Grandchildren enjoyed the experience and fun growing the crystals, which were a Christmas present. Now they have them to enjoy. Colorful, assorted shapes. Fun!

Incredible last minute choice for the grandchildren for the holidays. They were so enthused about getting this for Xmas they IGNORED the things they'd asked for to inspect and try it. Not pseudo-scientific but the real thing, and the kids were knocked out. Best money I ever spent at Overstock! They are going to keep me posted as to how the crystals are growing!

This came very quickly, even though it was during the holiday rush. It is fun, educational and a great interactive experience for the whole family. I bought it for my boyfriend's son and he loves it!

Now, I have to wait for CHRISTMAS to see if it is a BIG hit! But, it all came, as promised, and looks like an excellent gift for my 8-year-old daughter.

Awesome, fun, and the kids learn a lot..Great fun for the whole family! very educational as well!!

bought for my 7 year old grandson who loved the interacting and growth process of the product. Would recommend this product for any child that has a health curiosity.
