The traditional summer water balloon fight just got a little more intense. Fill up a water balloon and load it into this shoulder-mounted water mortar. It uses a spring-loaded mechanism to fire the water balloon. The effective range is anywhere from 15 to 20 feet, and this device is sure to piss off Mom. $40.
I'm all for the 3-man slingshots. Working on a college campus, it's pretty dead during the summer around here. We found we could shoot out of my office door on the 2nd floor and almost nailed our VP as he came out of the President's office halfway across campus.
