This and yesterday's post are part of an experiment to photograph "fluid dynamics."

Using a small spice bottle I put water in and dropped a little bit of dye in, then tried to photograph the result. With hot water the ink dispersed too quickly to really capture. Cold water was slower, almost too slow.

The hardest part is lighting. Started off using the light box with four bulbs, but that still wasn't enough to stop the "action." Finally settled on the remote controlled flash positioned almost behind the jar.

Yesterday's photo was the clear water after being filled, with bubbles still swirling around the container. Today's is after the ink has been dispersing for a while.

In both cases the photo has been rotated counter clockwise ninety degrees.

Cool! Nice shots.
I'll never forget my experiments in making a series of bottles that had fluids of two different densities; one fluid clear and the other, heavier one, dyed blue, to simulate ocean waves in slo-mo.
My first one was tightly filled in a glass bottle. I was playing with it while sitting on my bed, and the heat from my hands caused the liquid to expand enough that it broke the bottle in my hands! The incredibly-noxious liquid spilled all over the bed, and stank for days, while I slept in another room! My 2nd generation used plastic bottles that could expand enough without breaking...
