I've never seen a more alluring mousetrap than the OneDown Rat Trap. I can only be thankful that I'm not as small as the rats it's supposed to attract. It's so sleek and stylish, I keep forgetting that if it actually serves its purpose, it'll have a dirty rodent inside it.
Designed by Aakash Dewan, the OneDown Rat Trap is certainly an unconventional snare. Taking the shape of a ventricular vase, as soon as the mouse or rat is trapped, the vase tips upright so that it can't escape.
