Description
Turn science into spectacle with this classic crystal-growing experiment. Drop the "magic rocks" into the solution and watch as colorful towers begin to sprout, rising underwater into a miniature crystal garden within minutes. Each formation grows to different heights—some reaching up to 4 inches. What's really happening is chemistry at work: metallic salts react with sodium silicate to create colorful, branching columns.
Now in updated packaging—same hands-on STEM activities inside!
