First, here's a drop right before the splash. I estimate its diameter
at about 4mm.

When the drop hits the surface, it creates an outgoing shock wave,
which crests and becomes "a crown".

After the crown falls, all is left is a crater. The secondary milk
drop seen is perhaps the tail of the original one, which splits off
and falls more slowly because its relative surface area is bigger.

Here the crater had refilled, and the impact of the secondary drop
created a "crater within a crater":

When the crater refills, it closes up with such a force that a column
of milk shoots up and then falls down:

A column of milk shoots out following the impact of a milk
drop (beginning).
