Who doesn’t love mixing up a bubbly combination of baking soda and vinegar!?

Add the joy of building and playing in the snow  = some very happy kids!

Grab a pitcher or bucket and place it into the snow.

Build a mountain of snow around it. Leaving just a hole at the top uncovered.

Grab a container of baking soda and a container of vinegar.

Add colour to the vinegar.

Dump the baking soda into the hole (into the pitcher) …

And then add the coloured vinegar and watch!

To Add

• Encourage the kids to predict what will happen
• Use a variety of colours. Blend and mix colours.
• Build a Giant Snow-cano
• Make it a race – set up a few snow-canos and watch to see which one will erupt first
• Make predictions about what will happen to the ‘lava’ if left in the snow
• Add lightweight objects – such as pom-poms or buttons – will they stay in the container? Or bubble over the side?
• Leave the vinegar outside … Does it freeze? If frozen and added to the baking soda… Will it still bubble?

And PLEASE share your experience with me! I love hearing your stories and seeing your photos.
