Extra scene feat. world record holder German swimmer Paul Biedermann and sports scientist Steve Haake. Paul set the world record in the 200 metre freestyle but his achievement has been disputed by those who think the record should really go to his revolutionary high tech full body suit: the X-Glide. The X-Glide covers a swimmer’s body in slippery polyurethane. Steve challenges Paul to beat the 200 metre freestyle record set in 1972 by the legendary Olympian Mark Spitz. To level the playing field, Paul will swim in a 1970s era pool wearing a recreation of Mark Spitz’s Speedo – a suit of normal fabric that covers very little of the body.
