Why does drinking water often look cloudy when first taken from a faucet and then clear up?
The cloudy water is caused by tiny air bubbles in the water similar to the gas bubbles in carbonated soft drinks. After a while, the bubbles rise to the top and are gone. This type of cloudiness occurs more often in the winter when the drinking water is cold.
