Meet Noah. Noah is Ms Katie's grandson, my nephew and 15 year old inventor extraordinaire! We got to witness an exhibition of his latest project - a compressed air powered water balloon canon!
The parts list includes PVC pipe, a 24 volt sprinkler valve, three 9 volt batteries, wiring from an overtired weed eater, a switch from somewhere, an air tank with his dad's air compressor close at hand, duct tape in all the appropriate places and G'pa Al's old golf bag cart to haul it around and adjust the aim.
It was pretty impressive. First a water bottle cut in half, secured with twine to the canon was plunged to the bottom of the PVC pipe tube. The purpose - to create a seal and hold one or more water balloons. Next, water balloons were loaded, aim checked, air tank filled and the area cleared of innocent bystanders. Then 3, 2, 1..FIRE, the switch thrown, a loud WHUMP and the balloons launched!
The red and orange balloons were the easiest to see as they flew over the tree in the middle of the yard, crashing on the driveway across the cul-de-sac, narrowly missing the parked car and of course the older brother trying to get hit!
All watching decided that G'pa Al would be proud!!
Hey, all you reunion cousins, look out!! This is no marshmellow shooter!
