Have you ever wondered what happens inside a volcano during an eruption? 🌋 Now, you can bring the excitement of a volcano right into your home with a simple and safe experiment using baking soda and vinegar! This fun activity is perfect for kids, students, and anyone curious about science.Materials Needed :
- To create your mini volcano, you will need:
- Baking soda (2–3 tablespoons)
- Vinegar (½ cup)
- Red food coloring (optional, for realistic lava)
- Small bottle or container
- Clay, playdough, or paper mache (to build the volcano shape)
- Tray or large plate (to catch the overflow)
The baking soda is a base and the vinegar is an acid. When the acid and base combine, an endothermic reaction occurs and releases carbon dioxide. The carbon dioxide gas rushes toward the bottle opening and also causes the dish soap to foam. The gas and foam quickly fill the bottle an erupt from the top and causes a cool looking “lava flow” down the side of your volcano.
