It's really interesting and imaginative toyThis is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air (or helium or hydrogen) as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and strong power. As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs. Aerodynamics are rich in knowledge of physics, single cylinder combustion engine. Engine principle is intuitive, educational toys, teaching experimental equipment can effectively cultivate children's interest in learning can also be used for classroom teaching, more intuitive and easy to understand.
EASY OPERATION & LONG LASTING----Fill the alcohol burner with your 95% alcohol (we recommend this fuel) and light it. Let the light burn the round ended cylinder for about 60-120 seconds, then give the wheel a gently push, it will run like a charm.
