Thanks Paul. :)
Just as a thought does anyone know if fly regurgitant (is that a word?) has enzymes in it or is it microbe driven from the point of view of dissolving food stuffs?
Just wondering if the original "aid to digestion" theory could be spot on if blowing bubbles helps concentrate (by evaporation) whatever helps to dissolve their food when they do regurgitate on it.
