Water guns are one of those toys you never quite seem to grow out of, and with innovations like this RPG-7 Bottle Launcher it’s going to be a long time before we ever get sick of them.
Essentially an RPG for bottle launchers, this thing looks like an absolute best to use. For those of you not familiar with an RPG-7, it is essentially a rocket propelled grenade launcher. The contraption was designed by Japan’s Marudai, and it fires bottle rockets far enough to ensure that you will be winning every water fight that goes down. [Via]
