Coke diet mentos why
You can also increase the effect by adding more surfactants to the soda when you add the Mentos, like adding a mixture of dishwasher soap and water. Diet sodas produce a bigger reaction than non-diet sodas because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will.

This is another reason Mentos works so much better than other similar confectioneries: The candies are fairly dense objects and tend to sink rapidly in the soda. Each Mentos candy has thousands of small pores on its surface which disrupt the polar attractions between water molecules, creating thousands of ideal nucleation sites for the gas molecules to congregate. Combine Diet Coke and Mentos, and the result is explosive—Diet Coke shoots out of the bottle like a miniature, sticky Old Faithful. In addition to creating viral marketing campaigns for brands like Coca-Cola, OfficeMax, and ABC Family, Grobe and Voltz also give presentations at corporate events on viral video, creativity, and innovation. Bubbles will continue to form on the porous surface and the process will repeat, creating a nice, foamy geyser. Another factor that contributes to the size of the geyser is how rapidly the object causing the foaming sinks in the soda.
The reaction is so intense, you can make a rocket propelled by the resulting geyser. Coffey and company discovered that the ingredients in the Mentos and Diet Coke and, more importantly, the structure of the Mentos, allow carbon dioxide bubbles to form extremely rapidly. In addition to that, the gum arabic and gelatin ingredients of the Mentos, combined with the potassium benzoate, sugar or (potentially) aspartame in diet sodas, also help in this process.

EepyBird explores creativity, and the ways ordinary objects can do extraordinary things. They have been featured on The Late Show with David Letterman, The Today Show, Ellen, and Mythbusters. Tonya Coffey of Appalachian State University and her physics students published a paper on the phenomenon in the American Journal of Physics.
