The instructions are pretty easy and the steps are pretty kid friendly, as far as stirring and mixing goes. An adult does need to help, though, since there is hot water and powdery elements involved. Be mindful of the glass you use to grow the crystals in. Make sure the top of the glass or jar is as wide as the base. I used a tulip glass and found myself breaking the glass with a hammer in order to get the crystals out. The crystals themselves are pretty cool, too. I let them sit in the glass for about two weeks. And, yes, they do glow in the dark. The kit also includes a large flourite crystal and some education on crystals in general. The kids really enjoyed it and would check on the crystals' growth every day. Review: Interesting look! - My daughter enjoyed the project very much. We finally drained the remaining liquid today and removed the crystal from the growing chamber. It did break when being removed but we ended up with a decent sized chuck. I was out of paper towels so I grabbed a sheet of foil to place the crystals on until the completely air dry. Well, my husband came home from work and pulled me aside. He asked very bluntly why there is meth on our kitchen counter. I googled pictures of meth and it sure as heck looks like meth. We got a good laugh. I definitely won't leave it sitting out on foil anymore though. We will check if it glows in the dark and I'll update if it doesn't. ## Features - DAZZLING CRYSTALS - The perfect family activity.

We back our kits with 100% satisfaction, if you have any issues with your kit, please contact us directly at help@natgeotoys.com **Q: Do the glow in the dark crystals really glow?** A: Jim, thanks for your question. Yes the “seed” crystal will glow, it is fluorite, a naturally occurring crystal that will glow. After the crystals grow, expose them to bright light for a few minutes. Then, take them to a dark room to see the glow. **Q: Do you need any additional supplies outside of the kit to grow? Some kits require an old sauce pan.** A: Hello Shannon,The only extra items you will need for this kit are a jar or container to grow the crystals and the hot water to add. I hope you enjoy your kit!

We finally drained the remaining liquid today and removed the crystal from the growing chamber. It did break when being removed but we ended up with a decent sized chuck. I was out of paper towels so I grabbed a sheet of foil to place the crystals on until the completely air dry. Well, my husband came home from work and pulled me aside.

The first time I grew this with my son, I dissolved the powder in 1 cup of water as directed to in the booklet. I got a cloudy solution, and I remember at the time thinking if I should strain it or not to avoid crystallization points in other areas besides the seed rock. Unfortunately I didn't, and after letting it cool for 15 minutes, I added the seed rock and noticed a rim of "snow" already. After 5 days there was nothing other than a crystal snow, which although impressive, was not our goal. The seller sent a second package with the instructions: Please take these steps with your next experiment in order to achieve optimal results: 1. Use a clean (be sure there is no soap remaining after you wash) glass jar as a growing chamber. A wider mouth works better as it allows for more evaporation during the process. 2. Use VERY hot water as indicated by the instructions (adult supervision required). (Filtered or distilled water will work best because it will be free of other dissolved material) 3. After dissolving your crystal growing powder, let the solution cool for about 15 minutes before adding the seed crystal. 4. Once the seed crystal is added place your prepared growing chamber in an out-of-the way place where is won't be disturbed for the during of the growing process. Here are the alterations I used: I used 1.25 cups of water instead of 1 cup. This fully dissolved the powder into a clearish solution. I then quickly filtered it with an Aeropress (which can handle hot liquids). This gave a very clear solution. Then after cooling, I added the seed crystals. I am unsure if you can just gravity filter with a funnel and some loose coffee filters, but the Aeropress was easy. This worked much better and the crystals are slowly growing on the seed crystal. I suspect the process might be faster if I used less water and had a saturated solution, but I didn't want snow again. This experiment was less of a sure-shot than the Ice Age kit that we got (which grew both snow and large single crystals).
