Hologram-like structures materializing

Close-up (~500 X)  of  the rim of a sauté pan I'd left  in the sink. The  branched filaments formed IN the  sitting water, and when I took pictures, I  noticed that the same structures that  always seem to  co-exist seemed to be  *under* the surface of the metal. I initially assumed it was a reflection, but then,   some  seemed to break  through.  I rubbed a chopstick along the surface and some seemed to be physical structures. Others seemed to be light. Blue hue could be due to blue dish soap.

The garbage had leaked into the garbage container. In person, I couldn't see the haze that is visible in the following images/video.
