Change question: Why does vinegar and baking soda when mixed transform by a chemical reaction?
We want to know what it creates?

Prediction: It creates gases and a yucky smell and the cork is going to blow off the bottle and the gas
will keep out until all the liquid has disappeared.

Observations:  we saw the bottle get bigger and wider

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.
