This room was quite a project (big by my standards, anyways). The point of this room (pun intended) was to get the kids into a closed room, then have spikes emerge from the ceiling and have the ceiling start to lower downward. It required a sturdy 4' x 7' x 10' frame, thirteen carved foam-cast skulls, 26 flexible foam spikes and a false ceiling. I almost gave up on the project because, of all things, I couldn't find a good way to make the spikes. Eventually, I figured out a way that worked. The finished room was a big hit and really creapy. Well worth the effort.
