Hot Mini Model, Education Toy Electricity Power, Electricity Colorful LED (16 x 7 x 8cm)

Description: Physical Science DIY Kits - Flywheel Engine Model with colorful LED, physical motor heat power electricity external combustion engine model kits - to internal combustion engine: the burning alcohol lamp provides heat power to make the expansion of gas inside, then the gas internal power increasing and working strongly to the flywheel. With the help of the flywheels, heat energy will convert into mechanical work, then into electric energy Great Educational Toy - Classroom or experimental teaching aids, cultivate children'sinterest in physics, more intuitive and easy to understand Great gift for your friends or families. A engine is a heat engine that operated by cyclic compression and expansion of air or other gas (the working fluid) at different temperatures, such that there will conversion of heat energy to mechanical work. Specification: Material: Metal, and Glass Size(LxWxH): Approx. 16 x 7 x 8 cm / 6.3 x 2.76 x 3.15 inch Package Includes: 1 Set Engine Model (with Colorful LED)
