Vortex rings generated by dry ice sublimating in water within a plastic cup, discharged through a quarter-inch hole illuminated by an LED. Some rings are fully developed while others are captured in the process of formation.

Statement of meaning: I really liked how you captured the path of the vortex rings, and how the center of the image is the most in focus.
Its really cool that you captured multiple vortex rings. It shows the progression of the vortex rings in time and space which informs vortex formation and propagation.
The multiple vortexes really add a lot of motion to the image, really highlights the changes that the vortexes experience over time.
I like that multiple rings at different stages of formation are shown and that the depth of field makes the differences in depth apparent.
