How to make a fountain Coke and Mentos

Today we will make a real fountain.To do this we need the following ingredients: Mentos - chewing pills are popular all over the world.

Brand "Mentos" owned by "Perfetti Van Melle".The first pellets were produced in the Netherlands in the early 1950s.Jelly beans are covered with hard outside shell of taste, under which is a component of chewing.Classic package containing 14 chocolates.

Cola - one of the most popular among young people (after beer of course) carbonated beverages.Contains caffeine, phosphoric acid, sugar, and other useless igridienty.The name is derived from the kola nuts, originally used by beverage manufacturers as a source of caffeine.You can choose any other silnogazirovanny drink, but it is better to choose Coke because it's a classic.

If you get jelly beans in a Coke or any other soft drinks there is an active release of a gas dissolved in the beverage, resulting in a sharp foaming.It is noteworthy that the acid-base reaction does not take part in this process.

reason foaming surface roughness of pills that are carbon dioxide release centers.The process is also enhanced in the beverage additives such as sweetener aspartame (sweetener).Sweetener reduces the surface tension of the liquid, which in turn facilitates the separation of gas.Bottle size also plays a role, ierising bubbles of gas are secondary focal points.

Other ingredients that play a role in the evolution of gas: sodium benzoate (preservative), and caffeine in Coca-Cola;gum arabic and gelatin in chewing dragees.The strongest effect occurs with Diet Coke without the glaze and jelly beans, because they are more rough and porous.

Further study showed that the reaction was caused by the physical properties of chocolates and is not related to the chemical composition.

To date, the record for the height of the fountain of Coke is 9 meters, was put Jamie Heinemann and Adam Savage - the leading program "MythBusters."The previous record - about 5.5 meters - was the discoverer of this phenomenon, Steve Spengler.
