★Easy Operation: simply put the engine on a mug of hot coffee and give the flywheel a gentle push, it'll start to work. If using boiled water the whole process will last for 20 to 40 minutes. ★Very Affordable with Good Quality: unlike most of the Stirling engines, it's mainly constructed by ABS plastics (except for some essential parts), but it works AMAZINGLY. In our fatigue test, it rotated continuously for 5 days with no wear-out! It's actually of fine craftsmanship, lightweight and portable. A fantastic desktop/physics/mechanics toy for everybody, especially for teens. DjuiinoStar stands behind its products, buy with confidence! ★A Greate Engine: Great effort was made to make it simple, stable and robust: use hardened power piston(less friction & unbreakable); a stainless steel string as connecting rod between the flywheel and power piston(less friction); two little magnets at the power piston and displacer interacts with each other as connecting rod (minimize the mechanical friction); the integrally-formed clear base strengthens the stability to some extent. ★A Novelty for Everyone: When having friends at home, it'll absolutely be an eye catcher; kids will be excited. It's also a great entertainment for people in the office, definitely an innovative desk piece totally amazing your peers. ★Wide applications: it'll be a remarkable gift for anyone interested in science. A great conversation piece that could be used as teaching tool on demonstrating mechanics/physics knowledge. Use it as a Coffee Timer: put it on your coffee mug, when it slows down, you know your coffee is ready to drink:-) Cool!
