August 3 to August 6 the Smithsonian’s Lemelson Center is leading "Invention on the Mall - A Family Invention Festival".  It will take place in various Smithsonian Museums (National Museum of American History, National Air and Space Museum, National Museum of the American Indian, and National Museum of Natural History) on the National Mall in Washington D.C.

The weekend-long event will help the Lemelson Center kick off its second decade as a nationally recognized organization which documents, interprets, and disseminates information about invention and innovation.
