Show your co-workers you take rubber band fights seriously when you come to work fully strapped with this new Rubber Band Machine Gun ($85). Designed and built by Alex Shpetniy, the Rubber Band Machine Gun is a fully automatic Gatling gun ready to rain down 672 shots of rubber bands (that’s over a pound of rubber) on anyone that stands in your path. Range is about 26 feet, while the firing speed is an impressive 14 shots per second. As for its construction, the Rubber Band Machine Gun’s body and 16 barrels are crafted from birch plywood cut out on a CNC machine, while operation is performed with a single trigger pull and carried out by a small electric engine powered by 5 AA batteries. Your co-workers and their inferior rubber band shooters don’t stand a chance.
