See how to make a vinegar and baking soda bomb! Fill the bottle with as much vinegar as you want, then take a napkin or paper towel and pour the baking soda all over it. After you're done with that, roll the paper towel on the ends so the baking soda won't fall out, then put it inside the plastic bottle and quickly put the cap on. Now just throw it in the air and watch as it explodes all over the place. That's it... the vinegar and baking soda bomb.
