For anyone that has seen the adorable Disney/Pixar film, Up!, you will be familiar with the character Mr. Fredrickson and the story line of his flying house lifted up by a ton of balloons. Well, as part of a campaign to promote their new show, "How Hard Can It Be?", National Geographic recreated the house from the movie!!!! They have about 300 giant helium filled balloons that lifts the house up to 10,000 ft for a good hour.
Granted, I don't know what the house was made of or if there was even anything in there, but I'm sure they built the house as economically as possible. It's still awesome though. View more pics at the National Geographic blog.
