Making Antibubbles in Beer from Belgium
An anonymous reader writes "About.com reports on "Antibubbles in beer from Belgium". Scientists in Belgium have studied the movement of antibubbles (the exact opposite of regular bubbles) in Flemish beer. They found that the beer was very similar, but not the same as, dishwater.
You can also learn how to make antibubbles in your kitchen from soapy water."
Of course, some beers are more like dishwater than others.

They linked to an 'About.com' article, and therefore must have been drinking too much beer this afternoon.
Thank you.
"...dishwater"
For anyone who's seen a slow motion video of a bubble bursting, that sounds like it looks very similar. The whole forming and bursting of antibubbles is interesting, because from the articles it sounds like they're very similar to normal bubbles. That seems like it would imply some kind of air-counterpart to surface tension.
Did she fart in the tub and make antibubbles?
At least looking at the picture for makign antibubbles with dishwater, these merely look like bicelles. Basically, the detergents line up so that their hydrophobic tails interact and their hydrophilic head groups form a barrier on each side, just like a lipid bilayer in a cell membrane. Air is in the tail layer, and water inside and outside.
sort of makes you wonder what the relationship is between science and beer with the amount of research that has gone into beer.
I mean.. how many articles have been on slashdot about "scientists discover why bubbles in beer go up/down/sideways in space/a vacuum/on the moon" etc etc.. Seems like hundreds over the years..
I am not complaining.. I mean, I sit there and look into my beer and wonder about the bubbles sometimes.. just wondering who is paying for this research?

I read that article, and was thinking: "Huh?" A lot of the time. I feel better after reading everyone's comments here... it doesn't look like I was alone.
Hmm, I've never heard anyone claim that Flemish beer is like dishwater... If dishwater was anything like Flemish beer, I'd drink dishwater all day! Of course, Westvleteren 12 is the greatest beer in the world.

O'Douls can produce antibubbles? And if so would it then be an Antibeer Antibubble? Or is it still just gross.
Boredom's not a burden anyone should bear.
So presumably they had to split the beer atom right?

If they met, it looks like they'd probably end up forming a larger bubble or antibubble depending on which of the two was more stable.
Picture: Large glob of air suspended in water touches hollow sphere of air (anti-bubble). I'd guess that the antibubble would collapse, perhaps partially doing a 'jellyfish effect' but probably largely the air would reform a bubble with the original bubble. Perhaps it'd go the other way and the air from the bubble would flow in and enlarge the anti-bubble's surface area. It'd probably depend also on the mixture, whether it was more bubble or anti-bubble friendly.
Can anyone find anything to the effect of which is more stable? Which one would make it in a fight, bubbles or antibubbles?
an antiburp sound like?
"If you think you have things under control, you're not going fast enough." --Mario Andretti
An antibubble is a droplet of fluid surrounded by an gasseous membrane, as opposed to a fluid membrane around air. Of course, creating a gasseous membrane is a much more difficult proposition than creating a fluid membrane, which is why this is such an interesting discovery. (well, that and because it relates science and beer...)
When discussing the death of the antibubble, Dr. Dorbolo states:
Wouldn't an antibubble just decompose to form a regular bubble of gas within the liquid? Or is he saying that the gas is re-dissolved into the beer?I think the 'exact opposite' of bubbles would actually be raindrops.
William of Ockham had no beard. The most likely explanation is that it was chewed off by squirrels every morning.
all of this talk of drunken beer revelry studying bubbles in the guise of science is just irresponsible
you see, it's almost new years eve, so we should be talking about drunken champagne revelry studying bubbles in the guise of science

Just as a bubble is a spherical liquid membrane separating two gases (One gas being inside the spherical membrane), another definition for anti-bubble is a hollow, spherical extent of gas separting two liquids (One liquid being inside the spherical extent of gas).

A bubble-antibubble drive could be used to probe the outer rim of Uranus.
I was a proto-geek at a young age... when supposed to be washing dishes, I spent a lot of time making antibubbles in the suds. And regular bubbles. And, well, pretty much anything but washing dishes. Or maybe I was just a well-developed procrastinator. If only I'd been old enough to make antibubbles in beer! Time for some make-up experimentation... And if this is only now being studied, then I was waaaay ahead of my time.
I prefer to be called Evil Scientist.
"Scientists in Belgium have studied the movement of antibubbles (the exact opposite of regular bubbles)"
I always get a bit annoyed when I see this type of thing. Calling them 'antibubbles' makes them sound exciting, saying they are 'the exact opposite of bubbles' makes them sound intriguing.
The exact opposite of a bubble would be an airborn droplet.
These are 'hollow bubbles' if anything
Send er down capin'.
Here is a link to an article . I looks like they produce a cell membrane with air in the middle.
This membrane is stable because the hydrophobic chains of the surfactant molecules are slightly electronegative.
"anti-bubbles in my Guiness?... Brilliant!!!"
Hot Damn! It's the Soggy Bottom Boys!
Here all this time I thought the reverse of a bubble would be a droplet.

An antibubble is not a bubble that floats downwards. It's a bubble whose membrane is made of air instead of fluid.
I didn't find a video but, this site clearly explains antibubbles and includes several good pictures of them.

