This is the perfect book for the young person who wants to know how things work, and why they work: more than 200 simple experiments that are not only entertaining but educational. As the experimenter learns to light a fire with ice, to create rain indoors, to use a wrist watch as a compass, he also learns about astronomy, botany, chemistry, physics; he is gently introduced to the principles of electricity and magnetism, heat, light, sound, gravity, momentum and inertia, and even the human senses. Each project is illustrated and includes clear instructions and explanations of cause and effect. Each is safe and easy to do, and the only equipment and materials necessary are simple tools and ordinary household articles. Children of all ages - and their parents too - will find that this book both stimulates and satisfies their curiosity.
