Electric Generator

Build your own electric vehicles and machines, and then power them up with a hand-crank generator. Assemble 11 models including a racecar, “flying” car, radar car, satellite car, propeller airplane, drilling car, bulldozer, space station, well-digging machine, and portable camping torch. Experiment with your electric generator and your models: Alter the crank-time and the crank-frequency and see how these variables affect the performance of your cars and machines. Compete with your friends to see whose hand-crank powered car runs fastest! The hand-crank generator doubles as a hand-powered LED flashlight! The 36-page color instruction book included in this kit illustrates the step-by-step assembly of each model and related principles so that children learn through playing. The 122 building pieces included in this set are compatible with those in all Thames Kosmos Construction Series kits, Physics Series kits, Wind Power, and Hydropower kits.
