As a small boy, he sat on goose eggs to see if he could hatch them. He mixed chemicals together and urged another child to drink the concoction, telling him it would make him able to fly. He lasted only three months in school because he asked too many questions. Eventually, he grew into the most prolific inventor in history, claiming nearly 1100 patents in a 60-year career. Tom Edison gave the world the electric light, the movie camera, and hundreds of other important discoveries. Here is a book that will delight the technical-minded boy or girl who loves the adventure of learning how and why.
