National Geographic decided to see if it was possible to recreate a real life version of Pixar's Up. It was launched at dawn on March 5th by a team of engineers, scientists and 2 world class balloon pilots. Measuring 16ft x 16ft and 18ft high it took 300 balloons to lift it up the sky. The house even managed to break a world record for the largest balloon cluster flight ever attempted.
