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.

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

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.

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#

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 wouldn’t work, the water would change the texture of the mentos before the soda hits it.

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.

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!

Smh soda needs to get on board and stop being a little bitch with its soda-tongue pickiness. Try something new, soda.

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.

No, for several reasons.

Ice would expose mentos way too slowly. Mentos being in water and freezing would have already removed the texture that makes it work to begin with. By the time the ice melted enough a lot of the carbonation would have already escaped the soda. One mentor isn’t enough to cause much reaction. The soda would be cold from the ice and that slows the release of the cO2…

No. As the soda would lose most of the carbonation pouring it into the glass

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
