Bubble Bomb

What's Happening?

The bubbles in the Bubble Bomb are filled with carbon dioxide, a gas that forms when the vinegar (an acid) reacts with the baking soda (a base).
If you've ever made a cake, you've already done some experimenting with the bubbles that come from an acid-base reaction. Most cakes rise because of bubbles in their batter. Those bubbles, like the ones in the Bubble Bomb, are created by the chemical reaction of an acid and a base.
