Fun Experiments with Electricity

Young experimenters can build a toothbrush robot, tap out Morse code on a homemade telegraph, and generate a small lightning storm of their own. Each project relies on everyday materials and is laid out in clear, follow-along stages. Along the way, the book explains the scientific principle behind every activity, so the results are as educational as they are entertaining.

The activities are designed to be quick to set up and impressive to perform, making them easy to share with a rapt audience of friends and relatives. Watching a motor-driven gadget wobble to life, a light blink on command, or a spark leap across a gap shows how electrical energy turns into motion, sound and light.
