Interesting to see your set-up.
What oil do you use, and have you found different oils give different results?

I will echo PhilT2's thankfulness. I have practiced with a frying pan but I guess cd's offer better reflections.

Hi all 
Some additional information
1. A glass bowl illuminated from below is ideal.
2. Water depth at least 2 cm, so that the bottom of the bowl is no longer sharp. Aperture approx. 5.6
3. Coloured light (continuous light = LED) from below gives good results. A CD automatically delivers "rainbow colours", however, only in a narrow area. Therefore a macro at 1:2 is ideal.
4. exposure time shorter than 1/100 to stop water/oil movements.
5. I tried different oils, what a mess to get everything clean again.
6. the following procedure worked best:
- Fill in clean water. Water from the tap can contain fluff or particles, which you can see clearly later.
- Fill in a little oil (e.g. sunflower oil), pipette, syringe or directly from the bottle.
- Stir the whole carefully until many single drops form.
- Wait !!! until the movements have calmed down and small "islands" with groups of drops have formed.
- Move the camera / glass bowl so that the drops are in the field of vision.
- Adjust Sharpness / CD / light and adjust lighting / colors until a good photo is possible.
- Photograph as long as the oil islands do not begin to wander through thermal movements.
Good luck

Many thanks for all the additional information and for sharing the whole procedure with us!
