January 22, 2012 (Santee) -- Fourth grade students at an East County elementary school were treated to an extra special show-and-tell in January. A sampling of artifacts recovered from Titanic, 2.5 miles below the ocean’s surface, were shared with more than 130 enthusiastic Rio Seco Elementary students in Santee. The show-and-tell was a preview of Titanic: The Artifact Exhibition, opening Feb. 10, 2012 at the San Diego Natural History Museum.
