A Soda FountainMentos contains a chemical known as arabic gum (this is the ingredient that makes the mint "chewy"). This ingredient causes the surface tension of the water molecules to break even more easily, releasing carbon dioxide gas.

However, this is not the primary reason for the release of carbon dioxide gas . If you look at a Mentos with a powerful microscope, you will see that it has a very rough surface, that looks somewhat like pumice. This bumpy surface attracts the carbon dioxide in the Diet Coke to the point where a bubble forms, at which point it's released and rises to the top of the coke. Multiply this by a couple million times around the entire Mentos, and you have a fountain!
