  A theory of the collapse of a punctured antibubble is developed. The motion
of the rim of air formed at the edge of the collapsing air film cannot be
described by a potential flow and is characterized by high Reynolds numbers.
The rim velocity is not constant but gradually decreases with time and is
determined by the balance between the surface tension and hydrodynamic drag
forces. A collapse equation is derived and solved. The agreement between the
theory and existing experiments is shown.
