Evviva Sciences Crystal Growing Kit for Kids Science Kit to Make & Grow Rocks, Crystals, Gems – Easy All Inclusive Set – Chemistry, Geology & Learning Experiment Toy – w/eBook

Honestly, this was a great kit and its super easy (with clear, simple instructions). I have a 10 year old son and a 5 year old daughter who both took part in making their crystals. It was fun to watch them grow over the week. Each morning, the kids were super excited to see the growth in both and compare them--surprisingly enough, they both grew at different speeds. It was great to talk about the science and math behind it. I would highly recommend this kit!

I was a little hesitant to try a new crystal growing science experiment because the last kit I purchased was a disaster and I did not get a single crystal! I decided to give this kit a chance and it worked like a charm! I had a few questions, and customer support was extremely friendly and very helpful. A small warning is that the science experiment can be messy, so make sure to use the kit on several newspapers. But otherwise, very easy directions and very very fun!

Instructions were easy to follow, everything was clearly labelled. Unfortunately, despite following instructions to the letter, the crystals never really formed. There was still a lot of liquid left in the container after waiting a week as instructed. Even worse, the liquid leaked all over the kitchen counter, ruining some of the cabinets. Given the lack of similar reviews, I assume we got a dud? Very disappointing.

So the crystals grew a bit but they ended up more spreading across the contained and when taking them out there was just sort of this small hump for the crystal and the a hard square underneath it where the crustal stuff solidified. We followed directions to a T and waited the exact amount of time.We'll try the star and dolphin and update review if things turn out better.

I bought this as a gift, for my 10 year old niece, to reward her for being accepted into gifted and talented classes. She was very excited to make them to give to her teacher. So far we've made two of the regular crystals. They both came out pretty cool! I really liked how the company takes their time to follow up with the condition of their product and even sends emails with instructions letting you know how to grow the best crystal possible. I would definitely recommend and would purchase from them again! I wish i could have taken pictures of the crystals before she gave them to her teacher to show on here.

As other reviewers have mentioned, this Crystal growing set not only works, but grows huge crystals. It worked so well, it kept growing crystals even when the foam form was taken out! My daughter has not tried to grow the shapes yet.

We had our grandkids for a week - and wanted some fun science activities. They enjoyed being part of the process and watching the daily progression. Great project for kids - the crystals were beautiful!

The Crystal Growing Kit was a gift for our 10 year old neighbor. She loved receiving it and I loved the excellent customer service follow-up. The tips (that I passed on to her) were a great help and the attention to detail by this vendor was appreciated.
