Ingredients
Method
Preparation
- Pour a small amount of vinegar into the plastic bottles, about one-third full.
- If using food coloring, add a few drops to the vinegar.
- Use a funnel to carefully fill the balloons with baking soda, about two tablespoons per balloon.
- Stretch the open end of the balloon around the neck of the bottle, ensuring the baking soda doesn’t fall in just yet.
- When you’re ready, lift the balloon to mix the baking soda with the vinegar and step back to watch the magic as the balloon inflates and pops!
Notes
Consider pairing the experiment with lemonade or iced tea. Store unused balloons in a cool, dry place.
