Imagine you're a wee mouse going about your business when lo and behold, you see an irresistibly tasty snack of peanut butter. When you approach, suddenly there's a loud noise and you're sucked into a deep, dark hole.

Well, Hacker Gadgets forum user Larry Holm created this DIY mouse trap using a ShopVac and a motion sensor:

“I built a mouse trap using an infrared motion sensor wall switch, an extension cord, a paper towel tube and a mini shop-vac. peanut butter is the bait. The mouse goes in the tube. The sensor senses it and turns on the shop-vac for 3 seconds. And voom, the mouse is inside the shop-vac. The sensor turns off the shop-vac. And it’s ready to catch the next mouse. No re-setting. No mess. No kidding.”

Question is: is it an ethical mouse trap? Link - via MAKE, which has a lively discussion about whether such a trap is ethical.
