Project leader Mike Cassidy explained how people on the ground would receive the Internet.
"For someone on the ground to use the Loon service, they need a small antenna about the size of a softball on the side of their house, and they just plug their computer into that antenna, and they get internet from the sky," Cassidy said.
The first person to get Google Balloon Internet access this week was Charles Nimmo, a farmer and entrepreneur in the small town of Leeston, New Zealand.
He was one of 50 locals who signed up to be a tester for a project that was so secret, no one would explain to them what was happening.
