polishedrocks.jpgtumbler.jpgI had no idea what rock tumbling was till I bumped into Erocktumbling.com. It is actually a hobby that a family can enjoy together. Nephew Ccino would always talk about it and ask if I could get him one or two rock tumblers for himself. This one in the photo is a rock tumbler extensively used by serious hobbyist, laboratories, schools, and industry for an unlimited variety of tumbling and mixing operations. However, you can also get a toy version from your favorite toy shops for your curious kids. The most common type of rock tumbler is a rotary drum tumbler that polishes rocks by simulating the action of the ocean waves. Some families use this to polish stones or rocks for their home garden and landscaping activities.
