Can anybody here explain how a Zamperla Demolition Derby ride works? From my understanding there are two turn tables which spin in opposite directions and the cars, which are free to spin in their own independent circles, are transferred from one turn table to another. It's the "hand off" between turn tables that specifically interests me. How do they do it? This ride system is used at the Disney studios park in Paris as Cars Race Rally. A new twist on the design is being built at California Adventure as Mater's Junkyard.
