HearthSong Grow Your Own Crystals Kit-Hedgehog, 3”L x 1”W Figurine Base, Adult Supervision Required, Spring Green

It came out perfect! We followed the directions to the letter, let the water boil about a minute (whistling teapot), then after two days soaking, we got a perfectly spikey crystal hedgehog! We used a flashlight to monitor crystal growth while it was submerged, because the liquid is so dark, even the flashlight on my phone couldn't shine all the way through, but you could see crystals sparkling. Crystals also grew on its face, but they cleaned off easily. They also grew as a carpet all over the floor of the container. I don't know what to do with all this pretty blue crystal, but I love it!

this was bought to give as a giftit was easy to order and quick to ship.

We followed the instructions exactly, plus it was not our first time using a crystal growing kit, so we knew what to do.It worked, but the crystals didn’t grow as long as in the picture. Also, shortly after removing it from the water, a greenish layer started growing over some of the crystal, making them a fuzzy green.Overall it was a fun experience and the end result looks nice, but I’m giving it less than 5 stars because it didn’t come out like the pictures.

Grandchild liked it very much. Exactly what she wanted

I got this for my 5yo daughter for her “crystal” themed birthday. She was very excited, though there wasn’t that much for her to do since she’s young so I did most of the tasks: Pour poisonous crystal mixture into cup, add boiling water, drop hedgehog in, wait 48 hours. You can see from the pic what it looks like after 48 hours. Neat to see the science happening, but the final result doesn’t match the advertised pic. I’d buy it again… it wasn’t too expensive. Since it’s apparently very poisonous, I threw it away after a couple weeks.

I was REALLLY looking forward to doing this little project. Unfortunately, it didn't work. I followed all of the instructions, but even after leaving it for a whole week, no crystals ever grew. I honestly think it's because there's too much powder provided, but not enough room in the growth container for all of the liquid to fit. Even though I mixed it very well, I still had to pour a decent amount out so it would fit in the container. I've night this from another maker before at our local museum and had the same problem. Sad because it looked like a cool project.

I bought another brand previously and it did not work. This works! It’s super easy and the crystals were pretty long in just a few hours. I highly recommend this product.

The bowl that the hedgehog sat in came cracked and couldn't hold water. It totally failed.
