Color: Silver Key benefits Clear demonstration of piston motion thanks to a glass tube and glass lamp that make internal movement easy to observe. Simple setup and operation in a few steps, suitable for classroom demonstrations, workshops, and hobbyist use. Low noise operation and low operating cost for extended display and learning sessions. Stable performance supported by a wooden base with four antislip pads to prevent tipping and vibration. Visual feedback with a large flywheel that smooths motion and an LED bead that highlights operational effects. Features and specifications Function: Physical experiment model driven by hot air to show piston and flywheel dynamics. Materials: Transparent glass tube and glass lamp for clear viewing, wooden base for stable support, metal flywheel, and builtin LED bead for visual indication. Color: Silver finish for a clean, neutral appearance. Performance: Designed for quiet, lowcost operation with visible, smooth piston and flywheel movement. Stability: Four pads on the bottom of the wooden base increase grip and reduce movement during operation. How it solves common needs Makes thermodynamic and mechanical principles tangible by converting hot air input into visible piston motion, aiding comprehension for learners. Reduces distraction with a low noise profile while keeping running costs low for repeated demonstrations. Improves demonstration quality with a large flywheel that stabilizes rotation and an LED bead that draws attention to motion. Practical use scenarios Classroom demonstration: Show basic engine principles and piston motion during physics or engineering lessons. Science fair or workshop: Provide a clear, handson exhibit that lets viewers see energy conversion and mechanical movement. Home study or hobby bench: Use as a desktop model to explore thermodynamics and mechanical motion in a compact, easy to operate setup. What to expect in use Simple preparation and a straightforward procedure get the model running in a few steps. Observe smooth piston travel and flywheel rotation through the transparent glass components. Stable positioning on the wooden base ensures consistent demonstration without frequent adjustments. This model is intended as a physical experiment tool for visualizing piston and flywheel dynamics.
