We made this wonderful play dough the other day. It came out so soft and pliable. It did get a little crumbly, so keep that in mind if you try making this. Here is the recipe.
2 cups baking soda
1 1/2 cups cornstarch
1 cup of water (add your choice of color to the water)
Mix all the ingredients together in saucepan. Bring to a boil and cook until thick. If he dough is too sticky add a little flour or cornstarch and knead.
