How to blow up a balloon with baking soda and vinegar
Pour a little vinegar into a plastic bottle.
Choose a plastic water bottle, or another bottle with a narrow neck. Pour 1-2 inches (2.5-5 cm) of vinegar into the bottle, using a funnel if you have one.

Available choices:
(a). Use white vinegar, also called distilled vinegar, for the best result. You can try this with any kind of vinegar, but the inflation might take longer or require more vinegar to work.
(b). For convenience, you can use a wooden stick or a small bowl to pour the vinegar in. This will keep the bottle from flying away as you blow.
(c). The vinegar helps to ensure proper airflow so that you can actually blow air through the balloon while holding it up in the air. Shake the bottle to incorporate the vinegar.
(d). A standard liter of vinegar is 8 ounces. If you are using a smaller bottle, use 12 ounces.
Answer:
(a).
