Experience the wonder of chemistry in action with the Smithsonian Magic Rocks Kit, an exciting STEM activity where kids create dazzling crystal formations right at home. The kit includes specially formulated “magic” stones and a crystal-growing solution that produces spikes, towers and coral-like structures in bright, vivid colors. Kids simply place the rocks into the solution and observe as the growth begins almost instantly, with full formations emerging over the following hours.

Designed for ages 10 and up, this project combines science and creativity—making it ideal for classrooms, independent learning, science fairs or fun weekend experiments. As children watch the reaction unfold, they learn about crystal formation, chemical interaction and the real-world uses of crystalline structures in nature and technology.

Once complete, the finished crystal scene becomes a stunning display piece. Whether gifted to a budding scientist or used as an immersive educational tool, Smithsonian Magic Rocks delivers fast-paced excitement and lasting inspiration.
