"My 8 year old daughter and my 6 year old son loved the goo. I had them pour it on a deep plate and they played with it for a good half hour. they still play with it from time to time. Just make sure to not spill it on a fabric or carpet. It is hard to clean on those surfaces. Keep it in the kitchen limits where it is easy to wipe if spills. Make sure to supervise them while playing."
