• Question: Why is the water in space in a bubble? I know there is no gravity, but I don't see how anti-gravity would cause this.

      Well..because of the free-fall condition in the ISS ( the ISS is still kept by the gravity around Earth), we can experience things differently, like the balls of water. 🙂

      Technically, with gravity, everything will attract everything else like, a bit like magnets, but because most of the time Earth is the biggest thing, we don’t get to see the small things being attracted between themselves. This is what happens with the water.
      All the droplets are attracted to each other and the closer they get the more attracted they are. If you had the water on a piece of paper (2D), you would see all the drops getting closer and making a larger circular drop, but because you are in 3D the circle becomes a sphere…
      ….and this is exactly how planets and moon formed, from lots of dust and lumps of rocks, creating larger spherical objects…
