sdaymol Crystal Growing Kit for Kids - 4 Colors Hedgehog to Grow Fast in (24H),Science Experiments Learning & Educational Toys,Science Kits for Kids Age 8-12 STEM Project Gifts for Boys & Girls 6+

Great stocking stuffer! I got my granddaughters each one for Christmas. They enjoyed watching them grow and now they have an honored place on the bookshelf!

Fun and easy to useI like the finished project

Bought a 4 pack but only 2 made crystals. I kept them in the solution for 4 days when it says it only needs 24 hours. Kids are not able to place the hedgehogs in themselves or take them out due to the chemicals used in this kit per the instructions. When removing the hedgehogs, even with tongs, several crystals broke because they are so fragile.

Pros crystals grow great very cute an easy to do.Cons one of the tubs came broken

Best crystal growing kit we have bought because it comes with a container you can display. All the other kits, the growing containers were just plastic cups and you cannot remove the crystals to keep or display without them breaking. This kit was so exciting for my science loving son so he could put his hedgehog crystals on his shelf. Highly recommend. Grew fast and looks just like the display photo.

I bought this as a Christmas gift for my son. He loves hedgehogs and science experiments so overall we thought it would be perfect. The issue is that both times we tried to do it, the end result was not a hedgehog crystal, it was a bowl of mush. We were disappointed.

This was a fun science experiment to do with my son.You do have to boil water, and you have to stir for about 5 minutes for each hedgehog. My son said he thought his arm was going to fall off from all of the stirring. I assured him his arm would not fall off.The instructions implied the hedgehog would be fully grown after a two days, but I left ours in for a couple additional days. The green hedgehog grew faster than the blue hedgehog. So I left the blue hedgehog in an additional day longer than the green one. I probably could have left them in the fluid even longer, but we were too excited and wanted to see what they look like after 4 days.The crystals are fragile, The hedgehogs can't really be handled because when you touch the crystals they do break off.You will need gloves to take the hedgehogs out of the fluid, the fluid will stain your hands. Gloves are not included.Overall were very pleased with this experiment!
