Fluid Variations

Hi everyone, just started a project which I hope to explore some fluid/water options, I have never tried this before so I hope this makes sense.

I hope to use two different types of water effects.

Firstly I need to rain water down on a surface, and then the water to come together and roll off - essentially if you imagine how water usually works on a surface - this is it!

The main question comes to my second requirement, for this I want to do the same thing, but once the water has landed I wanted it to stick and bobble similar to the effect seen on a non-stick frying pan.

I then want to have the two - ideally happening on different areas on the surface to show the difference.

So - in short, can I create a normal rain effect and then a ‘non-stick’ effect within Blender?

Deepest thanks in advance!
