Low Temperature Difference Stirling Engine Model Educational Toy for Students

This educational Stirling engine model operates on low temperature differences, demonstrating the conversion of heat into visible mechanical motion. It illustrates the Stirling cycle, helping students understand thermal expansion, pressure changes, and motion transfer. The engine is constructed with a metal body and aluminum alloy base, providing stability and a clean display. It requires no electricity or assembly, making it easy to operate for repeated demonstrations. Suitable for students aged 7 to 14, it encourages curiosity and hands-on learning.
