Built by a bloke called Jake Easton, the trap is housed in a beautifully designed, shiny, aluminum case. It works using a combination of complex series of solenoids, electronic control circuitry and a heavy-duty pneumatic actuator. The 40 to 60 PSI of compressed air can deliver a death blow of 102 pounds to the pesky rodent. But is it as much fun as using a meat tenderizer? Probably not.
