Lemon Volcano Experiment

Yield: 0

Equipment

  • baking sheet
  • paper towels
  • sharp knife
  • kitchen knife or wooden popsicle sticks

Materials

  • 1 large lemon
  • 2 drops food coloring
  • 2 drops liquid dish soap
  • ⅛ tsp baking soda

Instructions

  • Cut the bottom off of the lemon so it can stand upright, cut the top off of the lemon to expose the inside.  Place lemon upright on a baking pan lined with paper towels.
  • Take the popsicle stick and mash up the inside of the lemon to create juice and a little well, be sure not to go too far down in the lemon with mashing it up.  You don’t want to accidently poke through the bottom and have all of the lemon juice leak out.
  • Add in 2 drops of liquid dish soap and 2 drops of food coloring.  Stir a little bit to combine with the lemon juice.
  • Add in 1/8 teaspoon of baking soda and watch the lemon erupt.  You may need to stir a little to create mass amounts of bubbles.  When the bubbles calm down you can stir more to reactivate the baking soda or you can also add a little more baking soda.
