I am just starting to experiment with water drop photography. I really like this type of photography because there is no way of staging the same picture twice. They will always give a different result without any parameters changing. I just used a little plastic beaker filled with water. The drops consisted of nine parts milk to one part xanthan gum. I used two Godox remote flashes either side of the image on 1/128 power.
