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!

Great post Lynne – Thank you !
Will definitely be strealing this idea for kids projects in future – love it !
Enjoy, loads of fun.
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! 🙂
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 🙂
Glad you enjoyed it Nadia, next time try the slime! Keeps them busy for even longer 🙂
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.
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!
