Please don't try this at home. So my science class did an experiment with yeast and sugar, and when the yeast rose in the cup with more sugar, I had an idea. If yeast + sugar = rise, baking soda + vinegar = boom, I could add those together for something larger. So then I made this project and decided to add a nuclear bomb... for some reason. chaos. Also, yes the capacity for all of them is gallons.
