Made in Japan, Gakken Otona no Kagaku is a unique mini V-twin steam engine for both educational and tremendous fun. It’s a self-assembly engineering kit, you can learn how the engine harness the power of steam to run that V-engine, something that you build with your own hands. Even though this set comes with every part that you need, some tools, fuel, and lighter are still required. Use a syringe to put water in the tank with capacity of 30cc, then light the alcohol to burn the light. Watch as the heat delivers a maximum output of 2,000 rotations. And just for fun, connect this engine to a toy vehicle with a pulley to make it move. [Buy It Here]
