The principle of volcanic eruption
Baking soda + citric acid + water will form a volcanic eruption scene, because baking soda is alkaline and citric acid is acidic. The two will react to generate a large amount of carbon dioxide gas, which is easy to decompose and overflow from the solution, forming bubbles and releasing The heat is generated, and if it reacts in a limited space, it will produce a volcanic explosion.
