Main Features:
- Powered by Hot Water A glass of water, whose temperature is 30 degrees higher than the air temperature, can be a perfect power supply for this engine. The whole device starts working after you push the flywheel clockwise / counter-clockwise.
- Good Tool for Studying Physics The model can greatly arouse children's interest in the conversion of different kinds of energy. It can also lead them to learn more about the application of new energy nowadays.
- Easy Assembly No extra tool is required. You just need to press the little hooks onto the shaft, and put the shaft between the two struts.
- Brilliant Workmanship The little cylinder consists of a glass piston and an acrylic frame, therefore, the resistance between them is very low but the air-tightness is impressive. Additionally, the smooth stainless steel base is unlikely to get rusty.
