Antibubble

Submerged antibubbles of air surrounded by soapy water
Cluster of antibubbles on the surface of soapy water

An antibubble is a droplet of liquid surrounded by a thin film of gas,[1] as opposed to a gas bubble, which is a sphere of gas surrounded by a liquid. Antibubbles are formed when liquid drops or flows turbulently into the same or another liquid. They can either skim across the surface of a liquid such as water, in which case they are also called water globules, or they can be completely submerged into the liquid to which they are directed.
