    • Fun , easy, educational. Don't recommend for too young kids who don't have patience.
Style: 6 Crystal Lab
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 The instruction booklet is outdated.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.. ... show more

Do not use glass!! Only do 2 at a time using the silicone cups that comes with the kit. Yes, it takes longer… but that just extends the fun! LOL! I actually let them sit for a week. But a crystal crust does grow over the cup so make sure you have something underneath! I didn’t remove the seed rock. Didn’t seem necessary since it was flat. Worked great! ... show more

    • Great gift for a curious kid
Style: 8 Crystal Lab
My niece absolutely loved it and her mom said it kept her entertained for quite a while (a feat of greatness alone) The box did come pretty banged up so that was a bummer.

    • Found a new hobby and side hustle
Style: 8 Crystal Lab
Review Image by Sidney Sidney
I saw a few social media videos on growing crystals, and took the leap with a trusted name in science for my first experiments. It gave me the confidence to grow my own crystals, do more research, and start a profitable side hustle growing crystals for others. Assembly and instructions were so easy, a 3 year old could do it with the assistance of mom or dad. ... show more

    • Fun but seed rock doesn’t come out
Style: 8 Crystal Lab
This is really a neat idea. It was very hard for my daughter to wait 7-10 days but a great learning experience. She has eagerly been checking the crystals all week. We removed the crystal from the rubber cup tonight and she was sooo excited but the seed rock absolutely will NOT come out and the crystals are just crumbling as we try - we have used several different types of spoons to remove it as well. Leaving it alone for awhile to see if the seed comes out easier when dry bc it certainly doesn’t when wet!! ... show more
