Watch a math magician, light dancers steal the 'America's Got Talent' stage

Move over singing auditions, it's time for a bit of magic and dance.

25-year-old Tom London brought his mathematical magic trick to the America's Got Talent stage during his audition, which aired Tuesday on NBC -- and let's just say, people were impressed.

“Ladies and gentlemen, I want to try and do something that’s never been done before,” he said, starting his audition.

He then asked for audience members to hold up their phones, which lit up in different colors.

“How are you doing that?” judge Howie Mandel asked, stumped.

“In today’s world, we’re all connected through our cell phones,” London continued. “But what I want to show you is that we’re actually all connected on a far deeper level.”

He then asked judge Simon Cowell to select three audience members with glowing phone screens. Once onstage, London asked each of them a number-related question and had Tyra Banks, the show’s host, add them to her phone’s calculator.

The result? What seems to be a completely random number: 73,928,547.

“OK guys, we’ve got this random number here,” the magician explained. “But there’s something bigger going on, something impossible, something magical.”

Then, tying the whole trick together, London stumped the crowd yet again by playing a video clip of himself hours before his audition holding up the same number.

We may need a minute to figure this one out.

Another crowd-favorite audition came courtesy of the dance group Light Balance, who won over the audience with their creative number that paired music to light-up costumes and props.

After their performance, host Tyra Banks took to the stage to share her thoughts.

"I'm amazed by you guys," she said. "Wasn't that incredible? Like, crazy good? Blew my mind good? I feel you guys so so much."

She felt the dance group so much that she decided to give them a golden buzzer, which sends them straight to the live show.
