I love this video very much. Reaction videos are generally great for seeing people's reactions—the joy and surprise on their faces, the triumphant body language. In this one, you can't see a thing. But you can hear everything.
This is filmed in someone's apartment in the Saavedra neighborhood of Buenos Aires, and captures the moment Maxi Rodriguez's penalty kick put Argentina through to the World Cup final. As it does, the cameraperson pans out the window, just in time to hear the roar go up from the city. This is why international sports are incomparable—everyone is in it together.
