Found a thread where they discuss about it, they played with the glass and a ping pong ball:
Video of the experiment:
Taikonauts teach class on water buoyancy in absence of gravity
Mirror:
How!?
Gravity!
lol I love watching people who know absolutely nothing about science get freaked out by really basic shit like this.. Maybe you should watch the lesson and learn why / how they did this.
It's like having a gas lighter in the stone age and watching the natives lose their shit because they think you're magical.
An open jar full of water in an environment where every wall is filled with electronic equipment, and in zero g. They're one sneeze away from a major catastrophe; or they're openly mocking us.
It looks like it might be a higher viscosity liquid. Water would have done the same but I think it would be more likely to have come out of the container. Then again it could have been water. The surface tension would keep most if not all in the glass too. Low g environments are unintuitive at times.
The Chinese have invented artificial gravity. Or maybe super dense water.
I added the video related to that picture in the sticky comment.
