Look Ma, no Photoshop! You're looking at the largest balloon cluster flight - 300 weather balloons lifted this 16'x16' house into the air for an hour long flight. The feat was party of a new series for the National Geographic Channel called How Hard Can It Be?. Hard or not, it's pretty impressive by any standard!
You can see a ton more photos of the event at My Modern Met.
