Product Details
Discover the beauty hidden inside everyday rocks with the Smithsonian Rock Tumbler, a hands-on STEM kit that teaches kids how natural forces shape and polish stones over time. Fill the tumbler barrel with rough rocks, add polishing grit and water, then let the rotating tumbler mimic real geological erosion. Over several stages, jagged stones gradually transform into smooth, glossy gemstones ready for display or crafting.
The kit includes multiple grit stages, assorted rough stones and jewelry accessories, allowing kids to turn their polished pieces into necklaces, keychains or keepsakes. A step-by-step instructional guide explains the tumbling process and introduces geological concepts like erosion, abrasion and mineral composition.
Perfect for hobby collectors, STEM learning at home or classroom science, the Smithsonian Rock Tumbler blends science discovery with creativity and rewarding results. Once complete, polished stones make stunning displays, gifts or additions to rock collections.
