Rock Tumbler Apparatus

Have you ever seen smooth pebbles and rocks on the beach or river bank? A long, long time ago these were rough rocks. Over time, the action of the water and the sand gradually made them smooth. Now your students can recreate in a few weeks what nature does over thousands of years. They'll use the easy-to-operate tumbler and included agates and abrasives to turn rough rocks into beautiful stones! They can even use the polished rocks to create their own jewelry. Comes with comprehensive, illustrated student and teacher guides. Size: 9"L x 5"W x 5"H.
Refill package set of agates and abrasives is available separately.  Recommended for students in grades 6 through 12.
