- STEP 1: Fill the empty 2-liter bottle halfway with the vinegar. Describe and classify the vinegar by its observable properties.
- STEP 2: Fill the balloon with baking soda. Describe and classify the baking soda by its observable properties.
- STEP 3: Carefully stretch the open end of the balloon around the neck of the 2-liter bottle.
- STEP 4: Dump the baking soda, inside the balloon, into the 2-liter bottle and observe. Did mixing the two substances result in a new substance?

When the baking soda is mixed with the vinegar, a chemical reaction happens, which creates carbon-dioxide gas. The carbon-dioxide gas fills the balloon, causing it to expand.
