Diet Coke and Mentos eruption

When you mix Diet Coke with Mentos, it makes a big fizzy and bubbly explosion! This is because Diet Coke has a lot of carbon dioxide gas inside it that is trying to escape. When you put Mentos candy into the Diet Coke, it creates lots of little bubbles on the surface of the candy. These bubbles help the carbon dioxide gas escape even faster! This creates a big explosion of Diet Coke shooting out of the bottle. It's like a volcano erupting with lots of molten hot lava but instead of lava, it's Diet Coke exploding out of the bottle. It's really cool to watch, but it's important to never try this experiment at home without adult supervision and safety gear because it can be dangerous.
