National Geographic Mega Crystal Growing Kit for Kids- Grow 6 Crystals with Light-Up Stand, Science Gifts for Kids 8-12, Crystal Making Experiment, Science Kit for Girls and Boys (Amazon Exclusive)

The product is amazing! You can create various types of crystals with your children. It's very exciting as the crystals grow. Crystal growth takes 3 to 7 days for best results.

Bought for a 7-year-old as a Christmas gift. He loved it continues to play with it as it grows and as he grows. I believe it was worth the money.

This was a gift for my 9 year old for Christmas. He liked it, easy to do and the crystals mostly did great. Out of the 6 , only 1 didn't grow very well. Unsure why. Be aware the light up device only holds 5 crystals, not 6. The instruction booklet is outdated. It sent you to a video link that doesn't work, but it's easy enough to youtube "national geographic crystal growing". Another point is that the video instructions conflicted with the booklet. One said "grow in the dark".. the other said "grow in the light/warm room".. In the end we did half the batch like the video and the other half like the booklet. It was a great learning experience in experimenting and teaching my son to observe which was 'better'. The box also contained just 2 plastic containers.. but we used glass cups from our kitchen since you have to wait 7+ days. We experimented which did better in the soft plastic container v.s. glass cup..

My 11 year old loves these experiments! Even my 5 year old grandson loved doing it with his Uncle! Getting the lighted base with it is the cherry on top! Only issue was it didn't have instructions in the box (I easily found a video with instructions online) I would recommend if you have a child who enjoys this kind of stuff and it was very easy.

Our niece got two of these for Christmas, she’s just over the moon about them. She even created a science project without an assignment. She just wanted to share with her classmates her excitement.

kid thought it was awsome and i had fun doing it s well

The children loved it!

My granddaughter Ellie and I loved making these crystals and waiting the week gave her a schedule where she had to check him every day to make sure they were growing so she had a sense of responsibility that she was helping him grow by checking in on him she's only three and a half but she's learning responsibility already the crystals came out beautiful
