DigiWiz Hand Crank Generator
Ages 8 Years +
The DigiWiz Hand Crank Generator works through the physical knowledge of gear transmission and energy conversion. Turn the hand shank, accelerating the smaller gear through the bigger gear’s drive. Then through the shaft, use the bigger gear to make the smaller gear to accelerate for the second time. The DC generated by the running generator will light up a little bub. This work demonstrates the process of mechanic energy-electric energy-luminous energy.
