The Science Behind this Activity

Vinegar is an acid and baking soda is a base. When an acid mixes with a base, you get a reaction!

When vinegar and baking soda react, they create carbon dioxide gas, water and sodium acetate, which makes bubbles and a fizzy reactions.

This activity is a fun way to show kids that when liquids and solids react they can form a gas and a liquid. You can read more about this chemical reaction over at Science Sparks.
