The discussion highlights the significant differences in behavior between wet and dry sphere splashes, emphasizing the impact of surface tension and fluid dynamics. A video is shared to visually demonstrate these differences, with a warning about the accompanying music. Participants express interest in the scientific principles behind the phenomena, referencing a research paper that explores current theories on sphere splashes. The paper provides a deeper understanding of the mechanics involved in these splash patterns. Overall, the conversation centers on the fascinating interplay of physics in fluid behavior.

TL;DR
This phenomenon was first observed by A. M. Worthington in 1897.
Caution: This video has music. Turn sound off before watching if this bothers you!

Thread 'Why higher speeds need more power if backward force is the same?'
Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same? I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
