Science is at work everywhere--in the kitchen, the sky, the ground,
and all around us in plants, animals, machines, even the mind. Here are
100 ways to demonstrate how science works and for you to come out
tops at your school fair. Stir up chemical magic and turn a copper pot
green with oxidation. Prove that computers emit radio waves; create
virtual 3-D with a polarized lens; and show off some "medieval ballistics."
Every experiment will impress the judges!
