A Ski Lift Carries Mice Out of a Chicken Coop and Releases Them Downhill

Super Valid Designs built a semi-automated ski lift to live-catch mice in a chicken coop and carry them down a hill. Each gondola doubles as a mousetrap: bait lures a mouse onto a ceiling trapdoor, which drops it into the car.

The occupied gondola then travels downhill, where another trapdoor opens over a brush pile to release the mouse. The lift was assembled largely from wood and parts on hand and was made to transport and release the mice automatically.
