This 3-minute Flash video by PBS Zoom demonstrates how temperature affects the density of water. A middle school student demonstrates the concept by placing a one-liter bottle of cold water directly atop a second one-liter bottle of red-colored warm water. Watch the warm red water, which is less dense, rise visibly through the mouth of each bottle to the top of the cold water. The student then performs a second "control" experiment in which both bottles contain cold water (no water movement is observed).
