Klappentext

Have you ever wondered why a 10-tonne boat floats but a tiny pebble sinks? Archimedes knew why. How does a basketball or tennis ball bounce? Robert Boyle could have described how! Can you explain why a hot-air balloon rises but a balloon you blow up drops to the ground? To answer these questions and many more, author Paul Fleisher explains the laws that define how and why liquids and gases behave the way they do. Through simple experiments, detailed illustrations and concepts that are easy to understand, readers are introduced to the basic principles of fluid mechanics in a fun, exciting way.
