Homemade Colour Volcanoes – Preschool Science Experiment

Sharing with you today a nice and simple kids science experiment. This is a really fun activity that toddlers upward can get stuck into, I loved this one! You only need a few basic ingredients and the results are totally worth it.

If you prep it right your clean up should also be minimal so it’s a win win; fun for the children and not too much clean up for the parents.


  • Cup/Glass
  • Water
  • Bicarbonate of Soda/Baking Soda
  • Washing up Liquid
  • Coloured Paint
  • Glitter
  • Vinegar


  1. First get your space ready. Using either a tuff tray/plastic box/just the ground as long as your happy to get these ingredients on (they will most likely wash away) to make you volcanoes.
  2. I filled some bowls/jugs with all the ingredients needed so they were easily accessible.
  3. Fill you cup half with water.
  4. Spoon in 3-4 Tablespoons of Bicarbonate of Soda.
  5. 1 Teaspoon of Washing up Liquid. Stir these together.
  6. Squeeze in a few blobs of your desired paint colour, use multiple colours and add some glitter to! Stir these in if you want to or leave as is to get different colours.
  7. Your final ingredient to make the colour volcano erupt is 1 cup of vinegar.
  8. Pour in the vinegar and watch the results!

There we have a super simple kids colour volcano recipe that you can get stuck into and enjoy! Amelia loved this activity and was so excited choosing different colours for the volcanoes, adding the glitter and then watching it fizz. Obviously the more bicarb and vinegar you add the bigger the fizz we varied ours but even so it was so satisfying to watch.


This is a great preschool activity and as children get older you can discuss why the ingredients when combined make the colour volcanoes fizz. Try out different colour combinations and enjoy!

Do let me know if you try this one out!
