Clarified at last: The physics of popping champagne
When you uncork a bottle of champagne, complex supersonic phenomena occur. Scientists at TU Wien have now been able to calculate exactly what happens for the first time.

Atmospheric pressure is sometimes defined as the force per unit area exerted against a surface by the weight of air above that surface at any given point in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location. Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation. A column of air one square inch in cross-section, measured from sea level to the top of the atmosphere, would weigh approximately 65.5 newtons (14.7 lbf). The weight of a 1 m2 (11 sq ft) column of air would be about 101 kN (10.3 tf).
