The white froth is just called the "head" of the beer
Bubbles in My Beer was created in 1947-12.
The process of adding bubbles to beer is called carbonation. This is typically done by injecting carbon dioxide (CO2) into the beer during the brewing process.
Fermentation
As a result of brewing beer and wine with a sugar and yeast, the yeast consumes the sugar and produces carbon dioxide (which makes the carbonation/fizzy bubbles) and alcohol.
There are soap bubbles, carbon dioxide bubbles in carbonated drinks, air bubbles trapped in ice, and bubbles of gas released during fermentation processes like in beer or bread-making.
its a mug with bubbles on top. like beer.
"beer foam" or "head" is hydrophobic proteins in beer that make tiny bubbles when beer is poured. Breweries put lots of effort into making sure there beer has an appropriate amount of head for the style.
Nitro beer and CO2 have different impacts on the taste and texture of beer. Nitro beer has smaller bubbles and a creamier texture, giving it a smoother mouthfeel. This can enhance the flavors of the beer and make it feel more velvety. On the other hand, CO2 creates larger bubbles and a more carbonated feel, which can make the beer taste crisper and more effervescent.
Carbon Dioxide, a by product of the fermentation process is the standard cause of the bubbles. In many large scale breweries, CO2 is used in the bottle process. And there are some beers that are nitrogen bottled.

When you open a beer, carbon dioxide gas that was dissolved in the liquid is released, causing bubbles to form and create foam.
First basic beer physics. Beer contains carbon dioxide in solution at equilibrium (it doesn't want to come out of soluion). As the pressure in the beer is removed (you pop the tab or remove the cap) it seeks a new equilibrium concentration and some gas comes out of solution and the liquid foams up. Beer contains surfactants (chemical) that trap the gas in bubbles (foam). As the beer warms more and more gas comes out until the beer goes flat. What else makes the gas come out? If the beer is shaken, dropped, spilled or jostled the energy shakes some of the gas out of solution and the beer foams up. If you put salt in the beer it changes that chemical composition of the beer and provides small particles for the bubbles to form around and the beer foams up.
