This book is a teacher's dream. In it are over a hundred very simple demonstrations that make physics come alive for students. This text can be used whether you teach kindergarten and want to show the children some neat "tricks," middle school where you're trying to capture their attention, or high school when the student really needs to understand the principles of physics. It is the kind of book that is hard to put down as you exclaim again and again, "So THAT'S how it works!"
