[hide]*Origin 1


The first Coca-Cola, cola was an alcohol-free imitation by John Pemberton, of the Vin Mariani which was devised by Angelo Mariani . Initially Coca-Cola contained an extract of coca, but under pressure from the authorities in the early 20th century this was omitted. The recipe for Coca-Cola remains to this day one of the best kept secrets in the world. The name cola comes from the kola nut, which nowadays however is rarely used for production.


Famous brands cola are Coca-ColaPepsi-Cola, River Cola and Virgin Cola. Other notable brands are Jolt Cola, where extra much caffeine in it, Inca Kola, an important South American brand that is significantly different from the traditional cola, and Mecca-Cola, any part of whose proceeds will go to aid to Palestinians. Also exist in the Islamic world , with the common purpose alternative Colas boycotting America. This includes, for example, Zam Zam Cola and Parsi ColaOpen Cola is a cola whose recipe is freely available under the GNU General Public License.


Apparently Coca-Cola is also a product that an excellent source for wild tales. This is not at all strange: Coca-Cola has been a particularly successful product since the creation in 1886, and pretty much the national drink and symbol of the United States. It formed an important part of the culture and folklore of the twentieth century. Over the years has therefore a multitude of stories and rumors to this thirst-quencher back formed, some of which are quite persistent. A collective name for the tales around Coca-Cola is Cokelore.


Drinking more than two liters of cola a day can cause chronic low potassium levels and lead to muscle weakness and even paralysis. [2]

Cola Fountain[Edit]Edit

[1][2]Coca-Cola light and Mentos

A well known entertainment is to cause a Coke fountain using Mentos or other sweets that go directly to the bottom sinks. If a bottle of coke is opened, the pressure in the bottle. This changes the chemical equilibrium between the carbon dioxide dissolved in the cola, (CO2), and the liquid. Because less carbon dioxide can be dissolved in a liquid under low pressure, there will be, according to the principle of Le Châtelier, another set and will balance the excess carbon dioxide in the form of small bubbles release. This process can be accelerated with a strong catalyst; for this is often Mentos used. The confectionery itself takes no part in the reaction, but the surface with its microscopic bumps and cracks strongly promotes the nucleation of the carbon dioxide and ultimately the formation of large gas bubbles. This increases also the necessary volume for the gas and the liquid strongly, and because the bottle will not turn off the gas-liquid mixture under high pressure spray from the opening of the bottle. [3similar effects can also be reached with other strongly carbonated beverages such as Champagne and some Belgian beers such as Duvel.
