Nik Wallenda has announced that he will be crossing an active volcano as part of his next stunt. The high wire expert will be crossing the Masaya Volcano in Nicaragua in March. The volcano has been dubbed “The Mouth of Hell” and due to the gasses it emits, Wallenda will have to wear a mask. The gases will also make it difficult for him to breath and see. "It is crazy, but again, when I do this stuff it is about continuing to push myself further," he told Inside Edition.
