On sunshiny summer mornings the grass is often wet with dew. There may be drops of dew on flowers and bushes, and spider webs , too. The drops of dew sparkle like jewels when the sun shines on them. Drops of dew look like drops of rain, but they do not fall from clouds as raindrops do. They are formed from the water vapor in the air when moist air strikes a cold object. Dew does not stay on very long after the sun comes up. The grass and other things on which the dew has formed soon get warm Then the dew changes into water vapor again This same water vapor may become dew again the next night if the weather is calm and fair.
