An antibubble is a droplet of liquid surrounded by a thin film of gas, 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. 

If antibubbles can be stabilized they can be used to form a long lasting froth — antifoam. Possible uses for antifoam are as a lubricant or using the thin passageways permeating antifoam as a filter for air or other gasses.

Antibubbles themselves could be used for chemical processes such as removing pollutants from a smokestack. Replacing the air in antibubble shells with another liquid could be used for a drug delivery system by creating a shell of liquid-polymer around a drug. Hardening the polymer with ultraviolet light would create a drug filled capsule.
