No, I'm not talking about a movie :-) I'm actually talking about a room here people tend to refer to as "The Panic Room".
Should there be any fire inside that room, the door automaticaly seals the compartiment, and then some machines suck all the air in the room (no air -> no oxigen -> nofire).
Now... there's a guy working in that room...
I can only begin to imagine the things that guy would be willing to do to put up a fire in there... :-)
