diet coke+mentos

[Doc. Josh]

I was triying to figure out why diet coke and mentos mints have a chemical reaction, and if you eat a mentos then drink diet coke will it have the same reaction? And what is it that its only diet and mentos and not other pops? Thanks for my amature question.

Can't really explain anything that's not on there, if you have trouble understanding something feel free to ask.

 

Also other carbonated beverages do this, it just seems that diet coke works a bit better. I do not know exactly why this is, but I can make a couple of conjectures.

Non-diet beverages contain a lot of sugar, this could reduce the amount of CO2 that can be dissolved in them (diet coke is fizzier, if you will)

Something about the artificial sweetner/lack of sugar makes the froth that forms in the diet coke more stable (think suds/froth in soapy water vs pure water. A bottle of detergent in some rapids would make a real mess)

this would mean that the CO2 being released would be more likely to force it out of the bottle rather than escaping around the sides.
