The Kosmos Green Crystals Growing Kit is a chemistry experiment set that lets children grow their own green crystals at home. It combines a real scientific process with a fun, visual result that makes chemistry tangible and exciting.
Grow real green crystals step by step with the included crystal-growing solution
Introduces core chemistry concepts like crystallisation and saturation in a safe, hands-on way
Includes all necessary materials for a complete experiment — no additional supplies needed
10-month manufacturer warranty provides peace of mind for parents and educators
What makes the Kosmos Green Crystals Growing Kit special
Unlike simple craft kits, this set guides children through a genuine scientific process: dissolving, cooling, and observing crystal formation over several days. The green crystals that form are visually striking and serve as a lasting reminder of the experiment.
Ideal for curious minds aged 10 and up
Designed for children who enjoy experimenting and asking questions about how things work. The kit is a perfect introduction to chemistry for school-age kids who want to move beyond theory and see real reactions happen in their own hands.
How to use the Kosmos Green Crystals Growing Kit
Prepare the crystal-growing solution using the included ingredients
Seeds or a starter crystal is placed in the solution
Leave the setup undisturbed in a safe location for several days
