Rock Tumbler

Amp up your rock collection and explore the secrets of geology with a rock tumbler! User-friendly machine allows budding geologists and gem collectors to transform rough stones into beautiful polished rocks while exploring topics like erosion, weathering and the geological rock cycle. Kit comes with an assortment of authentic rock samples to get you started, such as amethyst, aventurine, rose quartz, and more, plus four polishing grits. Use the included jewelry settings to create accessories from your specimens. The powerful, long-lasting motor is built with durability in mind: once you've polished the included rocks, you can continue your experiments by tumbling rocks, glass, wood and other materials you collect on your own. Features a leak-proof, noise-reducing barrel and built-in timer. 6-page manual guides children on their rock-polishing adventures, providing usage instructions as well as a wealth of scientific information about different types of rocks, how they are formed, and more. Powered by USB-C cord. Ages 8 and up.
