To start, it should be noted that it’s not just Diet Coke and Mentos that “react”; other carbonated beverages will also readily respond to the addition of Mentos. What’s going on here is that Mentos has thousands of small pores on its surface disrupting the polar attractions between the water molecules, creating thousands of ideal nucleation sites for the gas molecules in the drink to congregate. In non-sciency terms, basically, this porous surface creates a lot of bubble growth sites, allowing the carbon dioxide bubbles to rapidly form on the surface of the Mentos. If you use a smooth surfaced Mentos, you won’t get nearly the reaction.
