Vac Suit Rocket

I've just finished illustrating a trap for an upcoming Stars Without Number module, TransMat Treason.

The setup is very simple. A door that's obviously been left slightly ajar, and behind it, an empty vac suit rigged up to blow the contents of its o2 tanks when someone disturbs the door. There are a few fun little tells you can throw in; I usually mention a soft, blinking purple light from behind the door, which turns out to be a pulsating rescue beacon on the shoulder of the suit inside. 

The module is set on a derelict cargo vessel with no functioning artificial gravity. Needless to say, the suit goes careening wildly, taking whoever opened the door along with it.
