Metallic textures and cavitations

It seems that there are endless surprises to be had in the Fluids Lab, and yesterday was no exception. I was intrigued at the regular textures which can be generated with a very slow-moving flow – The ink in water can take on the appearance of shiny metal. I also produced lines of bubbles, which, when they popped, left amazing patterns behind on the surface of the ink as evidence of their existence. Perhaps bubbles are not so ephemeral, after all.
