Stirling engine motor model with glass tube and glass alcohol lamp for direct observation of piston movement. Designed for handson learning, classroom demonstration, and hobby displays. Key benefits Visible mechanics: Transparent glass tube and alcohol lamp let users observe piston motion and wheel rotation as the engine runs, making thermodynamic principles easier to understand. Stable operation: Four anti skid pads on the base keep the model steady during use, reducing vibration and slippage. Easy to run: Simple fuel and start procedure lets users get the engine moving quickly without complex setup. Educational and versatile: Suited for science projects, classroom demonstrations, and physical model learning activities. Main features Materials: Glass tube and glass alcohol lamp for clear visualization of internal motion. Fuel recommendation: Use 95 percent alcohol in the alcohol inflamer for results. Start procedure: Add fuel to the alcohol lamp, light it, and let the lamp heat the cylinder for about 60 to 120 seconds. After the cylinder is heated, gently nudge the wheel to start rotation. Stability: Four anti skid pads on the bottom provide a secure, level base for consistent performance. Practical use scenarios Classroom demonstration: Show students how heat energy is converted to mechanical motion by running the model during a physics or thermodynamics lesson. Science fair or project kit: Use as a handson exhibit to explain engine cycles and basic mechanical principles in student projects. Home STEM activity: Provide an engaging demonstration for children and hobbyists interested in mechanics and heat engines, with adult supervision for safe fuel handling. What it helps you teach or demonstrate The relationship between heat input and piston movement Basic principles of Stirling engine operation and energy conversion Mechanical linkage motion and rotational inertia in a small, observable model Safety and use notes Use recommended fuel only and follow basic safety precautions when handling an open flame. Allow the engine to cool before touching or storing. Supervise younger users during operation. This Stirling engine motor model offers clear visual feedback, simple operation, and a stable platform for teaching and demonstration purposes without complex assembly.
