HAVE YOU EVER WONDERED
Why big ships float?
How yachts use wind to sail?
How jet-skis ski and hovercraft hover?
What instruments a ship's captain uses on the bridge? How submarines use sonar to see underwater?
Then BOATS, SHIPS, SUBMARINES and Other Floating Machines is the book for you. Like all the books in the HOW THINGS WORK series, it demonstrates that science is both fun and central
to our everyday lives.

Each book has easy-to-read text and detailed colour illustrations, many of them cut away to show what machines are like inside. Special Focus On boxes highlight and explain important scientific principles, and simple TEST IT OUT! experiments and activities let you discover for yourself how things really work.
