National Geographic Rock Tumbler: Discover the world of rocks and minerals! The rock tumbler kit from National Geographic will allow children and adults to transform rough and dull rocks into colourful and gleaming stones. It even has a window that lets you watch the week long process unfold. This rock tumbler polishes small stones to a smooth gleam over a period of a week that uncovers their incredible hidden patterns, colours, and structures. Used with the included 226 grams (8oz) of gemstone rocks, or rocks that children collect, the results encourage geologic study and create beautiful objects to behold. The Rock Tumbler kit includes two bags each of coarse, fine, polishing, and finishing powders. In addition there is a craft starter kit so children can make their own jewellery with key chains, setting holders, a necklace chain, adjustable rings, earring wires, and jump-ring connectors.
