Mix all the ingredients (no cooking required) in a mixer (I use my KitchenAid or my Bosch). Knead like you would your bread and store in plastic bags or airtight jars. You can add more food coloring if the dry unsweetened drink mixes don’t give you the color you want. I like my play dough “bright” in color so I sometimes need additional food coloring. I pull out chunks of the dough and put them in separate bowls and add the food coloring to the dough in the mixer. I keep adding coloring until I achieve the color I like. You do not have to use any unsweetened drink mixes. The kids think it's really awesome if the play dough has a little grape, pink lemonade, lime, or fruit punch fragrance. It's optional, just so you know.
