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."

    "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

      The problem here is that 'bubble' means two different things. A 'soap bubble' usually means a spherical layer of liquid, hanging in air, with air inside it. They have two liquid-gas surfaces. Another kind of bubble is simply a blob of gas inside a liquid; it has only one surface.

      The article refers to the first kind of bubble. That way their definition of antibubble works perfectly, reversing the liquid and the gas in a (soap) bubble.

    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.

    I didn't find a video but, this site clearly explains antibubbles and includes several good pictures of them.

    Note that it's VERY easy to blow antibubbles. The main trick is to set up a clean liquid surface with a bit of detergent in the water.
