Review: Fun to watch grow. - Bought this as a gift for an 11-year-old and he absolutely loved it. We even received photo updates during the process because the crystal growth was so exciting to watch. While the crystal came out clear instead of green, it still grew to look almost exactly like the photo in shape and size. Overall, this was a big hit, easy to do, and a fun STEM activity that actually delivers impressive results. Great gift idea for curious kids.

## Questions & Answers

**Q: How long does it take for the crystals to grow?**
A: Left undisturbed, you should see crystals begin to form within a day or two and full growth between 7-21 days depending on location and temperature.

**Q: are the chemicals used to grow these crystals toxic? Are the crystals safe to handle once they've grown?**
A: Our Crystals can be handled once they are grown. We do recommend washing hands after contact.  For more information please contact us directly at help@natgeotoys.com

**Q: Can you reuse the seed rocks to make new crystals?**
A: If you have additional powder, you should be able to grow an additional crystal reusing the seed rock.

**Q: Can you touch the crystal**
A: Yes, once your crystals have completed their growing process, let them dry thoroughly on a paper towel, and then they will be ready to handle.  Although they are safe to handle, we do still recommend washing your hands after handling.
