Mix cornstarch and baking soda in a large bowl.

Add oil in a quarter cup at a time, stir vigorously.

Mixture will start to turn into moldable clay. If you like it more squishy, add a little more oil. For a silky texture that doesnt stick to your hands, a little less oil. Play with it as you go to find a texture you like.

Stir in food coloring and set out to play!
