Small funnel or a small piece of paper rolled up in a funnel shape
Baking soda
Vinegar
Small clean empty bottle

Directions

Using the funnel, add 3 teaspoons of baking soda to each balloon.

Fill each bottle 1/3 full with vinegar

Without dropping in the baking soda, fit the balloon over the bottle opening

Hold up the balloon and let the baking soda fall into the vinegar

Watch as the baking soda mixes with the vinegar to make carbon dioxide gas and blow up the balloon
