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.
Don't anthropomorphize computers, they don't like it.
But does the beer explode?

How about making dishwater that tastes like beer?

Antimatter Beer? That's a hell of a bite.
And why did you staple the trout to the RAM?
Do the antibubbles make you antidrunk?? or just antisocial?

In sink, add beer to dishwater. Stir.

"...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.
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?
anime+manga together at last.. in real time.
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?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).
I make my face look like this and concerned words come out.
The exact opposite of a bubble within a liquid, yes. But a bubble is actually a gas, trapped within a thin membrane of liquid, in gas. So the exact opposite is like they said, a liquid, trapped within a thin membrane of gas, in liquid.
"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
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.
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 believe if the Bubble and Anti-Bubbles were to mix, they would annihialte each other, producing a massive headache!

You could produce some sort of beer warp field from the reaction. I am sure commander Scott would approve...just pour some Guiness into the Warp Core! Saves us from having to pay for all those expensive di-lithium crystals!

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.
The coolest bubbles I've seen in my kitchen are bubbles in hot cocoa that contain an island of dry powder.

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.
