The ink droplets
Snapshots of the ink droplets containing 50 vol% alcohol (isopropanol) as they spread on a surface coated with 400 μm-thick acrylic paint with different paint concentrations (11%, 20% and 33%), captured over approximately 40 seconds. The images on the rightmost column show the zoomed-in views of the droplet edges. Higher paint concentration leads to increasingly refined and fractal-like droplet edges.
