Gakken Otona no Kagaku Adult Science Stirling Engine Assembly Type Kit JAPAN DescriptionCondition: NEW
The Stirling engine was invented by Robert Stirling of Scotland in 1816, and is a clean external combustion engine that does not emit exhaust gas by utilizing the expansion and contraction of air. By assembling and moving this kit, you can understand the basics of thermodynamics. You can experiment with cars, generators, and electric fans.
An alcohol lamp and a test tube were used for the experiment. By switching ON / OFF of the three levers, it is possible to perform three things: \"experiment to move the wheel to run the car\", \"experiment to turn on the lamp of the generator\", and \"experiment to turn the propeller\". It takes about 3 hours to assemble the kit and no special tools are required. You can understand the basics of thermodynamics by assembling and moving it yourself, so you can enjoy the experiment while learning with your child as well as alone.
The fuel alcohol used for the experiment is purchased separately.Payment
