The researchers at the University of Gothingen found that a typical explosive sound when opened with the opening lid causes the causation of the condensation, standing on a cervix. This is stated in the scientific article published in the journal "Physics Liquids".
To understand this phenomenon, scientists have used a high speed camera, which shoots up to 16,800 shots per second, as well as sensitive microphones that record up to 100,000 Herz Frequency Voices. During the experiments, they recorded the condensate inside the beer bottle (the product of the frozen material from the gas condition of the frozen material) varies up and down. It is he that creates a wave that forms the famous cotton, or, as it is called the English-speaking world, Plop.
When the cover suddenly opens, carbon dioxide and air air rapidly expanded, cooling up to approximately -50 ° C. This instant temperature slows the spread of sound, but at the same time, the level of sound pressure inside the bottle reaches a comparable level of a turbine level near the plane.
The bottle movement itself also has an additional contribution to "beer music." The exhausted carbon dioxide increases the level of liquid, and a sharp blow on the cover of the cover provokes more balloons, sometimes even forcing the drink to erupt the drink.
