Volcano Experiment
🌋 "Volcanic Eruption Experiment" In this experiment, we recreated a miniature volcanic eruption using an Erlenmeyer flask as our volcano. By combining baking soda (a base) and vinegar (an acid), we produced carbon dioxide gas (CO₂). The bubbling and foaming effect that replicates real lava flow! To make it more visually exciting, we added food coloring for color and a bit of dishwashing liquid to enhance the foamy eruption. #SCIENTIAmazing ⚠️ Disclaimer: Performed under controlled conditions. �
