The chemical reaction you created was an acid-base reaction! Which was one the acid and which one was the base?

The acid was the vinegar and the base was the baking soda.

Baking soda is a compound known as sodium bicarbonate, and vinegar is a solution that has acetic acid. When the baking soda and vinegar are mixed, the hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda, which creates the movement of the bubbles of the rice you see when the vinegar is added. Both the vinegar and baking soda formed a gas. Because the gas bubbles do not like to be stuck in liquid, the bubbles floated up and brought the rice with them.

Future Questions:
What would happen if you used another type of rice?
What if you swapped the amount of vinegar and baking soda? Will this affect how much the rice dances? Try it out!
