Do you remember that little floating house from the hit movie “Up“? Well the guys over at the Discovery channel have made an actual version of the famous Up house and guess what, it floats with balloons! Of course the interior isn’t much to look at but still National Geographic have managed to lift the 16x16x18′ house to an incredible altitude of over 10,000 feet. It used 300 8′ helium balloons and astonishingly flew for over an hour.
