B Bubble of water in zero gravity

  1. Apr 5, 2016 #1
    What if you were in a spaceship in outer space and had a sphere filled with water and some fish in it and then carefully removed the shell, leaving behind only a bubble of water. Would the water hold together and could the fish would swim outside the bubble and suffocate?

    Yes, because of surface tension. You can find videos of this.

    This could happen. An interesting question would be, if it can swim back to the water through the air. Or if a dolphin, which can breathe air, would learn to swim through air in zero-g.
