Hydrogen bonds keep soda fizzy for longest

Strong and lasting hydrogen bonds could be the reason an opened bottle of soda stays fizzy for longer than a bottle of cola or champagne, a team of researchers has found. The size and stability of bubbles in fizzy drinks influences their taste, which is why many scientists have studied how gases escape from different drinks. But this is the first study that looks at what happens on a molecular level when a drink goes flat over time.
