There is a fine line between being a daredevil and being damn near suicidal and Spencer Seabrooke just walked that line in record breaking fashion.
On August 2 Spencer broke the world record for the longest solo slackline walk when he went across a gorge almost 1000 feet in the air with no safety line attached.
Slackline walking is like tightrope walking, but the line is loose and moves around ... because walking across a steady tightrope is too easy, apparently.
Check out the crazy footage that will give you vertigo.
