Turn rough rocks into beautiful, polished stones that you can use to make charms, bracelets, keychains, and more. Begin by tumbling the included rocks in a barrel with water and grit, then repeat this cycle using progressively finer grits. In just weeks, the Smithsonian Rock Tumbler mimics the process that takes oceans thousands of years!
