Two demonstrations in one experiment :
  • as the cloth absorbs water and gets thoroughly saturated with it, it starts to act as a siphon (as long as you keep the surface above the muddy water higher than the surface of the water in the other beaker
  • the fibres of the cloth function as a filter
The second picture shows that you already have decantation in the mud filled beaker (you have a clear supernatant).  Granule size in your mud is probably on the high side.
