This compact steam engine model is a handson educational tool and hobby gift that demonstrates real steam power in miniature. Made from brass, aluminum alloy, and bamboo, it shows mechanical motion and basic steam engine principles through an operating boiler and moving parts. Key benefits Learn by observing real steamdriven motion: the working boiler and swingtype cylinder convert steam pressure into reciprocating motion and flywheel rotation. Clear demonstration of power output: the model can drive small loads and light bulbs, making abstract thermodynamic concepts tangible. Durable, authentic construction: metal components provide precision and longlasting operation while bamboo details add visual contrast. Compact and portable: tabletop size for classroom demonstrations, hobby benches, or desktop display. How it solves common needs Replaces static models with an operational device that illustrates input, conversion, and mechanical output steps. Provides a safescale platform for experiments with boiler capacity, stroke, and load without industrial scale equipment. Offers a visually engaging prop for presentations, science fairs, and handson learning sessions. Main specifications Materials: brass, aluminum alloy, bamboo Boiler diameter: 46 mm; length: 78 mm; capacity: 60 mL Cylinder: swing type; piston stroke: 8 mm; cylinder diameter: 6 mm Flywheel diameter: 20 mm Drive source: boiler steam Product weight: 400 g Product dimensions: 10 x 10 x 8 cm Package dimensions: 15 x 15 x 10 cm; package weight: 450 g; packing: corrugated box Recommended age: 16 and up Practical use scenarios Classroom demonstration: show the relationship between heat, pressure, and mechanical work during physics or engineering lessons. Hobby workshop: a working display for model engineering enthusiasts to study timing, load behavior, and basic maintenance. Science fair or presentation: power a small load or indicator lamp to illustrate steam generation and mechanical conversion. Notes The model uses a small boiler and steam for operation; follow safe handling practices. Recommended for ages 16 and up.
