Lemon Volcano


All experiments should be performed with adult supervision.

Appropriate safety wear, such as googles and gloves, should be worn.

  1. Begin by slicing the bottom and the top off of your lemon. It should sit upright and flat, so we can pour in scientifically magic ingredients.
  2. Next, mash-up the inside of the lemon with your craft stick: the more juice you make by mashing, the better. You want a puddle of juice to form in the top.
  3. Now we add ingredients to the lemon. Add 3 to 4 drops of food coloring, then 2 to 3 drops of dish soap.
  4. Mix the soap, food coloring, and lemon juice together with your craft stick. Continue mixing until the color changes.
  5. Then, add two teaspoons of baking soda and keep mashing the mixture into your lemon using the craft stick.
  6. Add three more teaspoons of baking soda and more lemon juice, then watch the reaction. You should be seeing a citric eruption.
  7. You created an acid-base reaction from citric acid and sodium bicarbonate. Scientists study this to prevent wear and tear on engines. The Lemon Volcano experiment is complete!
