Description
Earth science, illuminated. Grow vibrant, multicolored crystals right at home with this Smithsonian kit designed for hands-on discovery. Kids can create 10 unique specimens—including frosty diamond-shaped crystals and dramatic spiky formations—using real chemical reactions with potassium sulfate and ammonium phosphate. A light-up LED display base cycles through colors to make finished crystals glow.
Along the way, kids learn about crystalline habitats and molecular structures, guided by a full-color poster and all the tools they need: chemical powders, mixing sticks, granite stones, safety goggles, and more.
Now in updated packaging—same hands-on STEM activities inside!
