The Scientific Explorer's Ultimate Crystal Growining Science KitScientific Explorer's Ultimate Crystal Growing Science Kitis a great kit for variety and interaction. I got this for my 8 year old grandson who is a real science 'explorer' and he just loved it. He was into the kit and growing crystals before you could say Jack Robinson. (Okay, that's an old saying!) He loved that there were so many to grow and all the varieties kept him interested. He is a real fan of science experiments and this kit just kept him involved and enthused through all of the kinds of crystals he was growing. It is a real value for the price and I know that any child interested in science will like it.
