Balloons filled with helium are a common sight at parties and celebrations, but what do you do when you don’t have access to helium? Fortunately, there are several ways to blow up balloons without helium.
One method is to use a mixture of baking soda and vinegar. To do this, you will need a balloon, a funnel, a bottle, baking soda, and vinegar. First, put a funnel in the neck of the bottle. Then, add 2 tablespoons of baking soda to the balloon and insert the balloon over the funnel. Finally, add 1/4 cup of vinegar to the bottle and watch as the balloon inflates. The chemical reaction between the baking soda and vinegar creates carbon dioxide gas, which fills the balloon.
