deformation of a thin membrane (spherical shaped)

I am trying to simulate the deformation of a very thin spherical object (with very low Young's modulus) that has fluid inside and outside (like a balloon filled with water). The fluid density inside is higher than the outside.
I will apply surface stress on one side and look at the deformation.
Does anybody have any suggestions to which module to use, or where to start? I was thinking of using solid to create a very thin object. However the fluid inside and outside (sugar solution) is nearly incompressible with very small finite modulus.
The ultimate goal is to find mechanical characteristics of the membrane like material. The force is applied on the membrane.

I appreciate any advice related to use of proper Comsol modules.
