Self Inflating Balloon
The reaction between the lemon juice and the baking soda solution is one that creates a great deal of carbon dioxide gas. As the lemon juice and baking soda react, more and more of the gas is given off. As the gas accumulates, the balloon becomes bigger and bigger. In fact, if you added ¼ cup more of the baking soda solution, the balloon could explode if it doesn’t fly off of the water bottle!
1. Would this reaction work with a different acid? Vinegar?
2. Would this reaction work with a different CO2 source?
3. Can this reaction also be done with fermentation?
