Last month, a father and son from Brooklyn launched a homemade weather balloon, complete with HD video camera and iPhone, into the sky. It managed to reach the planet's stratosphere – that's 100,000 feet high – and safely fall back to Earth where the duo located it thanks to the iPhone's GPS. The whole thing was recorded on video. Pretty cool stuff.
According to the dad, Luke Geissbühler, no FAA approval was needed for the project. Watch the amazingly cool footage AFTER THE JUMP.
