2-5 seconds, be ready to clean up a BIG mess
Surprisingly, it takes less than a second if you have a brand new bottle of Coke.
Mentos do dissolve but they realease Co2 which creates pressure in excess with the Co2 in diet coke (the thing that makes the bubbly feeling in your mouth is Co2) Which is why the stuff overflows and explodes.

see how long u can open your eyes for then record your results or classic diet coke and mentos or dry ice in a swimming pool
If you put mentos in your mouth for a long enough time without chewing, yuou would soon find that the texture of the mentos changes to a slightly rough surface. The soft layer before that will dissolve in water, like in your mouth. When the mentos is put into the coke, the soft layer is dissolved off. The rough sorface of the mentos releases the carbon dioxide dissolved inside the coke (H2CO3), but the mentos is small, and can only hold a little ammount of the carbon dioxide. But once the carbon dioxide is released, this reaction cannot be reversed, all the excess carbon dioxide rushes out. This set-up will work best on diet coke because it contains no sugar to act as impurities.
When you drop Mentos into Diet Coke, the bottle will become a geyser, shooting soda up to 20 feet high. This happens because the Mentos' surface catches the small carbon dioxide bubbles and connects them into much larger ones. When the bubbles break off the candy's surface, they burst and cause the soda to shoot out of the bottle.
A Soda FountainMentos contains a chemical known as arabic gum (this is the ingredient that makes the mint "chewy"). This ingredient causes the surface tension of the water molecules to break even more easily, releasing carbon dioxide gas. However, this is not the primary reason for the release of carbon dioxide gas . If you look at a Mentos with a powerful microscope, you will see that it has a very rough surface, that looks somewhat like pumice. This bumpy surface attracts the carbon dioxide in the diet coke to the point where a bubble forms, at which point it's released and rises to the top of the coke. Multiply this by a couple million times around the entire Mentos, and you have a fountain!See Related Links for a demonstration & practical joke idea
it will rot a way to see this process happen quicker u can drop an ice cube in a cup of coke, then a couple secs later, pour out the coke and look at the little creaders in the ice, that's like a cavity for ice
Sure, coke can kill dogs, or people. I am not sure if you refer to cocaine or to Coca Cola, but either can be fatal in sufficiently large doses. In moderate doses, Coca Cola is perfectly safe. Still, I would advise you to give your dog water, not Coca Cola.
no becuse coke has bin around for long
add more mentos!
depends how hard you shake it and how long the coke was opened
No, it is the long OO (long U) sound, as in boot and moot.
