ok since I work at a haunted attraction I will give you the secret. This room is usually called a vortex. The platform that you walk on is perfectly straight and leveled. While the tunnel 'vortex' spins around it creates the illusion that your spinning out of control and having to use the rail for guidance long story short its an illusion
it looks like the walls move??? What are you talking about the walls are a moving tunnel that spin around constantly giving the illusion that your spinning!!
ive been there and its hard as fuck to walk straight.. your mind thinks your moving but its just the walls.. so your mind tries to cope with the surrounding...
those things suck.. they have one in my local theme park (kennywood) and it doesnt really do anything btw the ride is noahs ark if you want to search it
