‘Hydrocarbon vs Ink – Implosion’
The flow visualization is driven by the Marangoni effect – the movement of fluid from lower to higher surface tensions. I was mesmerized by the quickly moving ink; the way that it at first was driven swiftly away from itself, only to gather back together in an outer ring, and later in the video as a sort of nucleus in the middle. I was reminded of galaxies but also retinal patterns as I watched this video. Truly stunning. And I just think the purple is pretty.
This visualization comes from Chemical Bouillon – I couldn’t find their names, but it’s three french guys who have an entire YouTube channel dedicated to “studying the graphic aspect of chemical reactions.”
