Properties and Behavior of Water

Jackie Sherry from the Athens-Clarke County Public Utilities Department discusses the unique properties of water, including cohesion, adhesion, and surface tension. Through various activities, viewers learn how these properties allow water to defy gravity and perform interesting feats. The video emphasizes the importance of water conservation and provides practical tips for reducing water usage.
