    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.
