Build your own models powered by air and water to learn about the laws of physics.
This cool experiment kit includes 15 fully-functional models to make. Using the 44-page illustrated experiment manual to guide you, construct a helicopter with rotating blades, a cool excavator, a heavy-duty motorbike and many more. You can even assemble your own water-jet powered rocket car that zooms along at high speed! Each model is powered by only water pressure and air. An awesome insight into renewable energy and physics.
