Millions will watch live this Sunday when The Discovery Channel broadcasts Nik Wallenda as he walks on a two-inch thick wire at 8 p.m. ET. They will use a 10-second delay, according to a Discovery Channel spokesman.
Wallenda holds seven high wire world records including the biggest walk across a waterfall when he crossed Niagara Falls on TV last year.
But this time there won't be a safety harness.
Kate caught up with up him to watch him train, and ended up trying it out for herself. "I didn't tell my husband about it until I got home," she says.