I was disappointed not to see any pictures of these "jellyfish forms."
Indeed, the first thing I thought of when I read that passage was D'Arcy Thompson's On Growth and Form.
I just got out my copy to check and, specifically, I was thinking of Chapter V, pp. 388-398, "On Falling Drops," which is an extended essay on similarities in form between (on the one hand) various kinds of splashes, liquid jets, drops of ink falling in water, etc. and (on the other hand) jellyfish and other medusoids.

So the Sirius Cybernetic Corporation has moved to Belgium? That would explain why they have this liquid there that is almost, but not quite, entirely unlike dishwater. Or real (german) beer.

So, like..bubbles in the beer are filled with..beer?
I for one do not approve of their research methods, they did not provide proof that no beer was hurt during their experiment.
If they tampered with beer's magical formula for the sake of "antibubbles", then I consider them unethical.
--"The perfect example of the man of action is the suicide." - William Carlos Williams
Dammit people, get your nomenclature right. Both air and water are fluids! Air is a gas (well several, but...), and water is a liquid (at room temperature, when it's called "water"...), but both of these are fluids. So, the whole "bubble of fluid inside of air, inside of fluid" doesn't really make sense.
Why, when you can have a beer?

Yes and no. True, the opposite of an UNDERWATER bubble is an airborne droplet.
However, the opposite of a soap bubble in air drifting on the breeze is an antibubble drifting around underwater.
The part about beer is interesting because it's analogous to blowing soap bubbles on an extremely humid day: the bubbles last longer, or possibly last forever if the air is slightly supersaturated.
An antibubble in beer would collect more and more carbon dioxide into its thin gas layer. If it didn't touch the fluid surface from below, there'd be no reason for it to burst.
Although first observed and studied almost a century ago, no one until now has been able to determine how they form.
Yeah, right. Even little kids have been making antibubbles since that article came out in 1974. If you've tried making them, it's totally obvious how they form. Perhaps what's not totally obvious is why a thin layer of air is stable underwater. But if detergents can stablize an air/water interface in a normal bubble, then this explains both a water film in the air, and an air film underwater.
Antibub trivia: antibubbles have "rainbow" colors, but the rainbows in the opposite place from a soap bubble: they appear at the bottom of the sphere. And of course the rainbows in both bubbles and antibubbles are not rainbows, instead they're antirainbows: dark spectral slots in white light. They're bands of "subtractive colors;" cyan, magenta, yellow.

I've known about these for years. Seen 'em in dishwater. Seen 'em on soda. Never seen 'em on beer, though. Glad to see somebody else noticed 'em and decided to study 'em.

This sounds like the kind of bar trick that you could use to win a free round in a bet. Saying to your friend that you could produce an antibubble would sound interesting. So my question is how would you do it? The article mentions using a squeeze bottle, but that's too complicated for the pub. Just squirt beer out of your mouth? I haven't tried it using either method, so I have no idea how hard it is.

You can laugh at anti-bubbles, but some very fine wine is made by the Summerhill Estate Winery in British Columbia. Their secret, they swear, is that it is aged under a pyramid so that "all the atoms spin in the same direction".

As a guy that generally likes beer, I just want to say that it's hard to get head when your glass is full of antibubbles.

The exact opposite of a bubble is called a drop.
I just read this article, and I'm glad I saw it. While at work today (liquor store), I was shaking up a bottle of creme de cacao and noticing that some of the bubbles were hanging around for some time, and a few actually were large enough to see easily, and they sank to the bottom. I was kinda weirded out by this when I say it. So reading this article really put some sense to it. Though I don't know why it happened with this particular substance.
why only kitchen, you can get them in bathroom too. looking at the Figure1 in the pdf posted arxiv.org , it looked quite familiar to what i have often observed in bathroom, while trying to fill an empty bucket with water, tap being around 0.7 meter atop the bucket base, regulated to yield a continuous little flow. next time i visit there, i need to confirm this. If it is then it indicates antibubbles can be formed without any detergents stuff. or might it be that municipal corporation is supply water with detergents so that citizens can save on soaps etc.. :-)
Another way could be to inject liquid inside trapped air in liquid, using some fine syringe. with expertise multiple small liquid droplets can be created inside the trapped air volume by having a syringe filled with alternate columns of liquid and gas, like --
pistonend-[liquid-air-liquid-air-liquid]-needleend
may be this technique helps getting stabler anti-bubbles easily and earlier and might be for longer lifetime? since during antibubble formation the disturbation/movement in the system is much smaller compared to pouring technique.
I was wondering if Dr. dorbole also considered observing fusion of two/more antibubbles? it should look like reverse process of cell-division.
two small cells fusing together to form a bigger cell [considering inner trapped volume of liquid akin to cell nucleus]
No need to go down to your local pub, you can get this fresh taste by getting a can of Guinness from you local super market. It is charged with nitrogen when you open the can. The process for the 'nitrogen cakes' in the can is described in U.S. patent no. 4,832,968 .
Interesting stuff - thanks
Is this the story with the most off topic comments?
Who cares about anti-matter here, this isn't anti matter it's just called an anti bubble. The anti matter jokes are just annoying. I liked the beer comments more than anti matter comments, but they aere still far too many.
as of this comment I've only seen three other comment sactually on topic.
Now the part that gets me on topic:
How does this liquid supported by gas in a liquid work? What forces are strong enough to keep the relatively dense liquid from comprerssing or displacing the gas below it and making contact with the other liquid?
I read some about surface tension and hydro-repulive forces, but even still would the gas on the bottom be a apparently thinner than on the top?
I'm not able to understand this can someone help me?
