The Science Behind Champagne Bubbles' Straight Line Rise

Researchers have discovered why champagne bubbles rise in a straight line, unlike those of many other drinks. The unusual trait is down to particular ingredients in champagne that not only give it flavour but attach to the bubbles, changing the motion of the fluid immediately behind them as they rise and hence allowing the bubbles to form a chain. The straight lines of tiny bubbles within champagne are down to flavour molecules, such as fatty acids, within the drink that have surfactant properties.
