Tap water? Distilled water?
If there are two glasses of liquid in front of you, given one is tap water, one is distilled water, is there any methods to tell which is which?

Pour a few cm³ of the liquid to a clean test tube from each glass of liquid. Heat separately each of the two test tubes of liquid by using a burning flame.
The one that leaves a very small amount of solid (usually white in colour) is tap water, while the one leaves no solid is distilled water.資料來源： adam
