Our fast-paced world of fax machines, digital cameras, and cell phones is possible because of the work of inventors who paved the way for modern communications. Meet: Reginald Fessenden, who thought of a continuous wireless signal when he noted the ripples resulting from a rock he tossed in a lake; Alexander Graham Bell, who made his famous call - "Mr. Watson, come here! I want you!" - because he had spilled acid onto his trousers; William Stephenson, inventor of the wirephoto, who was a spy during the Second World War. From newsprint to fiber optics, discover ten great inventions in this fascinating book, and a great resource for science projects and science fairs: - Make your own paper - Create your own halftone image - Make your own pinhole camera - Make a telegraph - Use Morse code - Make a light fountain
