Corn Starch Dough Recipe- This is just the coolest stuff ever, sadly it only retains its amazing original texture for a day or so. The recipe isn't large so if you have more than 2 kids playing make a double batch.
White dough: cup cornstarch 1 cup baking soda cup water _Bake at 175 degrees F for minutes. Then flip over and bake an additional minutes, or until all ornaments are hard. Let cool then spray with a clear protective coating (Krylon matte finish).
