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.
"The eruption is caused by a physical reaction, rather than any chemical reaction. " https://en.m.wikipedia.org/wiki/Soda_geyser
" 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.
Mythbusters:
Your point was that a chemical reaction, presumably gas creating, occurs besides the already established effect. The paper you linked just mentions that some dissolved compounds can lower the surface tension which can promote bubble forming. This is not a chemical reaction and the distinction is important.
Would you be able to find the video? I had never heard of this, and can’t imagine what “chemical reaction” could occur beyond the carbon dioxide simply coming out of solution.
Probably the sugar. Sugar decarbonates coke (and other sodas) pretty quickly. Add to that a container under pressure with only a small hole and you get an explosive reaction.

That’s still not a “chemical reaction” though. It’s just a result of the rough texture of the sugar, same as the mentos.
Soda is full of sugar, so I don’t think that’s it.
Yeah, but it works. When she was little, my sister did it all the time because she loved soda, but only without the carbon.

Not trying to argue, but I remember doing this as a kid, and solidly remember that diet sodas worked WAY better than full sugar varieties
I can try, but that was probably 15ish years ago. So much has come and gone on the net since then.
I think it was mythbusters? It was something in diet drinks increases the effect over a regular soft drink.
For now, this is the best I think I can offer https://pubs.acs.org/doi/10.1021/acs.jchemed.6b00862#
That wouldn’t work, the water would change the texture of the mentos before the soda hits it.
Ok ok, plan B then:
We freeze the end of a rope in ice that they unknowingly throw in their drink. The other end of the rope holds a bucket of water above the chair they sit in. Once the ice melts, the rope will slip out and the water will come down on them. They will never know what happened!
Put two ends of a cable under that person’s chair, once water comes down it will close the circuit, which will in turn cause a piano to fall on their head!
Plan C. We just throw the coke in their face!! PRANK!
Then yell “it’s just a prank bro!” And run off
Even if it didn’t change the texture, it wouldn’t be a sudden explosion, but a slow release. The ice would melt off, slowly exposing the surface of the Mentos. To get the explosion they want you have to throw the Mentos in quickly.
What if you had piece of ice with an air cavity where the Mentos is placed, then sealed in? I think that might work, bit it’s certainly tricky to set up.
Once the air cavity is breached, you have a few droplets of liquid touching the candy, effusing minor volumes of carbonation and then slowly diffusing with the rest of the soda.
Smh soda needs to get on board and stop being a little bitch with its soda-tongue pickiness. Try something new, soda.
Who hurt you?
I did
They’ll spill in my apartment, don’t they? Or do you regularly gift away ice cubes?
It’s actually a self-prank
The real prankster is OP
People drink soda other places than indoors.
Hwat is this so called “other place” that’s not indoors?
Would that even work? As the ice melts, only a small part of the mentos would be exposed, with a gradually increasing surface area. But I’d expected it only works because of the whole surface being suddenly exposed.
I’m more wondering how you freeze them all so without dissolving.
Quickly.
Perhaps dip them first in a simple syrup to buy a little time, then start with very chilled water, add the mentos, then freeze quickly? I have doubts about the whole affair though.
Chill the mentos in advance, too. Things are usually less reactive when cold.
Clever!
No. As the soda would lose most of the carbonation pouring it into the glass
Poor it along the side of the glass, you animal.
Yes, however the (oh god no! I’m being that guy!!) pouring it into the glass even carefully down the side loses the carbonation that “makes” the mentos and coke work. You really can only do it from in the bottle
Really? Are you sure it’s not just the shape of the bottle vs a glass? I’m not super familiar with the reaction, myself. Never heard about it not working in a glass.
You need to drop the mentos in pretty quickly after opening the soda, because even the loss of pressure reduces the reaction fast
Huh, interesting.
Well you just trick them into microwaving their soda!
Hah! Joke’s on you. I drink that shit fast and swallow the ice cubes whole.
Oh no, I’m burping so hard, you guise…
*Burps a fireball*
Mmm, spicy!
am I the only one who drinks things too fast for this to work
Why the fuck is there a disk in my ice cube?
I have friends that would ask the same question in the same confused tone, and I love it
So how do you freeze them?
Would they even still have that wonderful property after freezing?

well YOU’RE C/FUNNY!
sorry I just wanted in on the weird conversation
Step one: have fiends
