Bubble in a Bottle

If you invert a bottle of fluid and open the cap, an air bubble rises through the neck of the bottle. As the bottle empties, more and more air-filled bubbles rise up the neck of the bottle, causing mixing, and beautiful Worthington jets. To capture the striking chaos of these physics, I filled a bottle with water and mineral oil (2:1 ratio of water to mineral oil), inverted the bottle, and removed the cap.

This video was captured on an Olympus OMD E-M10 Mark II mirrorless camera with the kit lens (an M. Zuiko Digital 14 – 42mm 1:3.5-5.6) at 120 frames per second and a focal length of 42mm.

    I really like how simple you left the other aspects of this assignment. Because the flow is so interesting in captivating, slowing it down was the perfect touch to your simple frame. Really well done!

    Hi Corey,

    I liked the experiment you chose to do and how you utilized slow motion in order to enhance the effect that you were trying to capture. I think the use of mineral oil was a great choice in not only making the effect more visible but also providing the additional small bubbles around the bottle. It really helps see how more air bubbles rise up to the neck of the bottle as the phenomenon develops.

    I really like the effect shown in this video. Your choice of bottle, background, lighting, and fluid really help visualize the fluid dynamics in a very clear way and the music choice accompanies the video quite well.
