Review: Great Kit - Got this for my 6 year old niece and she loves it! Very easy to understand and follow. Good quality and fun to do with the family!
Review: Pretty cool!! - I did not have high hopes after reading some of the reviews, but the whole family actually liked them! 2 kids, 2 parents and grandma each made one. You color a paper tree with markers. As you can see in the pictures, only the blue and purple markers really showed up. (Maybe try using other markers?) We did them around 8 p.m. The crystals started growing after about 45 minutes, and we were all surprised at how cool they were the next morning. I think one of the key things is to wet the tops of the trees with the crystal solution. As others have said, this is a throw away project - the crystals are not sturdy enough to keep.

## Features

- 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.
- HIGH-QUALITY EDUCATIONAL TOYS - We proudly make the highest quality hands-on science toys, and all our products are backed by exceptional service. If your experience isn't stellar, we'll make it right!

## Questions & Answers

**Q: How long does it last if not touched?**
A: The crystals are a powder crystal that do dry more and more as time goes on.  I have seen them begin to flake off within days or remain in place for months, I am not sure if the amount of solution used makes the difference.  If they flake off, you can gather them in the tray and sprinkle water on them to watch them grow again!

**Q: What is the solution used exactly?**
A: Potassium Phosphate Monobasic
