Experiment With Pneumatic-Hydraulic Engines The laws of physics
come to life in this creative construction kit. Build vehicles
powered by air and water as you learn about water and air
proplusion and hydro-pneumo systems that use a self-contained
air-and-water turbine system as a motor. A colorful instruction
book illustrates step-by-step assembly for a truck, excavator,
radar car, tank, antique car, helicopter, motorbike, backhoe,
rocket car, forklift, roadster, propeller plane, grinder, and
cutting machine. Once built you can compete with your friends to
see whose water-jet propelled car and hydro-pneumo car goes the
fastest. This unique kit allows you to build two different air-
and-water-powered systems: water-jet propelled cars and hydro-
pneumo (which simply means air pressure and water pressure)
powered engines. The hydro-pneumo system uses a self-contained
air-and-water turbine system as a motor. The 165 building pieces
included in this set are compatible with those in all Thames and
