Game on stress resistance that keeps everyone on edge

The idea is simple: participants stand at a door with a key, while a masked man, playing the role of a pretend killer, slowly creeps up behind them. The task is to calmly take the key, open the door, run inside, and lock it just in time.

Most participants fail the challenge. Panic kicks in before logic, their hands shake, the keys fall out, and the door remains open.
