I thought that was just a quirk in the simulation which was just trying to simulate a wave bouncing back and forth on the walls. Simulating surface tension would be too much for this.

All the good _new_ content is either censored or no longer allowed on youtube, so its falling back on older videos because that's all thats left. The second factor is that youtube recommends things based on _category_ rather than similar watchers like it used to. So once an old video starts to go even a little bit viral KZbin gets it out to pretty much everyone who has ever looked at that category.
