Once you have put the volcano together, simply pour in the baking soda, then the vinegar, and you will have an impressive volcanic eruption in your very own home! You can add some red colour food dye to make it look more authentic. If you add the dye, add this to the baking soda before you pour in the vinegar.
How does it work?
The vinegar is an acid, and the baking soda is a base. Mixing them together creates a reaction between the two that produces carbon dioxide, which is what causes the fizzing eruption of your volcano!
