## Customer Reviews

### ⭐⭐⭐⭐⭐ Lab activity for kids.
*by J***Z on January 8, 2026*

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.

### ⭐⭐⭐⭐⭐ Worth the money buy it
*by E***O on January 18, 2026*

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.

### ⭐⭐⭐⭐⭐ Fun , easy, educational. Don't recommend for too young kids who don't have patience.
*by B***T on January 7, 2024*

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 The instruction booklet is outdated.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..
