For this experiment you will need; balloons, paper funnel, baking soda, vinegar, and a small clean empty bottles.
To try it, start by adding three teaspoons of baking soda to each balloon with the funnel. Next add vinegar to each bottle, fill them to about 1/3 full. Then stretch the end of the balloon over the mouth of the bottle and let the baking soda drop into the bottle. The chemical reaction should cause a gas that will blow up the balloon.
Why does that happen? The article explains it this way “The vinegar mixes with the baking soda to create a chemical reaction that produces carbon dioxide gas. The
gas then blows up the balloon.”
Very neat.
