Video: Need a weapon? Grab some magnets and some nails and you got yourself a hell of an arrow launcher. The magnets push out the nail darts so fast that it’s basically a mini crossbow mixed with a nailgun, no batteries necessary. Magnetic Games said that in order to get this powerful shot, the arrow and the launcher have to have the same polarity.
Digg recently found the video and it’s actually pretty crazy to see how powerful the little weapon is.
