Heartstopping footage of German kayaker Adrian Mattern rushing down a 128-foot-tall waterfall in Veracruz, Mexico. <br /><br />The video, shot on December 12, shows Mattern expertly navigating down the 'Big Banana falls' in the Mexcian jungle. <br /><br />"Help is far away and everything needs to be very well thought through in order to make this as safe as possible," Mattern told Newsflare. <br /><br />"Adrian had a good line and reappeared in the spray of the falls raising his fist and claiming the descent."<br /><br />"That waterfall also happens to be the vice record in kayaking!" he added.
