A trivia thing I heard was that Guinness was the only beer where the bubbles
would fall instead of rising. I think they said it was due to nitrogen gas
being heavier than air, or CO2. My understanding is that there is no CO2 in
Guinness at all.
I found the following bit of info on their site, which could explain what
Andrei saw. I have never seen the "wedge" either.
"In 1999 GUINNESS® introduced the "rocket widget" so drinkers could enjoy
GUINNESS® Draught anythime, anywhere, straight from a bottle."

PS - The typo in the above paste is from their site. Apparently someone had
a wee bit too much :)

It has to be at least 5 years ago or more now that I saw the wedge in
the can. And after carefully studying it we figured they had a gas
charge that would cause it to rotate, which would simulate the
non-laminar flow out of a tap in turn creating the head. But we never
had the time to test the theory. Now if you poor you self a glass, and
let it sit for a few seconds before consuming it, watch the bubbles
very carefully and you will see some of then going down instead of up.
Now somewhere I do have a proof of why the bubbles go down.
