This is a great fun experiment the kids will love and it uses ingredients you’ll probably have in your pantry.

Make your own volcano

What you’ll need:

  • A plastic bottle
  • 6 cups of flour
  • 2 cups of salt
  • 4 tablespoons of oil
  • water
  • 2 tablespoons of baking soda
  • white vinegar
  • food colouring
  • dishwashing liquid.


  1. Mix the flour, salt, oil and 2 cups of water in a bowl to make the dough.
  2. Place the empty bottle on a tray.
  3. Sculpt the dough around the bottle to create a volcano shape, leaving top of bottle clear.
  4. Fill the bottle up with warm water and a few drops of food colouring.
  5. Add 4 drops of dish liquid and the baking soda to the water.
  6. Slowly pour in the vinegar and the volcano will erupt.

I love the idea of getting the kids sculpting and making their own volcano as well as getting it to erupt.

You could easily just do the experiment in a bottle without the dough if you wish. I also like to do this outside and then the mess doesn’t matter and the kids make a whole game around it.
