Transcript for Man Ventures Into Mouth of Volcano With GoPro
I'm sure you're asking yourself, so, how do you go about diving into a volcano? Maybe the better question is, why on Earth would you want to? Tonight, we're taking you on a smoldering adventure into no man's land. He's the star of the video going viral tonight. Meeted adventurer Sam Kaufman. That's him right there. That lava, 2,000 degrees. That video, nearly 2 million views and counting. Sam likes to go where no man has gone before. Specifically, an exploding volcano. One of the most dangerous and inaccessible in the world. This is a crater in the south pacific. This is where Sam took a death-defying dive, wearing a special heat suit. It's so hot, he could only get close to the edge for a few seconds at a time. But even then, that suit got damaged and burnt. Along with a pair of guides, Sam's among the first to take the plunge, so, naturally, he captured it all on go pro. More humans have set foot on the moon than the fiery depths of this deadly volcano. Here's a good look at why. Even getting here is a nearly super human feat. A 1,200 foot decent. Filled with toxic smoke. So, why did Sam spend four days there and descend not once, but twice into the Gates of hell? He says the fear of this was overshadowed by the thrill of this. Like being on the surface of the sun. One false step and the whole plan could have gone up in flames. But Sam gives the thumb's up to this adventure of a lifetime. We have to admit, playing with fire never looked so cool. And all that fun is far from over. Sam will tell us what it's like to go all the way to hell and back in a live interview on "Good morning America" tomorrow.
