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)

My 5 year old son and I had so much fun making these crystals. It’s a good value and easy to use and clean up was a breeze. The hardest part was finding a place in my home to set it where it would be undisturbed while the crystal grew. But when it was finished we had big beautiful crystals! I love the lighted stand to display your crystals on but you have to be super careful removing the crystal from the silicone growing container or you will break shards off of your crystals. Totally worth the money! We still have a few more to grow. I personally can’t wait to do the glow in the dark one!

Was a gift for 2 kids - they love it and now use the night light.

Fun crystals to grow, I let them grow for about 2 weeks and they turned out really well. The only issue I had was removing them from the seed rock, I completely destroyed a crystal trying to remove it and didn't bother with the other crystals. The light up display is a cool idea and based on other reviews they turned out great, I just had troubles removing the crystals without destroying them. Photos were taken with a DSLR and a macro lens.

Grandson loved it

This product is fantastic for hands on fun and it turns out to really cool thing to have around when complete.

I really thought this was pretty cool! My 6 yr old did also, but I did most of the work. I grew three at a time in pint glasses and let them grow on a shelf in my son’s walk-in closet (where I knew the cats couldnt get at them). Overall, super neat. I let them grow the full 7-day period. So, be patient! Definitely get out all the supplies you will need before conducting all the steps. I highly recommend setting up the area beforehand, too.

I love the Nat Geo gifts. I had previously gotten my son a science experiment kit, which included 1 crystal-growing experiment. He loved it so much, I thought this would be a really cool addition for a Christmas gift. The set is very nice and comes as advertised; however, the crystals did not grow as well as I expected (based on the previous Nat Geo kit he had). The provided cups for the experiment really did not work at all; the ones we grew in plastic cups we had at home turned out better. My son liked it, and it was a cool gift, but the crystals did not grow as big or well as I expected. The set-up kit with lights is very nice and he still uses that.
