Have you noticed that if you pour pepsi into a glass , it remains fizzy. But if a plastic cup, it goes flat?

Question

And if you pour pepsi into those cheap plastic "SOLO" cups, forget about it... it goes TOTALLY flat INSTANTLY.

WHY DOES IT DO THIS? Does plastic eat the carbon bubbles somehow?

Maybe this can be used to solve global warming !!!

Its called nucleation, cheep cups have non-smooth sides, so more nucleation sites for carbon bubbles to form.  glass is generally very smooth, less nucleation sites, less release.
