Great choice, Junior Scientist! Today we're doing the "Baking Soda & Vinegar Volcano" experiment. Let me explain what we'll discover together. Baking soda (a base) and vinegar (an acid) react to make carbon dioxide gas. The gas bubbles up through the liquid and soap, creating an eruption — just like a volcano!
Place your cup on a tray or outside table to catch the fizz.
