Size: type1 Product overview This classic Stirling engine model is a durable, fully assembled demonstration unit that runs using a simple heat source. Its transparent body and metal construction make the internal motion easy to observe, turning a basic experiment into a clear, handson learning experience. Key benefits Easy to operate: Place the model on of a cup of hot water, give the flywheel a gentle flip, and the engine will begin running on its own. The simple start procedure makes it suitable for young learners and beginners. Clear learning tool: The transparent housing lets users watch the internal parts move, helping to illustrate the Stirling engine thermal cycle and basic mechanical principles in an intuitive way. Durable construction: Critical parts are made from metal for strength and longevity. intensity PC material is used for the transparent body, offering heat resistance and safe handling. Ready to use: The model comes fully assembled, so there is no setup or installation required. Safer operation: The engine runs from a cup of hot water and does not require an alcohol lamp, reducing fire risk during use. What it does Converts heat from a cup of hot water into rotary motion. Demonstrates the Stirling engine cycle and simple mechanical linkage in real time. Serves as a visible science aid for explaining heat, pressure, and motion. Materials and specifications Size: type1 Frame and moving parts: metal for durability Housing: intensity PC plastic, heat resistant and safe to handle Condition: fully assembled How to operate 1. Pour hot water into a heatresistant cup. 2. Place the Stirling engine model on of the cup so the heat source contacts the base. 3. Gently spin the flywheel to start. The engine will continue running driven by the heat difference. Practical applications and use scenarios Classroom demonstration: Use during physics lessons to show heat engines and thermodynamic principles in a visible, repeatable way. Home science project: A compact, safe model for handson experiments that illustrate how heat can be converted to motion. Desk display and conversation piece: A working mechanical model that explains engineering basics while serving as a neat desktop exhibit. What you get A ready to run Stirling engine model, size type1, assembled and ready for immediate use. This model is intended for educational and demonstration purposes to help users explore basic mechanical and thermal principles through direct observation and simple operation.
