Nik Wallenda Is Set To Walk Over A Live Volcano

Highwire daredevil Nik Wallenda plans to walk over an active volcano in Nicaragua.

Of course, it will be televised. You can tune in Wednesday at 8 p.m. Eastern for the ABC special called "Volcano Live! with Nik Wallenda." Wallenda will attempt an 18-hundred foot walk over the Masaya volcano, a spectacle ABC calls the longest and highest highwire walk ever attempted.

Wallenda says the walk over a lake of lava will be the most dangerous he's ever attempted.
