Rocks rock.

People do not usually pay attention to rocks. Their ubiquitous presence almost every where had made them invisible to people.

But actually rocks can be interesting - from the rarest and most precious gems to the most common stones. Rocks have a science that we can all study and learn which in turn can give us a better understanding of our world. But aside from that, rocks can also be treated as materials for creating art and tools for amusement to challenge our creative imagination.

Truly rocks rock!
