What is better for Mentos Coke or Diet Coke?

Believe it or not, research scientists have actually concluded that Diet Coke produces the best stream of flying soda (much to the joy of the Mentos Experiment enthusiasts).

How does a Coke and Mentos Rocket Work?

Why does the Coke and Mento Rocket work? There are several theories, but it’s thought that the many small pores on the candy’s surface speed up the release of carbon dioxide (CO2) gas from the soda as they give a larger surface area for the reaction to occur over, causing foam to erupt at a super fast rate.

Why does Diet Coke work best with Mentos?

In the Diet Coke bottle the Mentos candy provides a rough surface that allows the bonds between the carbon dioxide gas and water to break more easily, helping to create carbon dioxide bubbles. Because Mentos candies are rather dense, they sink rapidly through the liquid, causing a fast, large eruption.

Why does Diet Coke work the best with Mentos?

A Mentos mint added to a bottle of Diet Coke produces a large fountain of fizz. Diet Coke is best for this activity because the caffeine, sodium benzoate and aspartame each contribute to the Mentos reaction.

What is the effect of Mentos on Diet Coke?

The physical characteristics of Mentos (surface roughness) have the effect of drastically reducing the activation energy for carbon dioxide bubble formation, so that the nucleation rate becomes exceedingly high. The activation energy for the release of carbon dioxide from Diet Coke by addition of Mentos has been found to be 25 kJ mol −1 .

Why does Diet Coke react to Mentos?

As to why diet sodas like Diet Coke produce such a bigger reaction, it’s because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. 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.

What is the purpose of the Diet Coke and Mentos experiment?

Mentos and Diet Coke Experiment. Carbon dioxide is the chemical compound that consists of two oxygen atoms bonded to a carbon atom. Carbon dioxide creates the bubbles in soda. The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke.
