OK, had an idea for a competitive scenario of some kind, thought I'd put it up here, see if anyone was interested.

The idea is as follows: two women are placed naked inside two glass rooms, adjacent to each other. The contents of the rooms will be left up to the writer, but they must each have a device at the top that will suck out all the air from the room, creating a vacuum. The devices activate at the same time, and the two women must either find a way to escape the room, or complete a specific task in order to be let out. However, only one will be able to escape - once she does, the other woman is permanently trapped, and will eventually die from lack of air to breathe.

Thoughts?
