Here are some inksplosions I have taken recently that show ink being stretched; in some cases, quite a long way. Many inks seem quite comfortable with that; they are very elastic. As we see from these four images, different inks behave in different ways when undergoing the same outward movement.
‘Oval window, Bubble eye’
‘Extremo-chromaphile’
‘Aqua vortex, yellow window’
‘Windows within windows’
