Many people have a fear of being confined in small spaces. And it's safe to say that everyone has a fear of drowning. People with both of these fears probably won't like this video, in which a couple of spelunkers are exploring a cave that starts filling with water.
Watch as they remain somewhat calm while trying to make their way back out of the cave, recording the entire thing with GoPro cameras so they can look back fondly and laugh some day. Now, the video cuts off before the last guy makes it out of the cave and he disappears. We've been debating all morning whether he survived or not.
