If you thought the Rubberband Machine Gun was bad, think again. This AirSoft Project 2.0 is capable of spitting out up to 1,500 rounds of pain in a single minute, effectively handing over the reign of power in your entire office regardless of your position. Thankfully, this is a 100% D.I.Y. project which means you can’t pick one up from a store and inflict pain upon those whom you hold grudges against. Based on information gleaned from the project page, it costs anywhere between $150 to $250 and up to 10 hours of time before the masterpiece is completed.
