Baking Soda and Vinegar Experiment Worksheet
What you do (Acid + base → gas): 1. Pour vinegar into the plastic bottle, standing on a tray. 2. Spoon two teaspoons of baking soda into the balloon. 3. Stretch the balloon over the bottle’s mouth, letting it hang to the side. 4. Lift the balloon so the soda drops in, and keep faces back.
