How Long You'd Last at Every Depth of the Ocean

How long would you last at every depth of the ocean? We start with one breath at 10 meters and end at the bottom of the Challenger Deep, nearly 11 kilometers down. At every depth you get the best gear humans have ever used there, from a scuba tank to a submarine, and we find out exactly how long it keeps you alive. 0:00 How deep is the ocean? 0:24 10 Meters: The Squeeze 1:13 30 Meters: The Martini 2:07 66 Meters: Poison Air 2:53 100 Meters: One Breath 3:56 332 Meters: 13 Hours 4:47 534 Meters: Moving In 5:45 1,000 Meters: The Midnight Zone 6:49 2,992 Meters: The Whale 7:41 3,800 Meters: Titanic 8:39 6,000 Meters: The Abyss 9:37 8,336 Meters: The Last Fish 10:33 10,935 Meters: Challenger Deep 11:42 So how long would you last?
