Flip Sphere Motions

[zinogino 0]

Hey there,

I'm trying to replicate this setup: 
Liquid Sphere

Based on my scene, I have a sphere and the particles are generated from it with iso offset and particles from volume.

Within FLIP, I tried to control the velocity with pop forces (POP force, pop attractor and pop axis force) and got somewhat of a swirly motion but the in the reference video, towards the end you can see the fluid is ground around a torus like motion and the shape as well

Any pointers on achieving this?

HIP file attached included.

Thanks!
