Young scientists deserve educational equipment as much as chemists or rocket scientists. Rock tumblers certainly fit in this category and can be a great fun and educational tool. Tumbling rocks to a glossy finish demonstrates the principle of mechanical erosion, while also teaching your child that geological processes tend to be quite slow.
As a hobby, rock tumbling is not merely an educational one with this U.L. Listed rock tumbler. When the experiment is complete, the tumbler delivers a beautiful, high luster batch of stones to keep as cool earth science souvenirs, jewelry, and crafts.
This package includes a rock tumbler machine, rough semi precious stones, grit, polish, jewelry settings, and detailed instructions. Start with the agate, jasper, amethyst, and more included.
Per-minute revolutions: 50-80
Four grit cycles for immaculate polishing
Includes: rock, tumbler, polish, gems, jewelry settings
Weight: 3.5 pounds
Dimensions: 8.5L x 4.25D x 45H inches
