Its not that, either.  CSF has the same density as everything else and
won't flow by gravity inside a fluid-filled body. Hydrostatics is OK.

I believe the main movement is produced by the slight pressure at
which is is produced by the choroid plexus.  I have seen claims that
respiratory and circulatory movements can influence the flow.
