The mentos and coke thing is a reaction between the carbonation and the rough surface of the mentos. The water would dissolve the surface rather quickly, even in ideal scenarios, and as you melt the ice, you wouldn’t be able to re-expose the surface fast enough for a meaningful reaction. Just all around an impractical plan.
If I remember right from a video back when mentos and Coke was all the rage, it wasn’t just the texture of the mentos but there was also a chemical reaction in the combination of the two is what led to the violent reaction.
" These additives are thought to enhance fountaining by lowering the surface tension of the beverage"
It’s a still a physical effect, not a chemical reaction. The additives allow the physical effect to happen more rapidly because the water has lower surface tension.
So… You’re just being a pedantic ass because I said chemical reaction instead of chemical component (or something to that effect). Really…
My general point still stands. Diet Coke creates more of a reaction with mentos then regular Coke. It is more than just nucleation points on the candy.
It is more than just nucleation points on the candy.
It isn’t more than nucleation points on the candy. I already provided a source. There are many more. Using a liquid that allows nucleation sites to work better doesn’t make it a chemical reaction.
Suppose you have two liquids with different surface tension and each liquid is mixed with marbles. You pour the liquid through a strainer leaving the marbles behind. The fact that each liquid pours at different rates doesn’t make pouring the liquid a chemical reaction. It’s the same liquid before and after pouring. No chemical reaction has occured.

That’s not correct, the surface of a single mentos provides nucleation points in abundance for the physical reaction.
