Snow volcano science experiment directions

STEP 1: Get your supplies ready

Before heading out into the snow make sure you have all your supplies ready. This science experiment is so much fun that the kids will want to do it again and again. I'd recommend having lots of baking soda and vinegar ready! 

STEP 2: Build a snow volcano! 

Before you can start this fun snow volcano science experiment you need to build a volcano from snow. Pile some snow into a volcano shape and secure a small tube (or bottle) in the centre of it. Fill the tube with a drop of washing up liquid (dish soap), lots of baking soda and a couple of drops of colouring.

STEP 3: Time for the snow volcano science experiment

Now you have your snow volcano set up the fun begins! Take a bottle of white vinegar and squirt it into the tube filled with baking soda. As the vinegar reacts with the baking soda your volcano will erupt! The washing up liquid makes the volcano eruptions extra foamy.

Don't stop at making just one snow volcano, make a whole collection of snow volcanoes! We chose to add a different colour to each of our volcanoes. 

We had so much fun squirting the volcanoes with vinegar and watching the colours erupt.

You are going to have so much fun with this snow volcano science experiment! I think my two could have made baking soda and vinegar volcoanoes all day! If you want to try more baking soda science experiments take a look at our fizzy rainbow and our exploding magic potions for kids.

So, if you have snow right now make the most of it with this fun snow volcano science experiment. If not, save this fun idea for when you do! Honestly, kids of all ages from toddlers and preschoolers up to much older kids will love making a baking soda and vinegar volcano. We would love you to share with us any photos if you make your own snow volcano!
