A University of Idaho employee was featured on the show, and he demonstrated a couple of his never-before-seen acts.
"I do something different with each one," said daredevil Brad Byers.
Moscow resident Brad Byers has been performing for about 40 years.
"I started out as a juggler, as a teenager," said Byers. "I'm still a juggler. And when I got out of high school, I started traveling with circuses."
When Byers got bored with juggling, he decided to branch out to more dangerous acts.
"I thought, what's the most impossible act in the world, and sword swallowing popped into my head," said Byers.
Now, he's best known for his sword swallowing abilities.
"I'm the only person in the world to swallow ten swords, one at a time, till all ten are down, and then twist them in my throat," said Byers.
He said he suffered some minor injuries during the learning stages, but now he's experienced enough to let other people push a sword down his throat for him.
"This is an antique Ford Model T truck axle," said Byers.
And he's always inventing new tricks.
"I take baby steps, and I just keep pushing my body to the limit," said Byers.
KLEW News was the first to see one of his newest acts--- swallowing a truck axle. We also got a sneak peak of the newest addition to his "Human Toolbox" act.
"With this hook, and that anchor, I will do my impression of a fishing trip gone horribly wrong," said Byers.
Byers said he loves performing and seeing the audience react to his stunts.
"I once had somebody faint in the second row during a performance," said Byers.
But he doesn't recommend the profession to prospective daredevils.
"Don't do it," said Byers. "It's very, very dangerous, you can mess yourself up for the rest of your life, and you have to be trained by a professional if you're going to proceed at all."
After Tuesday night's performance, the judges decided to send Byers to New York City for the next stage of the competition. Now, he'll need the viewers' votes to continue.
