This image shows a multitude of Saffman-Taylor instabilities of dyed water (less viscous fluid) through honey (more viscous fluid). Originally injected through a hole in the top plate of a Hele-Shaw cell into the center of the honey, the water formed Saffman-Taylor instabilities emanating outward radially. However, after the water reached the end boundary of the honey it burst out and quickly surrounded the honey. When the injection syringe was removed, the change in pressure pulled water back into the honey, creating Saffman-Taylor instabilities directed radially inward, an effect I thought was unique compared to a typical Hele-Shaw cell experiment.

Hey there Bradley!
You really rocked this! Great job capturing instability! I love the finger like tendrils that come of. The image is really easy on the eyes. Great work!
Your group nailed this set up. Great job capturing the form of a Saffman-Taylor instability, this image is super interesting to look at.
This photo is striking. The contrasting colors are awesome and I think that your editing did a great job of enhancing this photo.
I like the way the purple and yellow combine and create an orange hue, as well as having some background which helps to make the shapes stand out.
Hello Bradley,
Your use of contrasting colors is super beautiful. I really like how this image turned out, along with the rest of your teammate’s images. I think this idea is super cool!
The purple is really cool. Your editing enhanced the effect really well. I really appreciate that you chose to use the same setup as your teammates but took this photo from a different perspective. The clear curvature of that boundary is really remarkable too!
The color gradient and the brightness of the colors are quite spectacular. Very cool image you have, nice job!
