Can you blow a square bubble from a square hole? Do you know how the narrow beam of light from a film projector fills up a big movie screen? Finding out the answers to these questions isn't just fun--it's physics, and will help kids understand all the wonderful things happening in the world around them. In addition to being a really cool trick, crushing a plastic bottle without touching it teaches budding scientists about air and gases. Floating an ice boat reveals the basic properties of water. And youngsters will feel the force--of gravity--by jumping up onto a chair. Whether they're making money talk or launching their own astronauts, children will really enjoy these activities.
