Measure 60 milliliters of vinegar and pour into the soda bottle. Measure out 7 grams of baking soda and place it into the balloon. Put the neck of the balloon over the top of the bottle, being careful not to let the baking soda fall into the vinegar. Tie a string around the necks of the balloon and the bottle to keep the balloon from "popping off." ................
