There are many myths around "Coca-Cola" and evenscary stories that constantly stirs interest in this drink. Experiments with Coca-Cola overwhelm the Internet, then creating new myths, then refuting them. Many have already heard about the experiences with Mentos, however, the majority of those who want to repeat them at home did not succeed. We will try to explain the main reason for these failures from the point of view of physics. But the experiences in which "Coca-Cola" and milk are combined, for someone will be a discovery.
"Terrible" truth about "Coca-Cola"
Coca-Cola and milk are two ingredients available.a combination of which may surprise you. Cocktail, which will be the result of experience, is a clear liquid with sediment. How can get a clear liquid from the dark "Coca-Cola" and white opaque milk? Often, such materials on the Internet are anti-propaganda about the use of cola. This is not at all surprising, because during the experiment you can see unaesthetic processes inside the bottle.
Therefore, the titles of such articles are full of titles.like "Think about what you drink", "Poison in a bottle of drink", etc. The worse it sounds, the better, but a reasonable person will always look for more compelling reasons and draw his own conclusions.
We are conducting a milk experiment
Вам не понадобится ничего сверхъестественного и difficult to access, except that you can buy in the nearest supermarket: Coca-Cola and milk. Everyone can conduct the experiment right at home. Ingredients proportions:
- 0.5 l Coca-Cola bottle;
- milk 50 gr.
We take a bottle of "Coca-Cola" and gradually pour intoher milk and then cork the lid. If the lid is not closed, the liquid will tend to come out during the reaction. We leave the bottle for 2-2.5 hours and calmly go about our business or watch the events.
During the experience you will see how in the liquidflakes are formed and slowly fall to the bottom. This waltz of flakes gradually brightens Coca-Cola, making it all the more transparent. At the end of the appointed time, we find that the liquid in the bottle became completely transparent, and at the bottom there was an unappetizing coffee-colored curd. This cottage cheese, by the way, is quite edible, but it is unlikely that someone will want to eat it.
We draw conclusions - to drink or not to drink?
So how to treat this clear liquidwith flakes on the bottom that give Coca-Cola and milk? In some articles, you will read the warnings from using Coca-Cola. Videos with a reaction taking place in a bottle of your favorite drink will surely convince you that you are drinking some kind of chemical. Memories from the lessons of chemistry will also add negativity, because absolutely inedible flakes fell out of the sediment there.
In fact, everything is very simple - componentsMilk react with the acid, which is in the "Coca-Cola", and precipitate. It is not a secret that there is orthophosphoric acid in the composition of the aromatic drink, which causes coagulation. Similarly, the formation of cottage cheese and the separation of whey, if the acidified milk is heated. Nobody stops drinking milk for this reason, as this is a completely normal process.
"Mentos" and "Coca-Cola" - a myth or fiction?
Наверняка все слышали о взрывной реакции refreshing Mentos candies in a Coca-Cola bottle. There are also more impressive facts about what happens when you drink a bottle of Coca-Cola and pick it up with Mint Mentos.
So, many have undertaken to conduct such an experiment anddid not see anything. There is a suspicion that these stories are nothing more than a myth. The reason is that any experience must be carried out under certain conditions, accuracy in the choice of ingredients is also important. If you do everything correctly in terms of chemistry, then a flowing bank with "Coke" is provided to you.
Correcting mistakes with Mentos and Coca-Cola
Откуда мы зачастую берем "Кока-Колу" в supermarket? Of course, from the fridge is the first mistake that makes the experience useless. The fact is that the reaction requires a warm "Cola", in a cold environment all processes slow down, and the experiment does not give the desired result.
The best conditions and ingredients:
- Low-calorie Coca-Cola light (clogged) room temperature;
- Mint Mentos, preferably without glaze and unpainted.
Under the conditions described, a bottle of "Cola" turnedusing candy in a stormy fountain. Immediately it is necessary to warn that this experience is best done not in the house, unless you are planning a spring-cleaning.
Chemical substantiation of the "explosion" in a bottle of "Coca-Cola"
Famous "Mythbusters" on the channelDiscovery did not avoid this experiment and explained how the Mentos and Coca-Cola tandem works. Experiments have shown that this is not a myth, the fact is that the lollipop creates pockets of heterogeneity, in which the dissolved carbon dioxide is released with great force. The remaining components of the drink, such as aspartame (sweetener), sodium benzonate and caffeine, play a role, as well as gum arabic and gelatin in the "Mentos". All of them are perfectly combined and create a chain reaction, releasing all carbon dioxide at once. This makes the cola bottle a stormy fountain that is used to create spectacular performances.
It must be said that the same "Mythbusters"dispelled rumors about a possible damage (or rupture) of the stomach as a result of using Coca-Cola and Mentos at the same time. At least, the stomach of a pig (similar to a human) as a result of making a cocktail in it, which included "Mentos" and "Coca-Cola", remained unharmed. But to conduct such an experiment on yourself is not recommended.
