Probably already know the answer but thought I would give this a shot. My theatre is going to be doing Cats. We want to use ground fog for sections of the show. We are in a pretty enclosed space with no ventilation. Any possible suggestions on a way to suck fog out of room?

Was thinking of building an exhaust system with a large shop type floor fan built into a wooden box and running some kind of venting (4 - 6" wide plastic tubing) to 4 or 5 areas over the stage with the fan blowing out a door behind the stage? Any thoughts if this would/could work?
