What happans if you put Mentos in 7 up?

Mentos and 7 Up: Diet Coke and Mentos are two of the most popular combinations in the Diet Coke and Mentos experiment, which demonstrates a nucleation reaction that causes foam to erupt from the bottle. This is because the gelatin in the Mentos and the aspartame in the Diet Coke react to form a polymer that traps carbon dioxide gas bubbles. The nucleation process leads to the rapid expansion of the carbon dioxide bubbles, creating a foam that can erupt from the bottle.

7 Up contains high fructose corn syrup, which creates a less viscous reaction with gelatin than aspartame. This means that while you will get some foaming from adding Mentos to 7 Up, the reaction is not as dramatic as with Diet Coke and Mentos.

In addition, the amount of carbon dioxide in 7 Up is higher than in Diet Coke, which means that the foam created by the reaction will be more volatile and less stable. This means that the foam will quickly dissipating rather than erupting from the bottle.
