Coca-Cola Fountain is completed by the physical reaction between Coca-Cola and mentos mints.

Introduction to Coca-Cola Fountain:

1. In recent years, a game called "Boiling Coke" has become popular internationally. The attraction of the game is that it can produce 10 to 50 cm "boiling water column"! Players from all over the world conduct experiments in their own backyards or bathtubs. Some schools in the United States even take this kind of game as an extracurricular activity, demonstrate it to the whole school students on the playground, and then post the spectacular scene of coke eruption online to share with friends all over the world.

2. Some mints were thrown into Coca-Cola. A few seconds later, a huge column of coke spewed out of the coke bottle, leaving only half a bottle of coke in the bottle after spraying. This game was originally a "brave man" during June 2006 1 65438+1October1Singles Day.

3. Steven Waltz and Fritz Gollob took this idea to the extreme. They put four or five mentos mints in two liters of coke, and shared 523 mentos and 10 1 bottle of coke. Under the action of candy, coke erupted in large quantities, forming a water column as high as two meters, which had a wonderful effect and simply copied a Las Vegas.

In 2005, Coca-Cola Fountain became a hot phenomenon on the Internet. When mentos sugar is put into 2 liters of diet coke, the chemical reaction between them will form a fountain. A high school physics teacher uploaded this reaction process to the website, which brought amazing hits. Many people even grafted the Bai Le Palace Music Fountain in Las Vegas to the Coke Fountain. Sales of Coca-Cola and Mentos also rose sharply.

5. Experimental steps: Open a new bottle of cola (the effect varies with its quantity), quickly put in four mentos (10 is optional, the better the effect), and quickly empty. Friendly reminder: the pressure is high when the gas erupts, so it is recommended to choose an open place to finish it. Accustomed to drinking a lot of coke and swallowing a lot of mantuo immediately, it is estimated that the situation may be different. Some people have done human experiments online, and their painful expressions can explain the problem.

Phenomenon reason:

1. Lan Hongqiao, Ph.D. in Chemistry, Xiamen University, explained the principle of this phenomenon to reporters. The gel and resin released by "Mantos" mints after entering water destroy the surface tension of cola liquid. There are many tiny pores in mints, which is an ideal place to form carbon dioxide bubbles. "Mentos" mints contain gum Arabic, which makes the surface tension of water molecules easier to be broken and makes cola release more carbon dioxide at an alarming rate, so it can be sprayed so high.

2. Dr. Lan also said that mints contain many pectin substances, and the pore structure of these substances physically reacts with carbonic acid, which will accelerate the release of carbon dioxide. If you eat these two things at the same time, a lot of carbon dioxide will be released in the stomach, which will increase the burden on the stomach and cause stomach pain, which is not good for your health.

It turns out that there is a lot of carbon dioxide in coke, and high pressure is used in the production process. When the bottle cap is opened, the pressure drops and carbon dioxide is released from the coke.

However, this process is usually slow. Careful observation shows that most bubbles are generated from the bottle wall. This is because the generation of gas is usually attached to some surfaces or some particles, which is called nucleation.

There are many small holes on the rough surface of Mentos. These porous structures make Datura become a good "core" for gas production, and a large amount of carbon dioxide can be attached to the sugar surface.

6. The density of manta rays is higher than that of water. After adding, it will sink to the bottom immediately, and the bottom will generate gas quickly, which will help to spray the liquid at the bottom.
