Description: A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Filling moderate water into the boiler and burnning the alcohol lamps. When the water become boiling, the vapour in the boiler will work as a medium to run the pistons and flywheel. The Hotter the boiler gets, the faster the flywheel goes. Vary interesting! Great for cultivating children's interest in physics, more intuitive and easy to understand how heat engergy is converted into mechanical work.
