To achieve great things, you have to be willing to take risks-and as Edison's Concrete Piano reveals, some of the most famous names in history experienced plenty of flops and face-plants in the course of their careers. Thomas Edison, for example, not only revolutionized the world with the light bulb, but also designed a concrete piano, a nonoperational helicopter made from box kites and piano wire, and a machine to speak to the dead. Alexander Graham Bell, inventor of the telephone, actually devoted most of his time to his sheep farm in Nova Scotia-devising a multi-nippled sheep somewhere along the way. You'll also learn about Leonardo da Vinci's walk-on-water shoes, George Washington Carver's miracle peanut cure, and much more. The ludicrous ideas, faulty designs, and offbeat hobbies in this volume will inspire laughs-and serve as a reminder that even the very best minds make mistakes.
