This book is the content very useful.This is the best book children to learn about electricity. I liked it so are explained clearly. Once upon a time, people did not know why lightning is falling. So it was believed to be the work of God. Benjamin Franklin also appeared in this book. He is a man who proved that lightning is caused by nature. They will not be able to live human electricity runs out in this day and age. The method that electric experience is made simply is written on the last of a book. Please try it.
