🙂 A close examination of the first photo reveals that Lawrence’s finger is not actually touching the water and therefore he did not actually sample it :whistle: . I think this is because he knows that using the sensory method, one must guzzle and swill one liter of the sample solution at least 5 times to get an accurate reading – given the looks of the peat swamp water :S, I cannot say I blame him for the slightly diminished sampling technique :lol:.
