A regular soap bubble is a thin film of liquid surrounding a sphere of air and floating in an air medium.

Now think of the exact inverse: a thin film of air surrounding a sphere of liquid and floating in a liquid medium. That is called an antibubble. You can make them in a beaker of soap bubble solution.

An antibubble, with its modest bouyancy, floats slowly upward to the surface just as a soap bubble floats delicately downward.

This YouTube video has other permutations: zero gravity bubbles, bubbles-within-droplets, and a "bubble war" filmed in slow motion and explained by a NASA scientist.

This is the second posting of bubbles you've posted. Do you have a interest in bubbles? Very cool stuff. It makes me think of cells and on a larger scale universes and the idea of the multi-verse theory. Maybe gravity waves travel across the universe in a similar way. I love astronomy and was wondering if it is synonymous with being interested in art. Are you also interested in or maybe an avid astronomy buff? You obviously have a fair understanding of the scientific principals that go into making a painting ring true to life.

Your scientific posts are as enjoyable as the art ones.
