What makes carbonated beverages foam out of control when poured in specific ways?

220 views

We all know the experience of buying a nice bottle of Coke, pouring it into a cup and that MF just foams up like crazy and out of the cup.

Other times, when we pour it slowly with an angle, NO FOAM! crazy stuff.

Why is that? What makes it foam or not foam?

In addition, you can poke the foam and not only does it stop foaming more, but the foam also dissipates much faster! HOW?! WHY?!

Man if this happened during the middle ages someone would be burned for witchcraft.

Everything from a soda to a beer have ideal pouring angles/speeds.

In the Middle Ages, they knew how fast to pour Meade or Ale.
