You're in a pitch black room about 15 feet wide, and 100 feet long.
At the end of the room, there are 10 keys laying on 10 different pedestals.
Each key has a faint smell that's very hard to distinguish from the other keys.
Here's the catch...
You gotta take the key that has the same smell as a decomposing sperm whale.
And you never smelled a dead whale...
You have 3 minutes to make your decision...
The exit is hidden with no way to find it without turning on the lights...
You must get the correct key and put it into the light switch to activate it...
the wrong key inserted will trigger an explosion to occur...
3 minutes pass before you make the decision, and the pedestals will open up, and release a toxic gas.
The clock is ticking.
