This image depicts a grilled cheese sandwich pull. Made of medium cheddar cheese and sourdough bread, the proteins with the cheese change state allowing them to act as a flow when heat is applied. Melted cheese is a non-Newtonian fluid meaning that it can behave as a solid or a fluid depending on external conditions, but the viscosity and stress vary throughout the process of the cheese pull. The body force of gravity act against the cheese as it pulls apart.

Hi Monica, I was very impressed with this picture! Honestly, this image makes me hungry, especially when you show it at noon. I like how the cheese looks when it’s pulled apart and the color adjustments you made to highlight the cheese. Also, your explanation is good, I didn’t realize that cheese becomes a non-Newtonian fluid when heated. That’s a brand new knowledge for me.
I think this was a really creative choice of phenomenon. I’m glad you chose a non-newtonian fluid; I never would have thought to use cheese. I think the framing provides good context for this image.
How did you make decisions about coloring in this image? Was the goal to highlight specifically only the cheese?
yes, the intent was so the cheese (aka flow) was starkly captured and the first thing you saw when viewing the image. I also hoped it would make everyone want to make a grilled cheese for dinner :)
