The paint on the inside and outside of your volcano should be completely dry before you make the volcano erupt. Let it dry overnight to be sure it is dry. Otherwise, the paint may run when you add the eruption ingredients.  Place the volcano out of the reach of pets, such as up on a high shelf or closed room. You can touch the paint to see if it is dry. It will feel tacky if it is wet and smooth if it is dry.
