Crystal Growing Kit for Kids - Science Experiments for Boys and Girls Ages 6-12 Year Old Girl Gifts - Boy Craft Toys STEM Crafts Activities, DIY Projects Kits - Gift for Kids age 6 7 8 9 10 11 & 12

A birthday present for 10 year old grand-daughter, don't have any feedback yet.

Took 3 weeks to see results. Also Daddy drank one by mistake. We don't know long term effects but he seems normal for now.

I cannot comment as this was a gift

Turned out really well, unfortunately my little miss broke them abit before I got a photo taken of them. Still look OK though.Only one thing I would fault is I wish the part holding the stone off the bottom of the pot was higher. We ended up with square crystals stuck in the bottom of the pot, which resulted in me severely cutting myself on one of the cystal trying to get it out of the pot. The others where then rather scary to get out. Actually needed it glued which was rather embarrassing trip ( stitches basically, but I'm allergic to stitches )

Disappointed by the size of the finished object.

Whilst I did receive an email request from the company to leave a review, it has simply served as a reminder. Myself and my daughter started growing these crystals 7 days ago and all three are almost ready to be mounted on the supplied base. I recommend the highly to anyone with interest in growing crystals, placing the 'seed' is a little fiddly, you should put the solution in there final growing place before placing the seeds, as if they fall off your crystals won't grow as well. All in all a great product and my daughter has enjoyed the whole process so far.

I bought this for my sons birthday, we had a fun afternoon setting these up, we followed the instructions and marked them off the callender for a week and 1 day and the results are amazing my son loves them and the light display is amazing aswel as you can see in picture also great as a night light aswell

I bought this for my grandson, who has not had it yet, so no feedback on that front. I was however disappointed to find that all three crystals used the same compound (Ammonium Dihydrogen Phosphate), and that the colour is just dye. This is surely a missed learning opportunity - that different chemicals produce different coloured and different shaped crystals? I know the substances must form good crystals fairly quickly, and it must not be poisonous, so this will limit the choice. Nevertheless I would have hoped that three different chemicals could be found that create different coloured and different shaped crystals.
