Is eating mentos with coke harmful, why?

Answer 1

Mentos is a sugar based candy.
Coke is a carbonated soft drink.
So why the hell woulf they interact?

you can definitely eat and drink at the same time but make sure YOU DONOT CHOKE buddy.

Answer 2

The reason why mentos causes a carbonated drink to expand lies in the carbonated drink itself. In a typical carbonated drink, the CO2 infused into the drink gradually forms bubbles (if you observe, they form on the surface of the can or bottle).

When you throw in a mentos, what happens is something called "nucleation". Nucleation can be pictured as something like this: let's assume that, like in animated cartoons, that a snowball can fall down a slope and as it does so, it gets bigger and bigger. In order for this to happen though, you need a ball big enough so that it'll roll down in the first place. A tiny snowball as big as a nickel probably won't roll down as good as a soccerball-sized snowball. So only soccerball-sized snowballs will lead to the formation of the huge snowball.

In a regular carbonated drink, a lot of CO2 gas is coming out but it's a very slow process. If you throw in a mentos, the process of nucleation takes place - CO2 particles actually use the mentos candy as a place where they can mass together extremely quickly due to the simple fact that the microscopic surface of a mentos candy is extremely rough (and thus has a very high surface area).

Similar to how snow can easily attach to a soccerball-sized snowball rolling down a slope to quickly generate a behemoth-sized snowball, mentos acts the same way when you throw it into a bottle of soda. You're just increasing the rate of release of CO2 (which builds up so fast it actually shoots out the carbonated drink with it).

Answer 3

The only thing that will happen is that the force of the mentos and coke will "force" out of your mouth. You will be a human fountain basically. I have seen a few people keep it in their mouth without letting it spew out.

Other than that, nothing harmful will happen to your body. Just don't choke on the mentos. And make sure that you don't take too big of a drink that you can't handle it.

Answer 4

Carbonated water is the one that causes the geyser.
Think of it this way, acid reacts with carbonates to give CO2 the same it does when mentos is added to coke, but you are still walking around fine after spending most of your life drinking coke.

Your stomach contains acid. (HCl)
