You can try: sphere_sweep, spline + blob, isosurface, torus.

The buble should protude a little bit in the meniscus, ie. push the near part a small
bit upward. 
You may need to use a blob or an isosurface for the whole thea.

Using some media will enable to modulate the density around the leaves. You can then
add some 
turbulence to that variable density. That combined with fade_color fade_distance can
get prety 
realistic.
