Subject: How does a spoon help keep sparkling wine fresh after being opened ?

If you hang a small spoon into an open, partially emptied bottle of 
sparking wine, with the handle of the spoon into the neck of the bottle, 
the wine will retain it's "fizz" for significantly longer than if the 
bottle was left unstoppered. How can this be ? The bottle top is almost as 
open to the surrounding atmosphere, given the edge-wise surface area of 
the spoon, yet the contents remain almost as potable as if it had been 
recently unstoppered. Wine Waiters always seem to advise usinga silver 
spoon, but I can't see how this might make a difference. Perhaps they're 
just being superior ....
