We think of them as ordinary objects, but rocks can do

amazing things: there are rocks that glow and rocks that

travel through space, rocks that float and rocks that burn.

These are only some of the surprises in Weird Rocks, a musthave

guide for young rock hounds. Author Michele Corriel

introduces readers to sixteen unusual rocks and explains

the science behind what each one does and how it does it.

Youngsters will discover what makes one kind of rock smell

like a rotten egg, what rock acts like a magnet, and what

rock contains hidden treasure. High-quality photographs,

colorful paintings, and hilarious cartoons add visual delight

to this entertaining and informative book.
