New insights on antibubbles

Have you ever heard of antibubbles? Simply put, they are the material opposite of soap bubbles. They consist of liquid inside, which is separated from the surrounding liquid, typically the same liquid, by a thin layer of air. Everyone we have told this to so far has said: “Wow, is that real?” Due to this composition, antibubbles have some physically interesting properties that can be investigated using very simple methods. In our research, we used a reproducible experimental set-up to investigate certain properties such as oscillation, the thickness of the air layer and, depending on the parameters, the diameter, the sinking depth and the probability of the formation of an antibubble. We addressed previously unexplored questions and achieved new results in this field of research.
