Smithsonian Crystal Growing Geodes

Click for details
Nature takes thousands (or even millions) of years to produce a single, magical geode--a crystal-lined cavity sealed away within a rock. With the Smithsonian Crystal Growing Geode Set you can grow your own collection of geodelike specimens in just a matter of days. This safe, simple-to-do kit includes geode and crystal-growing chemicals and supplies (not including a few household items like a saucepan, a flashlight for observation, and glue) to make a plaster geode "shell" in which to grow purple "amethyst" crystals. Directions are clear and specific; space for record keeping and lab notes is included. An informative pamphlet brimming with gorgeous photographs details crystal identification and structure and various types of formations. (Ages 10 and older; adult supervision recommended)
