Jason DiSanto navigates an obstacle course in an electric-powered wheelchair by issuing commands with a magnetic tongue piercing. The 50-meter-long course, at the Shepherd Center in Atlanta, Ga., included 13 turns and 24 obstacles, requiring tongue drive users to make U-turns, move in reverse and negotiate a loop.
