Since going knickless beige, I have resorted to drinking soda water. I’ve noticed that plain soda water fizzes more when poured than either plain sugary lemonade or plain sugar-free lemonade or indeed other soft drinks, all at the same temperature. What is the mechanism by which this may occur?

gas coming out of suspension at points of nucleation

But the beverages with stuff in would have more nucleation points, so they should be fizzier. Unless you’re talking about effervescence in general, which I already understand.

Perhaps the lack of sugar or sugar substitutes ?

Does the fizziness vary with temperature?

Yes, but at the same temp soda water is different to the others.

is that a perfectly spherical glass in a vacuum?

It is usually more heavily carbonated.

all the bubbles seem random

is there a way to make the bubbles into patterns?

I might look into buying a soda making machine

Etch patterns on the inner surface of the vessel.

A story I came across recently (maybe here?)
Bubble control

Ah, a fluid mechanics question. For example, sometimes nucleation if heterogenous (triggered by particles and surface flaws) and sometimes it’s homogenous (occurs without triggers). Rate of gas diffusion is another factor. But let’s turn to the web:

“An excessive amount of carbon dioxide is the main factor responsible for bubble growth in carbonated beverages, whether produced naturally via fermentation or added artificially. But other factors also play a role in bubble formation, including the degree of diffusion of carbon dioxide within the liquid. In order to test the extent to which diffusion influences bubble formation, Liger-Belair measured carbon dioxide concentrations inside equal quantities of five different beverages: champagne, sparkling wine, beer, soda and carbonated water. To his surprise, he found that even though champagne and its close relative, sparkling wine, had about the same diffusion measurement for carbon dioxide, their bubble sizes were significantly different.

“Liger-Belair’s conclusion: Contrary to expectations, the diffusion of the carbon dioxide was not the main factor determining bubble size in champagne, although it did play a major role in the formation of bubbles in the other beverages he examined. Based on his study, Liger-Belair says that other chemical components that are dispersed throughout champagne, including dissolved salts, carbohydrates, and minerals, play a bigger role than previously believed.”
