Stuck at home on a rainy afternoon? Bored? Don't
worry, I have a cool experiment you can do that will make being inside as

Caution: Do not try any of these experiments without adult
supervision! If you are over eighteen, then why are you stuck at
home? Go to a movie!

baking soda falls into the vinegar at the bottom of the bottle.
