Are you running out of ideas to entertain the troops at home? I used to do this little science experiment with Lucas when he was much younger and he loved it so much that I thought I would share with you all.

Most of these ingredients you are likely to already have lying around the house. Have lots of fun and feel free to share pictures of your creations with us on Insta or Facebook, we’d love to see them.

What you’ll need:

Soup can or small soda bottle with the top cut off

Green Goddess Premium White Vinegar

Green Goddess Premium Baking Soda


Natural red food colouring

2 cups salt

4 tbsp cooking oil

6 cups of flour

2 cups of water

How to make it:

First make the ‘cone’ of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (more water may be added if needed).

Place the can on the ground outside or on a paper plate or tray if inside. Build the volcano around the can.

Fill the can 1/2 to 3/4 full with vinegar. Add a few drops of red food colouring, then add a spoonful of baking soda.

Watch the lava flow down the sides of the volcano as the chemical reaction between the acid and the baking soda occurs.

Repeat as long as the vinegar and baking soda lasts.
