The collection at New York City's American Museum of Natural History contains 33 million specimens, only a fraction of which are on display. In its new series, Shelf Life, the museum is opening its doors—and its drawers—to show off some of the things the public doesn't typically see. The monthly videos will also feature interviews with museum scientists; you can watch the first one above.

Having seen some of the awesome things behind the scenes at the museum ourselves, trust us when we say you'll want to watch.
