Go down to your local Apple Store and you might just see this wonderful display for the new MacBook Air. Channeling Pixar’s Up, the display features a single helium balloon dangling aloft an 11-inch MacBook Air.
All is not as it seems, of course: nearly invisible fishing wire is being employed to create the illusion. The Air’s light, of course, but not so light that it can be lifted by a child’s balloon.
Still, this calls for an experiment: I wonder who out there is brave enough to figure out how many balloons are needed to send an Air into the stratosphere and willing to back up their math by lending their notebook and its iSight camera to the cause?
