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.

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 also repeatedly talks about a reaction. No reaction here - or at least, the coke might react to the mentos, but it doesn't react WITH the mentos - there isn't a reaction in the chemistry sense. — Preceding unsigned comment added by (talk) 16:21, 21 October 2015 (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)


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.


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)
Off topic chat

Diet Coke works better , I would speculate, because Diet Coke is demonstrably less dense than regular Coke due to having no sugar content. There is a famous demonstration which shows that a can of Diet Coke will float in water, while a can of regular Coke sinks. Certainly, given equal force generated by the pressure of the expanding CO2, the less-dense (and therefore less massive) fluid would travel further into the atmosphere, producing a more spectacular show.

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.

"Huge explosion"[edit]

Removed the words "huge explosion." Huge compared to what? TNT? Hermanoere (talk) 13:09, 19 July 2016 (UTC)
