Try using cold water or hot water. The first time you tried this, you mixed the vinegar with water. Try doing the experiment again with just vinegar. Any baked goods that rise rely on carbon dioxide bubbles to get the job done. You can make these bubbles either by using yeast or by using the acid-base reaction like you did in the experiment.
Yeast is a one-celled fungus which converts sugar to carbon dioxide gas.
Because this process takes a while, bakers use yeast in doughs that they leave alone for several hours. Another method that cooks use to make something rise is a combination of baking soda and an acidic ingredient, like orange juice or buttermilk. This is the same kind of chemical reaction that took place in your bubble bomb. Next time someone you know is baking, check the recipe to see if you can figure out what ingredients make the bubbles that make the cake or bread or cookies rise.
