Hey guys...I tried the experiment and i obviously didnt do any research to find it has to be a bottle. What i did is put the coke in a cup and dropped some mentos in and only a little fizz happened. now ive run out of mentos lol so i should have researched first..

"diet" works, not BECAUSE of the aspartame, but because of the lack of sugar. disolved sugar in water is ionic and slows this type of reaction. several other factors do contribute to the reaction, some of which were named previously: nucleation sites, gum arabic and its water-tension breaking properties, both of which help the violent release of all of the CO2. Also, the acidity of the diet soda helps to immediately disolve the mentos, causing more nucleations sites and even more reaction. This experiment is like a physical version of a nuclear bomb, but instead of massive amounts of heat, light, gamma rays and subsequent radiation, the only products are all of the CO2 in the soda; flat, no-longer-carbonated diet coke and all of the energy exerted by the escaping gas. AS previously on this chain, DO NOT SCREW THE CAP BACK ON!!!! This is WAY TOO VIOLENT a reaction to assume that the thin plastic of a 2 liter or 20 oz. bottle could handle the pressure. THE BOTTLE WILL BLOW UP AND YOU MAY GET HURT OR HURT OTHERS.

Hmm. Well, I dropped three mentos into a glass of pepsi. It didn't explode, but it sure did fizz a lot. I'm drinking Pepsi/swallowing mentos right now to see if I get bloated. Hmmm I do feel a little pressure at the back of my throat... I'll have to do this again (not in my body but in bottles) with different kinds of soda. I'll let you know if I ever get around to doing it

did you no you can die from this if you put it in your mouth da DUH !!!!!!!!!!!!!!

i like bannanas over mentos any day 😛 but im doing this experiment for school so i was searching up information on this experiment.

wow it is so amazing i did it at my school with my teachers and it went so high......... yea it was alot of funn it got on my teacher lol =D

First, there definately is some chemical in Mentos that participates in the eruption. To prove that's it's not all about the nucleation sites, take a Mentos and dissolve it in water. This way there won't be any physical structures, just the chemicals. Then pour this "Mentos water" into a soda. Tada! It still foams up like crazy.

Likewise, other substances that reduce the surface tension of water also cause the soda to release it's pent-up carbon dioxide. For example, dissolve a little dishsoap into some water, then toss that into a soda bottle. You'll get a really good fizz-over.

Certainly nucleation sites contribute to fizzing, but that's only part of the story.

umm ya i saw the mythbusters episode also on this and what that guy said is true about it it was a really kool episode also i get to do this as a presentation at my church and so ya

If you try it with mint mentos and diet coke it willl probably work when you eat em.

:) :lol: okay you guyws no wat you are all saying different things wat is really true does it explode in your stomache or wat because noone can get this straight

me and alexa might be doing this for science fair07-08 and we will need mentos and diet sodas and just what and see waht happens!!!!-what do you think the effects is going to be when you mix up mentos and diet soda?!

:-) i did this in science it was masive :zip:

no thing happens when you drink soda and then eat mentos.. all you feel is a little bit of gas and thats all. then you have to burp but thats about it

whats in mentos ?????

i bvet you that if you drink some diet coke and then eat mentos but not chew them then swallow them your stomach would probably explode. but if you chew them then your stomach wont explode.
Hehe thats just a thought though
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! YEAH YEAH YEAH YEAH YEAH YEAH YEAH

umm... it does work with regular coke, mountain dew, etc. It just works best with diet coke. And only some kinds of mentos work. Certain flavors of mentos have a waxy coating that covers up the "nucleation sites". Hope this helps 😊

hi it was sweet!!!!!!!!

:lol: i always thot that was a myth till my science teacher did this.

woah hey.

whatssup home slices

My daughter did the mentos/cola reaction for her science fair...it was interesting. It seems that caffeine free cola has the largest reaction that we got. We used Cola, diet, caffeine free, and just to see we used Dr.pepper too. We also used another mint to see what would happen and well mentos did win the other mint did have a reaction in the caffeine free, all the other colas did not foam over. Interesting find I think.

ha ha you guys say "pop"
i just call it soda.. thats cute!! =)

It is mostly caused by nucluation...i spelled it wrong...thats when Co2 gets caught in the microscopic dents in the mento which creates bubbles. there are other things too such as the gum arabic. It can also be done with seltzer water....with less of an affect.

omg u guys are all gay

this xperiment is pointless

this was an old science project of mine but i guess i didnt do it right because it didnt explode like in the picture so i dont beleive that it went that high.

I am going to do an experament, putting mentose with diet coke, regular coke, and carbanated water, on my calculations, the diet coke should react the most, but do you think that the other sodas might react better if at a cooler temperature? if you have any hypothasis, just e-mail me... .(JavaScript must be enabled to view this email address)

just so you know, i'm not an adult...i'm 15, so yeah...nothing to smart

wow that really cool im doing a project for this this could help!!!!!!!!!!!!!!!!

lol, thats great, did you find out some information??

if i drink pepsi & then swallow mentos will i blow up ?
