Real Life Version of Up by National Geographic

Is it really possible to lift a house off the ground with helium balloons? In the real-life version of Pixar’s animated hit film Up, National Geographic aimed to find out, and ended up setting a world record for the largest balloon cluster flight ever attempted. 300 colored weather balloons were used to lift up a 16′ X 16′ house, 18′ tall to reach an altitude of over 10,000 feet for approximately one hour.
