“The people behind the upcoming National Geographic show How Hard Can It Be? were recently spotted filming an episode for the show’s Fall 2011 expected premier. Exploring the many facets of possibility, they wanted to see if recreating Disney’s animated film Up was physically possible. Deemed almost impossible to do it with a real house, they set up a lighter weighted version and set it off in the California desert with 300 weather balloons. Coverage of the event is shown below.”
