Abstract
We often overlook the little things in life; by their very nature it is simply more challenging for them to strike our attention. However, as is often the case with the unassuming, when you decide to give them your attention, you will find an entire world of vibrant and exciting discoveries waiting to be made. Such was the case with my research on droplet impact, an unassuming phenomenon found in numerous natural and industrial processes, such as rainfall and additive manufacturing. As I dove into this phenomenon, I found that there exists a wide variety of striking and sometimes wild behaviors that droplets will partake in as they impact a surface. Often the droplet’s dynamics defy what I expect, even what seems physically possible. In these images of a progressing hollow non-Newtonian droplet impact, the droplet becomes a lava lamp-like tendril that looks to me like an otherworldly cyclops. Yet, as fantastic as the impact may seem, there is nothing at play besides the laws of physics. In this way, my research has been a lovely reminder that nature is full of wonder, if only you take the time to look for it, even in the places you may least expect.
