Transcript

Have you ever had the urge to sneak behind the cordoned off areas of a museum? Or roam the halls after closing time? The Smithsonian's flagship podcast, Side Door, will sneak you behind the scenes of the world's largest museum and research complex. Come learn about the ghosts that supposedly walk the museum halls after dark, how a train robbery gave rise to criminal forensics, why leeches are actually the coolest thing ever, and how to get away with murder in the Arctic. Maybe. You'll discover stories of history, science, art, and culture you won't find in a display case. You can listen to Side Door wherever you get your podcasts. Or find us online at si.edu slash sidedoor.
