What is it about?
The bubble is very strange in viscoelastic fluid, for example, the shape has a sharp tail, the wake of the bubble flows downward, when the volume is greater than the critical volume, the bubble velocity transition and other phenomena. The author discusses the formation mechanism of these strange phenomena.

Why is it important?
The results can lay a theoretical foundation for the study of gas-liquid two-phase flow involving viscoelastic fluids. Such as the displacement process of oil extraction.
Perspectives
I hope that through this article, people will be interested in some of the strange bubble phenomena in nature and industry, and carefully observe these strange phenomena, and think about the causes of these strange phenomena.
