Sure, you can't actually pet the leopard, or hang out with Buzz Aldrin circa 1969, but that's okay -- because one would maul you, and the other would be way confused as you suffocated in the deadly vacuum of space.
So, National Geographic's Augmented Reality PR stunt that's been traveling to various locations is actually really cool. All of the fun of Nat Geo bringing the experience of history and science to your local mall, without any of it killing your face.
Win-win.
