Last spring, Indi Cowie performed her freestyle soccer routine for 76,000 fans during halftime at a Chelsea-Manchester United match in Manchester. But standing backstage at the Green Hope High talent show in Cary, N.C., she was nervous.

They even spelled her name wrong in the event program. But this 16-year-old nobody does things that no other girl on the planet can do.
