Erupting Snow Volcanoes

Erupting Snow Volcanoes

And for our next experiment we tried Erupting Snow Volcanoes. This is a great activity for kids! I took the ingredients needed to my 3 year old daughter’s preschool yesterday and tried it out with her class of 11 kids. What a raging success!

Here’s how you do it:

  • Take 1 can of shaving cream and empty it all into a bucket. Even this was a delight for these small hands!
  • Empty 1 x 500g bicarbonate of soda into the bucket and let the little fingers mix it up. This makes the snow. It is cool to the touch and a great sensory stimulating activity!
  • Make a little mound of snow (the volcano)
  • Pour a little bit of red food colouring onto the top (this is the lava)
  • Give your child a spray bottle of vinegar, when they spray it onto the mixture it fizzes and erupts.

Try it out and let us know what you think!

  1. Great post Lynne – Thank you !

    Will definitely be strealing this idea for kids projects in future – love it !

  2. Wow! Great idea! Thanks for sharing! I will have to give them each a bucket with their own or else there will be some conflict with my two! 🙂

  3. My boys tried this yesterday. Their had so much fun, used different colours of food colouring and this project kept them busy :-). I’m definitely going to share this with my Mom, great idea for her kindergarten class
    Thanks Lynne 🙂

  4. Nadia, so glad you enjoyed it! You can also just do the snow on it’s own which my kids loved and if you want colour snow just mix in food colouring.

  5. I remember this one… we did this when i was in primary school.
    Very cool!!!

    • Oh nice Marisca, I never did this in primary school… I just found it online and thought it would be so cool to try with my kids!
