Make sure you buy the Crayola Model Magic Clay and not the Air Dry Clay. They are very different and it will not work with regular air dry clay (trust me!). Add a little amount of clay (as pictured below) and fold over your slime and knead it into the slime. Keep kneading until your slime is colored and the clay is thoroughly mixed. The reason it’s not that stretchy is from the Model Magic– so adding lotion and oil help to make the Model Magic stretchier and more pliable.

If it sits out too long the clay will start making it harder, so when it’s not in use we recommend sealing in an air tight container to preserve it.

Other examples of polymers are Jell-O, gum and rubber bands. Glue is also an example of a polymer. A polymer is made of long chains of polyvinyl acetate molecules. These chains slide easily between one another making the substance pourable. If you want to use white clay you can, but you will need to add coloring to the mixture.

I decided to use yellow clay so my slime would have a buttery yellow color to it without having to add any additional coloring.Glue: We prefer Elmer’s regular white glue for most of our slime recipes because it is quality PVA glue. Dollar store glue or other brands of glue may not work as well. We also like to stay away from Elmer’s Glue All or natural brands.

Always wash hands before and after use. If you notice any skin irritation discontinue use immediately. See the bottom of the post for more safety precautions.
