ABSTRACT:
A toy vehicle and launcher combination apparatus. The illustrated toy vehicle has a rubber bladder or chamber member that is expanded by water or other liquid under pressing while the vehicle is held on the launcher. The launcher may include a reservoir and pump to provide the water under pressure. When the chamber member is sufficiently expanded, the vehicle is released. A spring gives the vehicle an initial forward thrust; the expanded chamber member contracts to expel the water through a rear outlet nozzle to propel the vehicle forward at a rapid rate.
