Beer Bubbles Really Do Sink
Galvatron writes "A group of researchers at Stanford have shown that, despite being lighter than the beer itself, bubbles can actually slide down the sides of glasses. So, if you see it happen, it's not just that you've had too much to drink. For a description of methodology and an explanation of why it works, see the article."
This story is just asking for a frosty piss joke to be made!
odd, I've seen many a drunk sliding down the side of a glass...those pesky bubbles!
Nothing - well thats something.
Wasn't there a story on /. a few years ago about someone researching why the bubbles in Guinness were apparently sinking - with the conclusion that they are driven down by streams closer to the centre of the glass?
Love over Gold.
when you're high, can dogs really fly or is it just the weed?
So do bubbles going around the glass mean I'm half-way there?
I've finally got a fan! Now what do I feed him?
I have seen bubbles moving down at the edges of my Guinness. This latest "discovery" seems to be common sense to me, and is exactly how I have explained the phenomenem to other drinkers down the pub.
Shame I wasn't paid to do my "research", and that no-one would have listened to me because I didn't have a 750-frame-per-second video camera.
Now, this story would have been really interesting if it had a link to the videos of it happening 'cause it really is a sight to behold!
Of course it depends which way your head is up, or down - sometimes they go sideways in both directions.
Not being a beer drinker I am not surprised, the bubbles are probably trying to drown themselves rather than taste that foul brew...
..women at the bar can really like you! If one of them is turned on by your presence it's not just that you've had too much to drink!
"While the pair's finding will be invaluable to barroom betters across the globe it also has legitimate scientific value in the area of fluidized beds, the mixing of solid particles with liquids and gases, which has industrial and engineering applications."
It's amazing what people do come up with to get an excuse for drinking beer.
I'm not saying that this is not valuable information, however if only they had googled before hand they would have noticed that this WAS ALREADY KNOWN ABOUT IN 1998! see this story at http://www.sciencenet.org.uk/database/phys/liquids /p00053d.html
What's more this has been done 4 years ago more here
Saying Apple is better than MS is like saying Botulism is better than rabies.
"So Andy got hold of a camera that takes 750 frames a second and recorded some rather gorgeous video clips of what was happening."
So quit hoggin' it and let us have some of that sweet sweet goodness.
For any newbies: Apparantly your intelligence is increased by drinking alcohol, since it kills off your poor quality brain cells leaving more room for your high-powered brain cells.
So kids, if you want to pass your exams, sneak into Daddy's Spirits cabinet and have a swig before breakfast.
Now I have a new chat up line to use: hey babe, ever stop and think about bubbles moving down? Hello? You didn't finish your drink!
I had a class with this professor earlier this year. This really explains his teaching style... he must have done his beer "research" each day right before he lectured...
There's a video about it here: video/mov,4MB
Mentioned in news article from
Ouch, how smart is it to have an article about beer on a Sunday! ;)

Damn - I wish I had never seen this article. I've always used that observation as a definite measure when to stop drinking beer. Now I won't know when to stop. I'm sure this article has been sponsored by the breweries.
ought to have better things to be doing than looking at bubbles in beer glasses dammit.
quickly turn the glass upside down over your mouth
Without further independent research that confirms this data, I won't believe it... As my contribution to mankind, I will be donating my time to this endeavor this afternoon, right after work... anyone else care to volunteer?

What these researchers have described is anomaly in gas-liquid mixing. In the field of chemical engineering, the mixing and flow properities of gas-liquid reactions are ongoing research subjects for the last several decades, particularly in fluidized bed reactors. Fluidized bed reactors are very important in the production of a wide variety of chemicals. While the test subject may have been fun for them to explore, it may hold clues into how gases and liquids mix in a reactor and this back-mixing may other researchers develop more accurate theories and simulations. These simulations then lead to better processes.
Well, there's spam egg sausage and spam, that's not got much spam in it.
