In this experiment, kids will make their own volcano and learn how they work. Below are all of the steps and materials you will need.


  • Flour
  • Salt
  • Cooking oil
  • Baking soda
  • Vinegar
  • Dish soap
  • Food coloring


  1. Next mix 6 cups of flour, one cup of salt, 4 tablespoons of cooking oil and warm water. (Tip: Mix the water in slowly so the consistency stays firm and not soupy.)
  2. Stand the soda bottle in the middle of the dough mix, and mold the dough around it into a volcano shape.
  3. Next fill the bottle a little more than halfway with water, red food coloring, a few drops of dish soap, and two tablespoons of baking soda.
  4. Slowly pour vinegar into the bottle and watch the eruption. (Tip: You may want to go outside for this part.)

The pressure inside of the bottle builds up because of a chemical reaction, and the same things happens inside of a volcano. The explosivity of an eruption depends on the composition of the magma inside of the volcano. If it’s thicker then gases can’t escape as easily and it explodes more violently.
