Abstract
Antibubbles refer to drops of liquid that are surrounded by a thin gas shell with the whole object immersed within a liquid phase. Although first observed more than 70 years ago, only recently have details of the formation and disappearance of antibubbles been considered. Here we provide an experimental study of the optimal conditions necessary for the formation of antibubbles. In addition, we characterize the dynamics of the collapse of the liquid column, formed from the initial impact of a drop with a liquid bath, which eventually leads to the antibubble.
