While watching the Pixar epic Up, in-between not pretending to have a gobstopper-sized lump in our throats we were also debating the logistics of whether a house could actually rely on balloons alone to fly.
Looks like we weren't the only ones. As part of a new series, those National Geographic geniuses (more proof here) decided to put the idea to the test in the far less exciting real world.
On Saturday morning they launched a 16 ft by 16 ft house with 300 balloons and set a new world record for the largest balloon cluster flight ever attempted, travelling to over 10,000 feet.
Admittedly, they cheated a bit. The house was lightweight and contained just a couple of people and no actual belongings and the balloons were 8 ft tall weather balloons, consuming a tank of helium a piece. But we're willing to forgive them for all this and instead look forward to their next Pixar mythbuster which sees them try and bring toys to life. We hope.
The stunt was part of a show called How Hard Can It Be? coming later this year.
