Is it a better mousetrap? Probably not. But it's pretty dang cool, and any hack that calls for a solenoid and a bucket as its main ingredients is alright in our book. The mousetrap is triggered by infrared emitter / detector pairs, with the enclosure holding the electronics standing right over the bait. When the mouse (or other hapless victim) interrupts one of the IR pairs, the electromagnet releases the bucket and the mouse is trapped. We're pretty convinced this is an optimal situation for the mouse, since he gets fed, doesn't get his neck snapped, and ends up at a rave when it's all over -- peep the video after the break to see what we mean.
