This example of a Saffman-Taylor Instability was made by injecting water into turquoise-colored corn syrup within a Hele-Shaw cell. You can see sugar streaks, dispersing into the water at the interface of each viscous finger, that seem to travel back towards the center of the ‘gloop flower’. Watch as the small bubbles are hugged by the petals as they grow accompanied by large bubbles with reflections of sparse indigo LED lights from Target.
Special thanks to my team members Cameron, Maddie, and Nicole for moral, and literal, support. They did not aid in the making of this photo per se, but each was present at some point in the experimental process that led to this result.
