A ride found at amusement park
s, and county fair
s. You lean against one of the not-quite-vertical wall segments inside a round room. The ride operator, in the center, sits in a booth and plays loud music.
Here's where the fun begins. The room begins spinning around the center booth. As the room spins faster and faster, the wall segment behind you spins outward -- and upward -- lifting you off the floor.
Then after a minute or two, the operator presses a button and the room slowly stops spinning. Everyone's piece of wall slides back down to the floor, and you all walk out holding onto the handrails for balance.
Kind of like the spin cycle on a washing machine.
