Stirling Engine Model Kit Educational Physics Demonstration Desktop Heat Engine Brass Metal Construction Science Experiment Toy for Students Teachers

This Stirling engine model kit demonstrates thermodynamic principles through a working heat engine powered by temperature differentials. Crafted from precision-machined brass and stainless steel components, it operates on hot water, coffee, or any heat source above ambient temperature. The transparent cylinder and piston assembly allows clear observation of the power cycle. Ideal for physics classrooms, engineering students, science enthusiasts, and desktop display. Includes all parts for assembly with detailed instructions. No batteries or electricity required — runs purely on thermal energy conversion. Compact size fits on any desk or shelf.
