Does Coke Plus Mentos Die What happens to Sementos after a Coke enema

Coke plus Mentos candy can be fatal. Recently, a post titled "Mentos Candy and Coca-Cola Eating Together Will Be Fatal" has been widely circulated in major **, in addition to the text description, there is also a "Coke Fountain" demonstrated by netizens**. Among these**, a dozen Mentos candies are placed in a freshly opened Coke bottle, and a coke "fountain" of up to half a meter is sprayed in a matter of seconds; And the experiment with Wangzai's small steamed buns also had the same effect.

At the same time, rumors that "two people died in Brazil" have caused even more panic.

Regarding this problem, Fan Zhihong, an associate professor at the College of Food Science and Technology of China Agricultural University, said that he had heard about it. But she said it's nothing new for cola to form fountains, because the carbon dioxide in coke is added at high pressure, and if shaken or heated before opening the bottle, it is entirely possible to spew out a large amount of liquid. Champagne, beer, etc., also contain a lot of bubbles, and it is possible to have the same effect, but people will not appear strange when they drink it, and the "Fountain Coke" hurts people a little sensationally.

Yu Kang, deputy director of the Beijing **** Nutrition Department, also said that the human internal environment is not the same as the test environment and cannot be generalized. In this regard, Wang Lei, manager of the public affairs and communications department of Coca-Cola of Coca-Cola Company, said that because the appearance of Mentos mints is loose and easy to absorb water, when it encounters carbon dioxide in carbonated drinks such as Coca-Cola, it will undergo a soaking effect and produce a large amount of foam. "But when you eat sugar, the surface of the sugar is immediately destroyed by chewing and saliva, so there is no foam when it comes to carbon dioxide. ”

Coke is a carbonated drink, and Mentos is mints, the effect of these two things colliding together is not ordinary, a large number of bubbles will be produced, Coke is like a fountain gushing out, if these two things are drunk into the stomach at the same time, it is estimated that the river will be turned upside down, an Indian brother plans to try it like this.

Wangzai's small steamed buns are useless! Deceitful! I tried! (Upstairs).

Mentos erupts when you put it in a Coke, so what happens if you put a Mentos in a Coke that has been in for five days?

Mentos. The principle of the reaction between mints and cola to release a large amount of gas is:

1. The structure of the Mentos candy itself.

The reason why there is a lot of carbon dioxide in cola.

This is because of the high pressure used in the production process, which is reduced at the moment the cap is opened, and the carbon dioxide is released from the cola. However, this process is usually slow, and a closer look reveals that most of the bubbles are generated from the walls of the bottle, because gas production usually needs to adhere to a certain surface or certain particles, a phenomenon called nucleation.

If you zoom in a hundred times, you can see that there are many small pores on the rough surface of these sugars, and these porous structures make Mentos a good gas-producing "nucleus", and a large amount of carbon dioxide can be attached to the surface of the sugar. Moreover, the density of Mentos is greater than that of water, and it immediately sinks to the bottom when it is added, and the gas is quickly generated at the bottom to help eject the liquid from the top.

2. Surfactant in Mentos candy.

Two substances are often used in the production of Mentos sugar, one is gelatin and the other is gum arabic.

All are natural surfactants. Water molecules.

There is a strong hydrogen bonding effect, and the bubbles produced must be pushed open to break through the tightly connected water molecules to be released, so as to establish an environment conducive to the formation of bubbles.

Mentos reacts with Coke, which releases carbon dioxide, and there will be **.

The addition of the Mentos brother state promotes the rapid release of dissolved carbon dioxide in Coke, producing an eruption or even a small ** effect, Mentos contains a chemical called gum arabic, which encounters Coke containing carbonate components, so that the surface tension of water molecules is more easily broken, prompting the rapid release of dissolved carbon dioxide in Cola.

Two substances are often used in the production of Mentos sugar, one is gelatin and the other is gum arabic, both of which are natural surfactants. There is a strong hydrogen bonding between water molecules, and the bubbles produced must be pushed open to break through the tightly connected water molecules to be released, so as to establish an environment conducive to the formation of bubbles.

The reason why Mentos promotes the rapid release of carbon dioxide from cola

1. The structure of the candy itself: cola contains carbon dioxide integrated under high pressure, after opening the lid, the air pressure becomes low, and the carbon dioxide will form bubbles and release the ears, but the effect is not very obvious; If you magnify Mentos a hundred times, you can see that there are many small pores on the rough surface of these sugars, and these porous structures make Mentos a good gas-producing core, a large amount of carbon dioxide can be attached to the surface of the sugar to produce, and the density of Mentos is greater than that of water.

2. Surfactants in candy: There are two substances often used in the production process of Mentos, one is gelatin and the other is gum arabic, both of which are natural surfactants. Both gelatin and gum arabic contain glycoproteins, which reduce the surface tension, i.e. the bracket against the newly formed bubbles is greatly weakened.

Adding Mentos to Coke is like adding a lot of bubbles, the sugar looks smooth on the surface, but under the microscope it looks like the surface of the moon, cratered, densely covered with protrusions and small craters, and a large number of bubbles will be produced on the surface of Mentos.

Two ordinary mint-flavored Mentos candies: the moment the sugar is inserted, the bubbles immediately appear, and gradually increase, the speed increases, about 3s, the "fountain" appears, the height is about 20cm, and lasts for about 10s, after that, the "fountain" gradually disappears, and the liquid in the bottle is finally only about half left. But for some time afterward, bubbles continued to form, and a closer look revealed that they were mainly coming from the surface of the Mentos.
