Query: TERRIBLE STUFF!

We were given this as a gift for Christmas and I'm sorry but its not something I would ever give to a friend. Its EXTREMELY messy and not appropriate for 3 year olds (especially active hyper boys like I have). The sand gets everywhere. At least with playdough you could use it to pick up the rest of its stray parts by sticking it together. Moon sand sticks to nothing with means its goes EVERYWHERE. Most of it is going to end up in the vacuum after the first use. Also, the colors get all mixed together VERY easily because you can't stick them together. Its impossible to make what they show in the picture without being at least 10 years old and VERY patient! This is definitely at toy that requires DIRECT adult supervision if you don't want to be feeling "the sand between your toes" for days to come!
