A TikToker is going viral after sharing her life hack for how to pour soda without foam.It came to TikTokers courtesy of a user named Hannah (@hanthehoarder).Hannah’s video features someone who appears to be a restaurant waiter pouring a bottle of Coca-Cola into a glass.But, instead of simply tipping the soda bottle toward the glass, he places it all the way inside.The result is a clean, bubble-free pour.At the end of the clip, there’s hardly any carbonation of foam at the top of Hannah’s glass.Some couldn’t understand how — or why — pouring this way would make a difference.Carbonation in drinks comes from carbon dioxide, which forms into bubbles as it releases into the glass.The faster you pour a drink and the further away your bottle is from a glass, the more you disrupt the soda’s equilibrium.
That, in turn, releases more carbon dioxide.This is why you’ll usually see bartenders pouring soda or beer down the side of the glass — because it keeps the drink from crashing hard into its container
