2 Cylinder Hot Air Stirling Engine, Stirling Engine Model Steam Engine Kit Balance Stirling Engine Kit Physical Model for Educational

• PHYSICAL EXPERIMENTAL MODEL: Glass tube and glass alcohol lamp facilitate direct observation of piston movement, the heat from high-grade alcohol, the engine will run madly and create the electricity, the power will go through the wire and drive the LED lighting
• MULTIPURPOSE: The 2 cylinder hot air stirling engine has a wide range of applications, such as gifts for children's science projects, physical machine learning, teacher demonstration props in the classroom, friends, family, parents, children's birthday gifts
• SIMPLE TO OPERATE: The stirling engine model, fill the alcohol lamp with 95% alcohol (we recommend this fuel) and light it. Let the light burn on the cylinder at the round end for about 60‑120 seconds, then push the wheel lightly and it will work like a charm
• ANTI SKID: The stirling engine motor model are 4 anti skid pads at the bottom of the model machine to ensure steady operate, elegant gift wrap, low noise, low pollution, low running cost, the overall fine grinding, feel smooth, very metallic and modern technology
• WIDE APPLICATIONS: The two cylinder stirling engine model has a wide range of applications, can be used as a prop for children's science projects, physics mechanics learning, and teacher's classroom demonstrations
