The Walter E. Washington Convention Center was once again the host for the Worlds's largest celebration of Science, Technology, Education, and Math (STEM) . Over a three day period, more than 350,000 people attended the more than 3,000 exhibitions that covered the entire 2.3 million square feet of exhibition space. The Carnegie Institution, as always, manned a booth that displayed some of the more exciting ideas that could captivate young people. Carnegie's displays were organized this year by Natasha Metzler (Headquarters) and Michelle Scholtes (GL).
