Have you ever noticed that the rocks at the beach or on a river bed are much smoother than rocks you find by the side of the road? Why do you think that is? Here's the big secret: nature polishes rocks by using water and other rocks.

In fact, sand is just rocks that have been broken up and polished into tiny grains that we don't even recognize as rocks anymore! This long and incredible process is called erosion.

Erosion is the natural process of something breaking down over time. By tumbling rocks with water and grit, we create a controlled erosion process. Rock tumblers make this possible, and we have some of the very best.
