Disney's "Up" house created in real life: Flies with 300 balloons (video)

The task of flying a real house with balloons proved difficult, but not completely impossible.

(PhysOrg.com) -- How hard can it be to lift a house with helium balloons? A National Geographic team of scientists, engineers, and balloon pilots has demonstrated how to achieve such a feat, which was filmed for a new TV series called “How Hard Can It Be?” They conclude that, although it’s very difficult, it’s not impossible.

It took the team about two weeks to plan, build, and lift the house into the air using balloons. They needed about 300 weather balloons, each of which inflated to a height of 8 feet, in order to lift the 2,000-pound, 16x16-foot yellow house.
