What a fun and very scientific activity that I was able to use while discussing crystals with my children! I really appreciate the price and the matter of how many in and how adorable that my children will have these Crystals! Very educational, the crystal growth Makes it look like a real tree. The three different colors are awesome. I was surprised of the size of them, considering I thought they would be bigger, but the fact that you get the extra crystal in it at the bottom is awesome.

I was surprised how fast the crystals grew. The crystals grew this big in just 10 hours. I took then out because I didn't want them to start getting bigger than the width of the cup. So pretty and the instructions were clear and easy to follow. Worth the price for a science lesson and a lovely end product. I used boiling water from a kettle, not just hot water from the tap, and I think that was the reason they grew so well.

This was a fun project to make with my daughter. The blue and pink crystal came out great, the yellow one was really thin and broke apart.

Easy to do really cute it is kinda small but with children they enjoyed it.

This is a fun, stem oriented project kids. They had so much making these crystals and kept asking questions on the science behind it.

Greatly appreciated the product.

easy to understand good results

While filling up the enclosed plastic cup with boiled hot water the blue powder and hot water l leaked from a Crack in the bottom of a cup staining g my wooden table and nearly scalding my 4 year oldGrandson. Thank God there were 2 adults helping out it would have been a much more disastrous event. I would like reimbursement but no one answers the phone# on the side of the box!!
