Description

Let’s rock and roll! Amp up your rock collection and explore the secrets of geology with the Thames & Kosmos Rock Tumbler! This custom-designed, 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. The kit comes with an assortment of authentic rock samples to get you started — including amethyst, aventurine, rose quartz, and more — as well as 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. The leak-proof, noise-reducing barrel and built-in timer also aid in ease of use. The included manual and poster guide 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.

USER-FRIENDLY: Budding geologists can easily transform rough stones into smooth, beautifully polished rocks!

CUSTOM DESIGNED: The powerful, long-lasting motor is highly durable and the leak-proof, noise-reducing barrel aids in ease of use. Also includes a built-in timer with various settings, allowing the tumbler to run for up to seven days!

ASSORTED SPECIMENS INCLUDED: Kids ages 8 & up can start with the genuine rock samples that come with the kit -- including amethyst, aventurine, rose quartz, and more -- as well as four polishing grits. Then move on to other rocks, glass, wood, or other mateirals you collect on your own!

EDUCATIONAL VALUE: Explore the secrets of geology, diving into topics like erosion, weathering, and the geological rock cycle as you amp up your rock collection, guided by the included manual and poster.

BONUS SPECS & EXTRAS: Includes jewelry fasteners to transform your rocks into accessories. The rock tumbler has a 450g capacity (over 1 pound) and a USB-C power supply
