Coca Cola + Mentos Experiment

This is unbelievable! Put 3-4 Mentos chips in the bottle of Coca Cola & Hurray! You get a big fountain!

I'm scared! What about you?

This is terrifying! Coca Cola's reaction was "This is an amusing experiment and it does not go with the (Diet) coke brand" ! :x No doubt why I hate carbonated drinks!

[​IMG] Coca Cola sucks!

It works even with Pepsi! And maybe, just maybe other carbonated drinks too. We still have to try it out 😀

Did anyone really try it?

I'm curious to know the chemical reaction which takes place. Chemical Engineers, can you enlighten us?

I had seen the pictures in email. Not sure if Pepsi too, produces a similar fountain 😁 !

Keep away from Pepsi & Coke and enjoy health 😁 !

It happens for all carbonated drinks and is not a chemical reaction.

As Steve Spangler, explains, "The Mentos effect has nothing to do with the inside of the Mentos and everything to do with the outside." The candy's shell is pocked with little nooks and crannies the beverage's carbon dioxide molecules are immediately drawn to, and the confection's relatively large surface area provides infinitely more such nooks and crannies (nucleation sites) than, say, an M&M would.

As to what happens when carbonated beverage encounters Mentos, when dropped into a two-liter bottle of Diet Coke, a roll of the sweet works to produce an impressive geyser of brown froth that will shoot about 20 feet into the air (although some of these pressurized fountains have attained even greater height). Diet cola of any manufacture is regarded as the liquid of choice for creating a "Mentos eruption" or "Mentos effect" because the drink's brown color serves to make the reaction much more starkly dramatic in all its explosive glory, and diet versions of sodas don't leave the same sticky residue that their sugared counterparts do, an aspect well worth considering when contemplating spraying a wide area that you may afterwards be called upon to clean. Plus, some folks swear diet sodas make for higher geysers.
No need for chemical engineers for a 9th grade phenominon 😀

And bytheway there is a rumor online about a brazilian boy who gets killed by the combinatin. It is not true. Moreoever Pepsi and Coke are pretty safe if consumed in normal amounts, excess of anything is harmful.

That's better 😉

No need for chemical engineers for a 9th grade phenominon :smile:
I was only trying to motivate Chemical Engineers to come forward and post 😉

We have nada threads related to Chemical Engineering 😕
