I was watching tonight this show on Travel channel "Scariest Halloween Attractions 2008" and it showcased a bunch of Haunted Houses around the nation. I saw this tank with a rattle snake in it. It didn't move or at least it didn't in the shot. Anyways, it gave me an idea. Has anyone done a striking snake prop with pneumatics or know how to do one? I know the Halloween stores have these huge 6-7' snakes this year that it could be done with, but how?
