Mike's "Drop"

I had never tried this with my Nikon flash.  Did it a couple of years ago with my old Vivitar and had to try all sorts of things.
Anyway.  This is my drip or drop or droplet.  You can tell its mine, because if you look really close, I and the camera are inside the bubble!  You will also notice the standard Millard calcium buildup complete with its iron oxide.
