4M Toysmith, STEAM Powered Girls Crystal Garden, Chemistry DIY Stem Toy, for Girls Ages 10+

This crystal set was simple to use. Some of the crystals came out looking like the images on the box. Others, not so much, but what do you expect when you're creating crystals in a hexagonal bowl rather than nature? If I did it again, I would go lighter on the red coloring. It tells you how much to put into the cup and how to mix the colors to get different ones, but I ended up with 3 red crystals that were supposed to be 1 each of red, pink and purple, so...Just know if you want purple use less red and more blue than it actually says, and if you want pink, use more white and less red than it says.

Didn’t work! My son used a different kit and got great results. This one was a flop and my daughter is so bummed :(
