So there I was getting a glass of cloudy water from the tap cause I was thursty see and as I was about to drink it I noticed that is was fizzing. Naturally I began to pour it out but as I did, I was reminded of that old philosophical question: Is the glass half empty or half full? Is it merely a matter of perception or is there an actual answer? I'm leaning towards there being a definitive answer based on the action that led to the water being in it's half measurement state.
