A while back my cousin told me that the little ball that’s inside causes it to not foam over but I don’t quite understand how. I don’t quite understand the logic or even connect the dots.
In: Chemistry
The ball inside some beers is a NO2 filled ball that breaks open when the pressure changes in the can, ie you open it. The beer is lightly carbonated or in some cases not carbonated at all and the nitrogen creates the foam. Thus shaking the can does little to nothing in terms of creating more foam.
