How Your World Works

If you’ve ever seen a Cirque du Soleil show, or perhaps Marvel Universe Live, there’s a good chance you’ve seen the work of Brett Copes. He’s a rigger—one of the guys who sets up the complicated stage apparatus that lets performers fly through the air—safely—while looking supremely cool. On today’s show, he explains the technical details that make it possible, including the reason a 150 pound acrobat may in practice weigh half a ton.
