I cannot see surface tension having an effect in a closed system with pressure above 1 atmoshere absolute- (see capillarity, adhesion, cohesion), and I cannot see viscosity having an effect in a non-flowing situation. I can see the expansion/contraction as a sort of 'vibration', jiggling things loose.

If the AF solution were thixotropic, its viscosity would lessen over time, explaining the ooze factor.
