Tiny whirlpool/vortex bending light

I am trying to build a vortex in my plantpond. This to get oxygen in the water, and also to keep the surface clean.
Getting a stable vortex is not easy, but I got close. Problem is each time trying to get it better I have to destroy the old construction.
There is wind, waterheight and other factors making it difficult, but I'm having fun with it.

Anyway, I noticed how the vortex made the sunlight refract in such a way that it appears to bend.
Was a bit surprised to see light being bend in such a way that it is visibly bend.
Probably nothing really special, still I found it very nice to see. So I recorded it.

all the fishes and salamanders will love the turns ...

The pond is raised, so the salamanders should climb a vertical wall to get in, which they can't.
