From Wired via Big Picture blog: "The two students (from MIT, of course) put together a low-budget rig to fly a camera high enough to photograph the curvature of the Earth. Instead of rockets, boosters and expensive control systems, they filled a weather balloon with helium and hung a styrofoam beer cooler underneath to carry a cheap Canon A470 compact camera. Instant hand warmers kept things from freezing up and made sure the batteries stayed warm enough to work.
Of course, all this would be pointless if the guys couldn’t find the rig when it landed, so they dropped a prepaid GPS-equipped cellphone inside the box for tracking. Total cost, including duct tape? $148...

The picture you see above was shot from around 93,000 feet, just shy of 18 miles high. It’s short of the widely-accepted Kármán line, which is at 100km (62 miles) up, but it’s in the stratosphere, and it’s still impressive. To give you an idea of how high that is, when the balloon burst, the beer-cooler took 40 minutes to come back to Earth."

Yeah
Bryan had to work late all week to plan to shoot that cooler down in the event it was headed for a major population center.
Good practice no doubt!
Of course, you knew I was totally joking. :)
I AM surprised, however, that these guys didn't get prosecuted for illegal entry/use of air space.
