Cassandra's review- I am going to tell you that this is a huge mess and I mean big, it gets color on everything and in the air and on the grass and on the cars--so be careful where you throw your "party" . Is it fun? Yes. Is it hard to clean up? Mostly yes, but if you do this like in the woods or somewhere no one cares about getting mess all over, then you are only cleaning up yourself and everything you brought with you. So unless you cannot fathom being covered in color, this may be a huge party success. At first I had no idea why I was receiving bags of 5 lb cornstarch colored powder each, but after reading all about this and seeing the games that could be done with it, I would say that any children would have a ball, just be sure to supervise your kids because even though this is non-toxic, it really does get everywhere. I would probably only throw this party once in a lifetime, but more flexible people would probably do it way more often.
