World Record Free Solo – Insane Slacklining!

Daredevils have been tightrope walking and slacklining for ages. It’s one of the few performances that hasn’t changed over the years, making it very hard to break a world record in the extreme sport. Still, daredevil Spencer Seabrooke did just that on August 2. He slacklined across two cliffs in British Columbia for 290 meters. Terrifying!
