ABSTRACT:
A toy system that utilizes a vehicle that rides upon a track using a unique propulsion system. The track used by the toy has an external surface upon which the toy rides. The track also defines an internal conduit that extends the length of the track. A primary magnet is provided that is free moving within the internal conduit. The primary magnet is moved by a flow of fluid. The toy that rides along the track contains a secondary magnet. The secondary magnet and the primary magnet attract through the structure of the track, thereby causing the secondary magnet and the toy to move along the exterior surface of the track as the primary magnet travels through the conduit.
