Jacob and Kyle got moon sand for their birthday. I had never heard of it, but today with all the rain we pulled it out.
It pretty much worked just as advertised. It is pretty much sand that molds. It comes in many colors. They chose orange and blue today. It did make a mess all over thought, because it is, after all, sand, so there was some substantial cleaning afterwards. Jacob and Zachary were able to put it into a small bowl and then turn the bowl upside down and have a sand castle.
Other than that, we weren't really sure what to do with it, but they both had a ball, especially Zachary. He just kept moving it from one bowl to another. I forget how easy it is to entertain little kids.
