A piece of paper uses physics to balance a textbook… and much more!
If someone told you that they could balance a full-size text book on a piece of paper, you might call up the looney bin. That’s a crazy idea, right? Well, the notion that a book can sit, precariously, atop a plain piece of paper isn’t quite as bonkers as you might think! With a little knowledge of physics and geometrical shapes, you can perform the Balancing Act, too.
