Most of the zero-g scenes in the SyFy series The Expanse appear to be done with good old cables, some CGI, and actors moving slowly.
But there is one scene at the very beginning of the first episode, where Julie Mao is trapped and weightless in a small room, and, notably, her hair appears weightless. An extended version of the scene is also seen in a flashback in episode 9.
How was that scene filmed? Water tank and color grading? Vomit comet flight? CG hair?
