Description
Discover how spies use science to keep—or uncover—top secrets. This engaging book contains 40 different scientifically-sound projects that are safe, easy to do, and require common household materials. Features such activities as writing in invisible ink, sending a message in Morse code, building a listening device, and visiting the CIA’s home page on the Internet. Includes scores of delightful illustrations, dozens of ideas for “More Fun Stuff to Do” and “Spy Science in Action” sections which show kids how the scientific principles they’ve learned are involved in actual spying.
