It seems like every time I pour a cup of diet Pepsi, it's flat well before I even get half done with it. Regular soda stays nice and bubbly until I'm done....hell, I've even left a can of Coke open on my nightstand and drank it in the morning and it was fine, a bit warm but fine and yummy.
is it normal diet sodas go flat ultra fast? So annoying.
Diet Soda never used to go flat .. It's only within the past 10 years or so it's lost it's fizz - quickly!
It's probably the artificial sweeteners. Drink organic sodas like Zevia or Oogave.
Soda goes flat for me after 3 or 4 sips.. haha. I HATE diet soda it has the worst after taste....and taste for that matter.
Things are only fizzy because of a process called nucleation. The carbon dioxide is attracted to an impurity which then becomes a "seed" for a bubble (or, technically condensation nuclei).
And now I'm stuck because sugars are simple isomers and in no way large enough to act as condensation nuclei, so the absence of sugar doesn't imply the absence of fizz.
I don't know, OP. You've stumped me! And now I am going to obsess about this until I ask one of the Professors at work.
I think Pepsi and diet Pepsi both go flat sooner than Coke and diet coke. Switch to diet coke or coke zero.
