Build your own models powered by air and water pressure
to learn about the laws of physics.
This unique kit allows you to build two different
airandwaterpowered systems: waterjet propelled cars
and hydropneumo powered engines.
(which simply means air pressure and water pressure)

The hydropneumo system uses a selfcontained airandwater
turbine system as a motor.

Construct 15 models including a truck excavator radar car
tank antique car helicopter motorbike backhoe rocket car
forklift roadster propeller plane grinder and cutting machine. The waterjet propelled cars are a fun outdoor activity
while the selfcontained hydropneumo powered models are
fun both indoors and out.

Compete with your friends to see whose waterjet propelled car
and hydropneumo car goes the fastest!

The 48page color instruction book included in this kit
illustrates the stepbystep assembly of each model and
related principles so that children learn through playing.
The 165 building pieces included in this set are compatible
with those in all Thames & Kosmos Construction Series kits
Physics Series kits Wind Power and Hydropower kits.

Ages 8 and up and includes a 48page Manual.
