Combine two cups of water, four tbsp. of cooking oil, two cups of salt and six cups of flour into a large bowl.
Add a few drops of orange and green food coloring to your playdough mixture.
Mix the ingredients together using your hands until the mixture is smooth. Reserve this playdough mixture to form the volcano. Wash your hands with soap and water to avoid staining from the food coloring.
Stand a small water bottle upright. Place the homemade dough around the bottle structure. Shape the surrounding dough into the shape of a volcano. Allow the shape to dry thoroughly overnight.
Pour 60 milliliters of water, a few drops of detergent, orange food coloring and 1/4 cup of vinegar into the bottom of the water bottle.
Place one tbsp. of baking soda into a tissue. Drop the tissue to the bottom of the bottle and watch the explosion begin.
