How To Make A Lemon Volcano?

Creating a lemon volcano is a fun and exciting science experiment that is sure to entertain and educate both kids and adults. This experiment demonstrates the reaction between an acid (the lemon juice) and a base (baking soda) to produce a fizzy eruption. Here’s how you can make your own lemon volcano:

Materials Needed:

  • 1 lemon
  • Baking soda
  • Food coloring (optional)
  • Dish soap (optional)
  • A knife
  • A spoon


  1. 1. Cut the lemon in half horizontally, so that you have two equal halves.
  2. 2. Squeeze the lemon halves slightly to release some of the juice, but be careful not to squeeze out all of the juice.
  3. 3. If desired, add a few drops of food coloring to the lemon juice to make your volcano more colorful.
  4. 4. Add a few drops of dish soap to the lemon juice. The dish soap will help create more foam in the eruption.
  5. 5. Sprinkle a generous amount of baking soda onto the lemon juice. You should see an immediate fizzing reaction as the acid and base react.
  6. 6. To make the eruption more dramatic, you can add more baking soda as needed.


When you mix the lemon juice (acid) with the baking soda (base), a chemical reaction occurs that produces carbon dioxide gas. This gas is what creates the fizzing eruption that you see. The addition of dish soap helps to create more foam by trapping the gas bubbles.

Now that you know how to make a lemon volcano, you can impress your friends and family with this simple and entertaining science experiment. Have fun experimenting and learning about the wonderful world of chemistry!
