4M Crystal Growing Kit - DIY STEM Chemistry Experiment, Grow 3 Colored Crystals

4M's Crystal Growing kit lets kids mix and seed three colored crystal compounds to grow their own crystals, watching chemistry turn into a real, visible result. A diagram on the box shows which base combinations produce which crystal colors, so kids can experiment with different pairings before seeding their mix. It's a hands-on introduction to geology and chemistry for kids curious about how crystals actually form, built around real observation rather than a quick craft project.

• Includes three colored crystal seeding mixtures for growing distinct crystal colors
• Box diagram shows which base combinations create which colors, adding a layer of experimentation
• Grown crystals reach approximately 4cm x 5cm (up to 5cm wide and 4cm tall)
• Covers STEM basics like chemical reactions and crystal growth, with a focus on geology and chemistry
• Recommended for ages 10+ with adult supervision required throughout the experiment
