Very fantastic craftsmanship, made with metal alloy The hotter it gets, the faster it goes! A stirling engine is a heat engine that operated by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, so that there is a net conversion of heat energy to mechanical work. Engine principle is intuitive,educational toys,teaching experimental equipment can effectively cultivate children's interest in learning can also be used for classroom teaching,more intuitive and easy to understand. Great gift for your friends or families, or a display on your desk or anywhere!
