Hi Jim,

As I note in a separate post, Peter Davenport emailed me to say
that in fact the hole was reported to be almost exactly the same
size as the object.

While the mechanism may be elusive, altering the droplet size
distribution is certainly less prohibitive energetically.
Indeed, at constant mass, a small number of large droplets is a
lower energy configuration than many small droplets, due to the
reduction in surface area. The puzzling aspect is how these
droplets could coalesce on such a short time scale.

The localization of the effect does not rule out this mode in
principle, since rain-out from clouds can also be limited in
extent, although presumably not to such a well-defined
