The people behind the upcoming National Geographic show How Hard Can It Be? were recently spotted filming an episode for the show’s fall premier. The show is all about finding out if the fantastical things in movies and books can actually be done in real life.

Case in point: The production team wanted to see if re-creating Disney’s animated film UP!’s flying domicile was physically possible. Deemed almost impossible to do it with a real house, they built a lightweight 6' X 16' house 18' tall with 300 8' colored weather balloons  and launched it from an airfield outside L.A.

According to the show, "The entire experimental aircraft was more than 10 stories high, reached an altitude of over 10,000 feet, and flew for approximately one hour."

Check out the video below to see how they did it:

What other challenges do you think they should they try next?
