You can find this recipe on a lot of different blogs out there, when I first saw the idea I knew I had to make some for Hudson. He loves it! All you do is mix 1 cup of water with 1 cup of cornstarch. Then pour it into muffin tins or small cups. Then add food coloring to make the colors you would like. I used the Wilton food coloring gel and it made some very bright and vibrant colors!I found my recipe here at Smashed Peas and Carrots.
