The Hope Diamond.  It really wasn't what I expected.  It just looks like the Heart of the Ocean from Titanic!  The little stand it's on rotates around to each side of the case every few minutes to give everyone an equal look.
These next two are from the National Museum of Natural History.  This is the skeleton of a pre-Ice Age squirrel.
Obviously, a triceratops lol.
These next three are from the National Air and Space Museum.  This is the first airplane, built and flown by the Wright Brothers in 1903.  It's a lot bigger than you'd suspect.
