The slow motion really illustrates how different the nail polish travels down each liquid. It was interesting to see how the nail polish interacted as it crossed the interface of each liquid.
Your video showed how the viscosity of the surrounding fluid affects the shape of a drop. The nail polish drop seemed to deform more readily in the top fluid layer compared to the bottom fluid layer. Maybe the speed of the falling drop also plays a role. Great job!
I really like how in this video we get to see the drop fall through 3 different fluids and how it interacts with the two different interfaces. Seeing the differences back to back is very interesting.
I think the choice for slow-motion did a really good job displaying the behavior of these fluids, more so than a still image would have.
I really liked the visual difference in the properties of the two fluids, and how bits of the nail polish that were corroded by the acetone fell off in the oil. Also I think for a video like this, with a slender container, maybe crop the frame to fit the container and have the frame pan to track the nail polish.
I really enjoyed this video. I think it was a great idea. I would like to learn more about the interactions between acetone and nail polish. I am also curious what causes the trail in the olive oil.
I think slow-motion was a nice choice for the phenomena shown here. The deformation of the drop of nail polish is quite wonderful to watch.
Have you thought about using a different container to catch the pure flow phenomena without distractions of some lighting issues?
