now were going to see when Vinson mixes the two liquids together. Are you ready Vinson. Let me put my goggles on. Pour them together. Look at that foam. The vinegar is a sideike and the baking soda is alcholine. When you mix them together it produces a chemical reaction. Carbon dioxide gas is produced by the reaction. The carbon dioxide gas combines with the soap and makes foam that oozes out of the test tube. What a great experiment. Wow, look at that foam.
