Select either recipe (baking soda, cornstarch & baby oil VS flour and baby oil). Put ingredients in a bowl, stir, knead, repeat until blended well. If you would optionally like to add food coloring, add this in and stir into the baby oil before adding to the dry ingredients.
For a smaller batch the ratio is as follows:
For the flour/baby oil option:
For every 1 C of flour add 2 Tablespoons of baby oil
For the baking soda/cornstarch/baby oil option:
For every 3/4 c of baking soda use 3/4 cup of cornstarch and 1/2 cup of baby oil.
