Exhilaration beyond imaginable, intense concentration on a single point, and complete freedom of soul – all these things very accurately describe the art of highlining. Highlining is a branch of a new sport called slacklining, which involves walking on special webbing secured between two points. Andi Lewis is one of the most famous slackliners in the world, particularly due to his performance during Superbowl Halftime Show in 2012. He never fails to surprise people with an amazing stunt or a project. This time he and his friends have created a completely incredible hand-knitted hammock located hundreds of feet above the ground. Just getting to this hammock requires immense skills and bravery. But once you’re finally there, you can rest a while, before mustering up the courage to go back across a narrow line with nothing but thin air beneath your feet.
