I would like to make my own Claustrophobia effect, I know so many haunts use them but I hear alot of customers walking out of the haunts talking about that room with the black walls that squeezed you to deathr. As far as I can see it is just made of vinyl fabric and a blower.
I would think the vinyl would be attached to backing- plywood maybe, the blower in-take and a vent so it doesnt just explode.
does this sound right? Has anyone esle made one before or know how to?
