This video demonstrates how phospholipids in milk interact with a detergent, with the aid of food coloring to visualize. The dish soap is a surfactant and reduces the surface tension of the milk, which causes the fat particles in the milk to create the swirls of color seen in the video.

I really like how you used milk as a white background, it’s awesome you were able to find a fatty liquid that also acted as a cool backdrop to the photo. It makes the colors much more vibrant
There are exceedingly interesting shapes in he bottom right hand side of the image. The contrast and various colors is also quite interesting!
I really like the colors you chose to use for the food dye. They are very bright and distinct so it’s easier to visualize the flow from different areas of the bowl. In the future, I would try and frame the video a little different.
I like your choice of perspective, but agree that if you’re looking to do a version in plan you should run this experiment a few more times and try different bowl shapes, zoom settings, etc.
You may also want to play with the light. You mentioned that the milk is very reflective, so you might have to try a variety of lighting techniques, but I think this would really accentuate the diffusive effect.
I like the diffusion of the vivid colors as they arise from the pure white milk. It’s a great visualization of fluid flow as the individual colors help show each aspect of flow. The colors and white milk also make it super visually appealing.
The fade from black and white to color is fantastic video editing and very nice addition.
I think as is, its framed well, but to your question about framing, in my opinion it would be very nice and crisp to have just show the pure white.
I like that the initial setup was very clean and ordered and then the bloom of color looked very organic, like blood vessels or tissue.
Super interesting visualization of how the reduction in surface tension affects the milk! The image is well focused and I loved the color choices you made with the food dye.
I really like the explanation of the chemistry behind the fluid phenomenon and using the food coloring to really show the chemical reaction and how it affects the fluid movement and flow.
