You already saw the photos of the real life Up! house, but here's the video. National Geographic has sent us raw footage from their new program How Hard Can It Be? - which premieres later this year. It looks amazing.
The 5m by 5m wooden house was hooked to 300 weather balloons full of helium, to a total height of 10 storeys. After being set free in a private Los Angeles air field, it reached more than 10,000 feet (3000m) during its one-hour flight.
