Follow along as we build this awesome air compressor powered water balloon cannon (water balloon launcher). This little weekend project is all about water balloons, or launching them, by making a cannon to fire them that is! We shot water ballon well over 100ft into the air with this thing. Of course you can shoot many other projectiles out of it as well. It's made with sprinkler parts, PVC pipe, and PVC fittings. Schedule 40 or higher. You can use an air compressor or bicycle pump to charge it for portable firing, or leave the air compressor attached. Have fun and be safe!
