Change question: Why does vinegar and baking soda when mixed transform by a

Conclusion/ Answer to your question:


The chemical with vinegar and baking soda is gases that full the plastic
bottle with air that make the bottle harder and harder. in side and makes
the bottle wider and wider so the vinegar  and baking soda makes
a chemical that will make the bottle huge.
