Neva asked the Naked Scientists:
   
Why do we thump a can of soda water (or Coke) if it has been dropped or shaken up?

What do you think?

To shake the bubbles off the sides of the can. That way they've already surfaced and popped before you open the can, if they're still on the side of the can when you release the pressure they'll make a foam which will go everywhere.
