Fluorescent Deluxe Rocks Science Kit
My children LOVE geology, so I was really excited to buy them this set of rocks for a science themed birthday party. I was a little bit disappointed, though, because not all of the rocks provided actually react to the UV light. There was one that was really cool. It glowed orange for some time after having the UV pen removed from it. Others didn't have any color at all. My kids are still really happy with the set, having added it now to their general "rock collection". I just feel that the other set (Amazing Rock Science Kit) did a better job of delivering on what it promised. If you're trying to choose between the two, I would go with that one over this.
