- Step 5: When you are ready... tip the balloon so the baking soda pours into the bottle

Vinegar contains ~5% acetic acid (CH3CO2H aka CH3COOH or AcOH in short) which reacts with a component in the baking soda, sodium bicarbonate (NaHCO3) to form carbonic acid (H2CO3). But carbonic acid is very instable and, in a decomposition reaction, forms carbon dioxide (CO2) and water (H2O). CO2 is a gas, meaning that the volume of the CO2 is much bigger than that of baking soda or vinegar, causing the CO2 to flow into the balloon.
