Balloon Bazooka ™ - The Ultimate Water Balloon Launcher
 

http://balloonbazooka.com/index.html

Our Magnum Model is really big... For guys and gals who want to launch a balloons out of sight... Would you believe? Over 500ft... You've got to see our videos... This model has a huge air tank, a 6ft barrel, more pressure and a huge valve... You are going to need a compressor to fill this tank and launch these balloons... We recommend using good quality fresh latex balloons for this one, not the old balloons laying around the garage the last couple of years - they probably won't hold together. Talk about FUN! This Ultimate Balloon Launcher with its six foot barrel will launch over two dozen balloons at once towards the target with less distance...but be careful the Balloon Bazooka ™ packs a big punch, so make sure the balloon launcher is on firm ground.

Specs: 4 liter steel tank, 1 1/2" valves, 150psi max, 6-foot barrel, 20 lbs.

I wish they'd pick up the broken balloons. :(

I'll stick to my $25 home-made potato gun that you very much

My freshman year dorm is at lat/lon 40.441268 -79.939073 on Google Earth. It's an H-shaped building, and the crossbar has stairs going down the back. I had one of those 3-man slingshots, and two people could stand at the top of the stairs while the third would pull the pocket with a water balloon while walking backwards down the stairs. We managed to get it to the road once or twice. Not quite 500 feet, put pretty fun.

Holy nuts. That is giant. Death by balloon indeed.
