The image shows dyed oil poured into water glass. The dye is oil based and only colors the oil. When poured, the oil initially sinks to the bottom of the glass and then rises to the top creating a lava lamp like effect.

The size distribution of the oil drops is fascinating: it makes for a great composition and it also could be interesting to look at scientifically.
How did you decide on how long to wait for the oil to rise before taking the photo?
The depth of field that you managed to capture is very nice, I appreciate the artistry of the larger blobs in the background being visible but just slightly out of focus.
An excellent capture of forces interacting near equilibrium
What was your process for focusing the camera?
This image demonstrates buoyant forces really well.
