GROW CRYSTAL COVERED TREES – Watch as crystals start to grow in minutes from the branches of the included evergreen, cherry, bonsai, and dragon blood trees like magic! The 6 trees will be fully covered in crystals in as little as 6 hours.
YOU CHOOSE THE COLORS – Color each tree any way you’d like with the 5 watercolor pens in the kit, and grow crystals in the colors you’ve chosen. It’s a craft project and crystal kit all in one!
REAL SPECIMEN INSIDE – After the crystals are grown, you’ll enjoy examining the genuine geode specimen in the kit! A full-color learning guide is included and is packed with fascinating facts about crystals. This STEM craft kit is unforgettable!
COMPLETE ACTIVITY SET – Because the crystals absorb the ink from the markers and grow in the colors drawn, this kit combines the science of a crystal growing lab with the creativity of an art project, making this a great activity for girls and boys.

Customers find the crystal growing kit to be a fun STEM activity that’s easy to use and pretty to look at. However, the crystal growth results are mixed – while some report quick growth, others say no crystals grew at all. Moreover, the kit’s quality and effectiveness receive mixed reviews, with some finding it awesome while others describe it as terrible, and some saying it works well while others report poor results. Additionally, durability is a concern as the crystals fall apart easily, and customers consider it not worth the money.
