Uncorking a cold bottle of champagne releases carbon dioxide gas in a series of shock waves, many of which are faster than the speed of sound.

Champagne uncorking may seem simple, but high-speed images have previously shown that high-pressured, cold carbon dioxide gas escapes in a more complicated series of steps than expected. “Champagne should be considered a ‘mini’ laboratory for the physics of fluids,” says Robert Georges at the University of Rennes 1 in France.
