Volcanic Eruption

Please take care when conducting this science experiment. Keep children far back and ensure that you use appropriate protective equipment. This is our second volcanic eruption experiment. You can find our first one here:


The ingredients you will need for this volcanic eruption are:

  • a tablespoon of dry yeast
  • 12% peroxide
  • 3/4 cup of warm water
  • food colouring
  • plastic bottle
  • 2 cups
  • spoon
  • gloves
  • dish soap

First, fill a cup 3/4 of the way with the peroxide and pour into the bottle. Add a squirt of dish soap and a few drops of food colouring. Add the yeast to the warm water and stir until dissolved. Then add to the mixture. Give a gentle shake to start the eruption.

Here’s our video footage of the experiment:
