amazing gift !! value for money

My daughter had fun making this kit. She needed help with the crystals as it requires boiling water. She had fun watching the crystals grow and arranging her sand. We grew crystals from a different type of kit and used them in the final set up because they were less messy, fit in the bowl better, and were more uniform than the ones we grew that came with this kit. The color on the crystals from either were not vibrant or uniform. The ones pictured in individual cups came with this kit. The ones on the sand did not. Daughter is happy and had fun that's all that matters.

I did this with my daughter. It was super fun to watch her run to the window every morning to see how big they had gotten. The only words of wisdom I have for this is be sure it is not too close to whatever is beside it. I had it on the window seal and it grew and attached to the window frame. It took a good 10 mins to get the color scrubbed off of the frame. Other than that it was pretty cool!

The whole rest of the kit is super cute, but the crystals was REALLY disappointing. And obviously thats the point of the whole kit. We decided to follow the directions and go all out, letting the crystals grow for 10 days max. BIG mistake, but also apparently didnt matter." The solution was supposed to be completely untouched with good natural lighting, and we gave it that. But by day 2 the liquid seemed to evaporate a great deal. Day 10 I removed the solution and was left with a disk (size of the growing container) of extremely delicate crystals. To get everything to fit, I had to break off the crystals that grew away from the "rock" they were supposed tp grow on, before putting them into the terrium. It was just like trying to break off a millimeter layer of ice, super easy and brittle. We lost a LOT of crystals that way. In the end, all of the grow rocks were completely visible due to poor growth even after the longest allotted time. The crystals are VERY thin, ice density. I was very hopeful but I wouldnt buy again for the crystals.
