I found this idea at a local playgroup. I had bought oats instead of instant oatmeal for a recipe, and I didn't know what I was I going to use the oats for. When I saw this, I thought this would work out great since I have a whole container of oats in the pantry. I didn't use a lot of oats that today because it was suppose to rain. Not only is it fun for the little ones, the oats give them a different texture to feel.
