Alternate candies[edit]

Mentos are hard to come by in the UK, and I would imagine other countries outside of north America. Has anyone tried this with a substitute candy such as might be readily available in other countries such as the UK? If so how did it compare to the Mentos? —The preceding unsigned comment was added by (talk) 00:20, 9 February 2007 (UTC).

I tried to use skittles and starburst but it turned out really bad. Plus you can order mentos online @ their website.-March 2007

Says mythbusters: table salt also works. 15:04, 16 September 2007 (UTC)

Bottle Caps (candy) work too. but I'd assume any chalky candy will work. Weaselboy246 (talk) 08:23, 6 August 2008 (UTC)

Many other products can be used, but there is NO REASON to mention either of these by name. That is advertising, and doesn't belong on wikipedia. --MacRusgail (talk) 16:34, 28 October 2008 (UTC)

But somehow saying the reaction is exclusively between Mentos and Coke isn't advertising??? (talk) 19:32, 5 September 2010 (UTC)

It's not hard to find Mentos in NZ or Malaysia Nil Einne (talk) 15:26, 23 November 2010 (UTC)

Mentos originally come from the Netherlands and have been widely available in Europe long before they made it to the US - maybe this once more shows that the UK is indeed, despite all reason, not part of Europe? *scnr* -- (talk) 12:59, 30 May 2012 (UTC)

There are Mentos outside the US, if you take the Eurostar, you will find them in almost every French shops. — Preceding unsigned comment added by (talk) 16:37, 7 September 2013 (UTC)

Scientific Data?[edit]

I was trying to find out what reaction occurs between the mentos and the diet soda. This article claims that CO2 is released. Really? How do we know this? This article is a big load of crap. We don't need "theories" we need test results. I got 5 bucks says Carbon and Oxygen are split from the CO2 molecule in the soda causing the rapid expansion. Why do I think this? Because if you do this reaction and add heat there's a combustion reaction. CO2 doesn't explode, oxygen does. Mythbusters isn't the best source of information to be citing. This article is useless to anyone trying to learn about what it is that actually happens when you put mentos into diet soda. They might as well just link to the youtube videos. Mojination (talk) 19:36, 4 October 2011 (UTC)

Well, a few ideas here. First, I would have to imagine to Intergovernmental Panel on Climate Change would be very interested in this if you were right... All of the sources cited (not just Mythbusters) point to nucleation as a primary cause. None of them point to a chemical reaction (which, in your theory, seems to be occurring without any thermal changes...). Additionally, having seen this done, I don't know where all of that carbon would be going, as the soda after the eruption tastes like flat soda (no hint of pure carbon) and carbon gas certainly is not involved at near STP conditions. We have nothing showing this supposed combustion reaction. - SummerPhD (talk) 20:41, 4 October 2011 (UTC)

The article quote Mythbusters results when fruit-flavored Mentos with a smooth waxy coating were tested in carbonated drink there was hardly a reaction, whereas mint-flavored Mentos (with no such coating) added to carbonated drink formed an energetic eruption. But the Science of Mentos-Diet Coke explosions explained article from New Scientist says Another factor is that the coatings of Mentos contain gum arabic, a surfactant that further reduces surface tension in the liquid. Rough-surfaced mints without the surfactant did not create such large fountains. These two quotes seems to be in direct contradiction. Are US Mentos the same as EU Mentos? I bougt some EU Fruit Mentos today to try this for myself. The ingredients include glazing agents (carnauba wax, beeswax). Can anyone comment on US Mentos? (talk) 22:33, 15 December 2013 (UTC)


Requested move[edit]

Soda and candy eruption → ? – Diet Coke and Mentos eruption was the original name as this is what seems most commonly used experiment. It was moved to the current Soda and candy eruption title without discussion due to non-comercialism. I am thinking either back to its original title or Coke and confectionery eruption as a more neutral title. Simply south...... creating lakes for 5 years 20:54, 5 October 2011 (UTC)

I just moved it back. It was done as a followup to MacRusgail's campaign above claiming that the product mentions are advertising, which received no support and ample disagreement. It was originally moved contrary to consensus some 8 months after that discussion. If MacRusgail disagrees, no problem for him to try to get consensus for a move to something else. In the unlikely event that that happens I'll be happy to do that move as well.
The article does need more coverage of other ways to produce this reaction, though, since it is true that it is not limited to those two products. Perhaps someone could do the useful work of researching sources for that and adding more content? Jamesday (talk) 05:07, 6 October 2011 (UTC)

More Mentos[edit]

Does more Mentos produce a bigger geyser? Because of the mentos' porous surface, it creates CO2 in bubbles, so, in turn, "spits" it out. So, does more Mentos create more CO2 bubbles because of all the Mentos' porous surfaces combined, more or less?

Thank you.


I came to this article hoping for a history section. How long has this been known about? When was the first reference? It seems like everyone became aware of it about 6 or 7 years ago, but before then it was unheard of. — Preceding unsigned comment added by (talk) 00:39, 20 February 2013 (UTC)


The diet coke has an ingredient in them called glucose which makes the explosion the biggest. — Preceding unsigned comment added by (talk) 19:40, 19 December 2013 (UTC)

Glucose is a sugar. Interesting theory, but no. - SummerPhD (talk) 00:57, 20 December 2013 (UTC)

In popular culture[edit]

Per WP:IPC, I have removed the trivial primary-sourced list of occurrences in popular culture. - SummerPhD (talk) 00:30, 7 October 2014 (UTC)

File:Diet Coke Mentos.jpg to appear as POTD[edit]

Hello! This is a note to let the editors of this article know that File:Diet Coke Mentos.jpg will be appearing as picture of the day on January 11, 2015. You can view and edit the POTD blurb at Template:POTD/2015-01-11. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 14:11, 22 December 2014 (UTC)

Diet Coke and Mentos eruption

A Diet Coke and Mentos eruption is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the liquid to spray out of its container. The mints cause nucleation that releases dissolved carbon dioxide so fast it pushes the liquid up and out of the bottle, in what has been described as an eruption or geyser. Though this was demonstrated on television as early as 1999, the reaction went viral in 2005, after Steve Spangler posted a video to YouTube.
