Balloon Blow Up
INGREDIENTS
- Baking Soda
- Vinegar
- Balloon
- Empty 2 Liter Bottle
INSTRUCTIONS
STEP 1: Fill the empty 2 liter bottle half of the way 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 the balloon to expand.
