An octopus named Paul has successfully predicted the winner of each of Germany World Cup matches so far. Paul, who currently lives in a tank at an aquarium in Germany, even picked Serbia to beat Germany which has been one of the biggest upsets in the tournament thus far. So how's he doing it? Handlers basically place two clear boxes in his tank, one with Germany's flag and one with the opposing country's flag. They place shells and other treats inside both boxes and the box that Paul picks first is the winner. Until Germany gets knocked out of the tournament, the aquarium will continue to have Paul make his picks.
