# Honey, suspending gold flakes

I have a jar of honey that has a load of gold flakes suspended in it. It has been sat still for 24 hours and the flakes have risen to the surface. At least the bigger parts and the small ones stayed as they were. Any ideas as to the physics behind this and also if its possible to prevent the bigger ones from rising to the surface?

The difficulty is that gold foil is very thin, $0.001$ inch or less. When added to honey, an air bubble often is attached. Air floats.
