The molecules that give champagne its flavour wrap around the bubbles in the drink, letting them rise in a straight column without disturbing each others' paths
and champagne. They then poured the liquids into a thin rectangular tank with a needle at its bottom, pumped in bursts of air through the needle and recorded how they rose.The researchers combined these observations with a mathematical model that describes how certain properties of liquids determine the amount of swirling that happens near a bubble. The researchers found two characteristics driving swirling: the size of the bubbles and the concentration of molecules called surfactants.
Understanding the interplay between surfactants and bubbles is complicated because bubbles’ motion can change surfactants’ concentration by spreading them around in the liquid, saysat the University of Liege in Belgium. Insights like those provided by the new study could also have implications for non-carbonated drinks like whiskey, where trade experts already estimate the alcohol content by shaking bottles and seeing how they bubble, he says.
at the University of Reims Champagne-Ardenne in France says that understanding the behaviour of groups of bubbles is also important for industrial processes like froth flotation, where bubbling is used to separate different particles mixed into water.
