He built a bike with wheels of ice. He created a metal suit that can withstand fireworks. So what does amateur inventor Colin Furze have in store this time?

He sent 12 balloons up into the air, each carrying between two and four HTC smartphones, which were set to record the experience. They reached higher than 100,000 feet, according to Furze. That means they made it into the Earth's stratosphere, or the second layer of atmosphere.

So we may now have what very well may be the first phone camera footage taken from an altitude above 100,000 feet.

He sent them all the way up there in specially designed boxes, so they could survive subzero temperatures on their journey. Eventually, of course, the balloons popped, sending the phones tumbling back to the ground.

The video claims that all of the phones survived the trip.

There's a bonus in the video, too. On the way up, Furze remotely launched fireworks above the clouds — as high as 20,000 feet from the ground. (Any higher than that, though, and the fireworks wouldn't go off, according to Furze.)

Previously, Furze told Mashable that he's able to fund such wacky projects thanks to the large following of his videos.

"It used to be just a hobby, but now I earn enough from YouTube," he said. "Now I do this all day — it's much more fun than plumbing."
