4″ metal ball valve or solenoid valve, 2 x 3″ to 1 1/4″ reducers, about 4-6 feet of 3″ PVC, 2 x male 1 1/4″ couplers, 1 x 3” endcap, Teflon sealant tape [thread seal tape], 1 x schrader valve, saw, drill, drill bits, PVC cement, and PVC primer. Video after the jump.
The launcher will shoot anything from a golf ball to a tennis ball at extremely high speed and extremely far. For wadding, a tennis ball can works best. For the valve, use a solenoid or metal ball valve at least 1 1/4″ in size
