If America had a giant attic…

the Smithsonian’s National Museum of American History would be it—and it provides the location for our most eclectic hunt. The galleries are packed with memorabilia representing all eras and aspects of American life, including Lincoln’s last top hat, Clinton’s saxophone, Julia Child’s kitchen, monstrous machines, two full-size locomotives, vintage cars, the original star-spangled banner that inspired the national anthem, Edison’s first bulb, and many more amazing artifacts.

But you don’t have to be a historian to enjoy this hunt. All you need is a sense of humor, sharp eyes and comfy shoes.

The hunt is played using the Watson Adventures app, which works on any phone and is quickly downloaded at the start of the game. The event takes about two and a half hours, with two hours of that as actual hunting time. Click on the button below to see the hunt calendar—and find more fun!
