Volcano Pumpkin Experiment


What you will need:

  • A small pumpkin with the top cut off and the inside hollowed out.
  • Vinegar.
  • Liquid dish soap.
  • Food colouring.
  • Baking Soda.
  • Large bowl, casserole dish etc. (optional).
  • Wooden spoon.
  • Tablespoon.


  • First, cut the top off your pumpkin and scoop out the inside.
  • Next, place your pumpkin in a large bowl, casserole dish etc. (to catch any mess or you can do the activity outside)
  • Then, fill half the pumpkin with vinegar.
  • After that, add in a squirt of dish soap (the more you add the more foam) and a few drops of food colouring.
  • Mix this all together using your wooden spoon.
  • Ask your child what they think might happen.
  • Finally, add in a tablespoon of baking soda. Keep adding a tablespoon for more of an ‘explosion’.
