Mini Stirling engine model that demonstrates how heat is converted into mechanical motion in a compact, tabletop kit. Key benefits Clear, hands on demonstration of thermodynamics and external combustion principles, ideal for learning and teaching. Simple operation that lets students and hobbyists see the engine running within seconds. Durable construction with a stainless steel hot cylinder and an elegant zinc alloy bracket for long lasting display. Doubles as an engaging desk ornament or teaching aid that encourages curiosity about physics and mechanics. Features Easy to operate: fill the small fuel bottle with alcohol (not included), ignite the wick, let the flame burn for about 20 seconds, then give the flywheel a gentle push to start continuous motion. External combustion Stirling engine design provides a visible example of converting heat to mechanical work. Hot cylinder made of stainless steel rather than glass for greater durability; zinc alloy bracket adds stability and a refined appearance. Compact, mechanical motion is visible and steady once the engine reaches operating temperature. Practical use scenarios Classroom demonstration: use as a visual aid when teaching basic thermodynamics, heat engines, or energy conversion. Science fair or project model: present a working example of external combustion engine principles in a student project. Desk or display piece: place on an office desk or shelf as an educational conversation piece and kinetic sculpture. What you should know Fuel bottle and alcohol are not included. Operation requires an open flame to heat the wick for about 20 seconds before the engine will run smoothly. Intended as an educational model and display item to demonstrate engine principles rather than as a power source. Materials and performance Hot cylinder: stainless steel. Frame and bracket: zinc alloy. Performance: quick startup after heating, visible flywheel rotation demonstrating conversion of heat into mechanical motion. This compact Stirling engine model provides a reliable, easy to use way to demonstrate fundamental mechanical and thermal principles while serving as an attractive and educational desktop display.
