======Blowing Up a Balloon with Baking Soda and Vinegar====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Self-Inflating Balloons, Baking Soda and Vinegar Balloons ====Summary==== {{$demo.summary}} ====Procedure==== - Use a funnel to add baking soda into a balloon. - Partly fill a plastic water or soda bottle with vinegar. - Stretch the balloon opening over the bottle’s mouth, keeping the baking soda inside the balloon. - Lift the balloon upright so the baking soda falls into the vinegar. - Observe the fizzing reaction and watch as the balloon inflates with carbon dioxide gas. ====Links==== Baking Soda + Vinegar Balloon Experiment! - Education.com: {{youtube>Uy_y3ml1VeU?}}\\ 📄 Baking Soda and Vinegar Balloons - One Little Project: [[https://onelittleproject.com/baking-soda-and-vinegar-balloons/]]\\ ====Variations==== * Adjust the amounts of vinegar and baking soda to test how gas production changes. * Add food coloring to the vinegar for a colorful reaction. * Compare balloons filled with carbon dioxide to those filled with air - drop them and see which falls faster. ====Safety Precautions==== * Perform the experiment over a sink or tray to catch spills and foam. * Do not overfill with baking soda and vinegar, as the balloon may pop. * Avoid touching your eyes after handling vinegar or baking soda. Wash hands afterward. * Use supervision with younger children handling balloons and liquids. ====Questions to Consider==== * What type of chemical reaction occurs between vinegar and baking soda? * What gas is produced, and how do you know? * Why does the balloon inflate without anyone blowing into it? * Why does a carbon dioxide–filled balloon fall faster than an air-filled balloon? * How could you design an experiment to measure the exact amount of gas produced?
