Sorry it took so long.

A quick and dirty idea that MIGHT help you pull this shot off:

- You can assign a path curve for your emitter to follow all within a 3d/2d fluid container. (i.e bendy-straw path)

To make your fluid emitter appear to collide with the insides of the straw geomerty, choose "Make Collide".

I know it is not that detailed of an answer, but it 's just an idea that I had.
Lemme know if that helped at all.
