Transform ordinary rough rocks into stunning, polished stones! These polished stones can be used to craft a variety of items such as charms, bracelets, and keychains. Start by putting the included rocks in the tumbler's barrel along with water and grit. Then, repeat the tumbling process with gradually finer grits. In just a few weeks, this amazing Smithsonian rock tumbler replicates the natural process that oceans take thousands of years to complete!
Using the Smithsonian Brand Rock Tumbler is easy. First, put the included rocks into the barrel and add water and the coarsest grit provided. Close the barrel and turn on the tumbler. Let it run for a set period, usually a few days. After that, drain the water and grit, and replace them with a finer grit. Repeat this process with progressively finer grits until your rocks are beautifully polished. As for precautions, always make sure the barrel is tightly closed before starting the tumbler to prevent any spills. Also, keep the tumbler away from children when it's running. For maintenance, clean the barrel thoroughly after each use to prevent grit build - up. This will ensure the long - term performance of your rock tumbler.
