Luke Geissbühler and his son Max tied a video camera to a weather balloon and sent both more than 100,000 feet into the stratosphere. Ninety minutes later the camera floated back to earth with the help of a small parachute.

A spectacular seven-minute video of the voyage, posted on Vimeo, has become a viral success, garnering more than one million views since it was uploaded on Sept. 19.

Captured on their video? The curvature of the earth, the blackness of the upper atmosphere, and Amy Winehouse.
