Daredevil falling off a highwire and being engulfed by a giant wave

A group of slackliners planned the elaborate stunt and connected a wire between two famous cliffs in Nazare, Portugal, a spot known for its huge waves.

Daring Emerson Machado, a 28-year-old from Brazil, braved the line but said the stunt was "not crazy."

News Nation appeals its viewers not to try this stunt.
