This is a great little “Crystal Growing Kit” that you can find on Amazon for around $10. The key here is to follow the directions very carefully, which not only ensures the success of your crystal growing but it provides a strong foundation for learning about science and teaching kids to follow instructions.
We tested this kit with a six year old and an eight year old, and I would say it was perfect for them, although you could even go a little younger if you are prepared to assist with the project. Everything you need is included in the kit except for water. We began by dissolving the powdery crystal mixture in hot water and letting it sit for 15 minutes. Then we transferred that to the clear crystal display case and waited another 30 minutes for everything to settle. Next we put in the multi-colored crystal seeds, and according to our watch, the preparation process took about 60 minutes.
After a few hours the crystals began to grow, and the kids were tasked with checking the status of the crystals every morning. The crystals were fully grown after about 5 days, and we were surprised that the cluster of crystals grew so big, actually filling the container. Although this was only our first foray into crystal growing, we took notice that you can also grow crystals of different sizes as well. Overall, this was an easy rewarding science experience for sure.
Toys Bulletin is happy to give this kit a thumbs up. We would especially recommend it for birthday parties, either as a gift or a fun activity for the kids to do.
