This Slack Liner Looks As Though He's Jumping Across Mountains As He Attempts World Record

No slackin' over here.

When you're attempting to beat a world record, it's best to do it with the most gorgeous backdrop you'll ever come across.

Slack liner Theo Sansin set what is thought to be a new world record while walking ever so carefully between The Rectory to Castleton Tower in Castle Valley, Utah.

The length of the walk was measured at 500 meters, or slightly over a quarter mile.

It is absolutely nuts.

It was no easy task setting up the slack line either, and his team deserves credit for this accomplishment.

He is so high up, it looks as if he's jumping across the top of the mountains.

So crazy. Watch the full video below.
