Erin asked the Naked Scientists:
   
I hope that the Naked Scientists can burst this bubble... 

I have heard that carbon dioxide bubbles cling to the sides of a soda can, and that the release of pressure is what causes soda to fizz up when you pop the top... the carbon dioxide rushing to the lower pressure air outside.

So, does tapping the lid of a soda can before you open it dislodge the bubbles and prevent it from foaming over? Or is that simply a bunch of hot air?

What do you think?

Hmm - I'll see why this is a duplicated question...
