Why does Mentos make the coke react?

Answer 1

Mentos fizz because of the nucleation sites on the surface of the Mentos. These are basically microscopic holes and when it comes into contact with the coke all of the dissolved carbon dioxide condenses and form bubbles that wear away layers of the mentos where more nucleation sites are accessible by the carbon dioxide. This is why the reaction is not repeatable with the same coke or a flat coke.

Answer 2

I don't actually know.
It must be the formula of the two products, that make a chemical reaction inside the liquid.

People like you make me puke. Why post an answer that starts "I don't actually know." If you don't actually know, then shut up and stay away. The reason that Mentos make coke fizz is to do with the surface structure. The surface is covered with tiny pits that release CO2 gas from the drink at a rapid pace, resulting in the froth.

Answer 3

the pore (indents) in the mentos reacts with the carbon gas (cant thing of name but gives the coke fizz). this reaction makes a huge amount of carbon gas which rushes and makes the "eruption"

Answer 4

The surface of the metos dissolves as the carbon dioxide (CO2) breakes it down, the eating up of the coating of the mentos forms a fizz that is visible to us.

Answer 5

mentos react with coke because there is more than 2 solutons in the coke that makes it fiz

mentos is made of powder and coke reacts with powder so that is why it reacts xx
