Bottle-Top Volcano
Professor O will help you learn: A chemical reaction: an acid (vinegar) and a base (baking soda) make carbon dioxide gas, which is the fizzy foam.
⚠️ No heat or sharp tools needed. Vinegar can sting eyes, so keep it away from faces and wash hands after. Work on a tray or outdoors to catch the foam.
