Twist Ride

A basic spinning ride you would see at a fair or an amusement park. Quite simply spin the top wheel, and watch the cars go.

The model works because each piece with cars is glued to a gear underneath. The top plate spins, causing the cars to spin. The base has a static gear, that meshes with the gear attached to the cars.
