Watch 25-year-old extreme sports athlete Mich Kemeter set the world record for the longest slacklining, or "waterlining," walk as he tiptoes 820 feet above the Green Lake in Tragoess, Austria. For 20 days, Kemeter attempted to break the record with no success, but after several falls he completed the impressive walk across the slackline in 19 minutes.

Kemeter climbs, slacklines and base jumps all over the world, and set the previous slackline record at 728 feet in the same location last year. He hopes to keep pushing the boundaries to walk an even longer line soon.
