High-wire artist Nik Wallenda crossed Nicauragua's active Masaya volcano during the ABC special Volcano Live! Wednesday night. And he had to worry about a lot more than just keeping his balance.
This volcano is one of only 8 volcanoes in the world to have a lava lake, filled 2,000 degree molten earth. The volcano also emits a toxic fog that is made up of hydrogen fluoride, hydrogen sulfide, hydrochloric acid, sulfur dioxide, and carbon dioxide gasses. Which required that the high-wire cable be coated in special material to keep from corroding.
Wallenda wore a gas mask and sealed goggles to keep the toxic fumes from burning and incapacitating him. Despite the safety precautions, he said that the gasses managed to burn his eyes.
At a height of 1,800 ft, this was Wallenda's highest walk. He later admitted it was also his windiest. There was one point during the walk in which viewers could really see Wallenda battling the wind.
The entire crossing took Wallenda a little over 31 minutes. He spent much of that time praying, as well as pitching his new book Facing Fear. When he did finally finish the walk, he was created to hugs, cheers, and place in the history books.
