For Christmas we got a Keurig coffee maker. Today after refilling the water reservoir I noticed numerous bubbles on the side of the plexiglas container that were lighted by the blue LED light of the coffeemaker. I got out my extension tubes and used all three to capture this sci-fi looking image that reminded me of robotic orbs.
Two informational points:
1) These bubbles are about the size of a head of a pin.
2) Like anything man made, they can be used for good or bad.
Of course best when viewed large on a black background.
