In 2021 rafabridi 🇧🇷 achieved this incredible slackline walk at 1,901 m (6,236 ft) Rafa walked between two hot-air balloons above Praia Grande in Santa Catarina, Brazil. He crossed the 2.5-cm-wide (1-in) slackline barefoot, passing through the clouds at an altitude that took to him to twice the height of the Burj Khalia, the world’s tallest building. #slackline #hotairballoon #guinnessworldrecords
