Lizzy has been wanting to make volcano for a while now so we finally did. We used a vase and covered it with old play dough and a salt dough mixture and let it dry. We painted it then used the recipe bellow. Here is a video of our volcano erupting.
1 tablespoon liquid dish washing soap 3 drops red food coloring 1 cup vinegar 1 1/2 cups warm water 2 tablespoons baking soda
