Smart Science Tricks - Tapa dura

Reseña del editor

More fun than magic, these hundreds of tricks, puzzles, illusions, and experiments all rely on the amazing powers of science and nature. Cause an ordinary egg to float halfway down in a glass of water. Turn one half of a flower blue and the other red. Lift an ice cube out of a glass with a piece of string. Make a paper bug that moves with the help of a lemon. Push pins into a balloon without bursting it. With readily available supplies, most of which you'll already have on hand, you can explore the wonders of water, air, friction, light and mirrors, mathematics, sound, gravity, magnetism, perception, and more. Every trick includes a scientific explanation of why it works.
