Abstract
A variable flight toy having a plurality of strips constructed of a resilient material folded and secured proximate their midpoints to form alternating loops with ends centrally gathered to radially extend the ends and loops to form a ball, which, when struck, the loops and ends provide non-uniform aerodynamic resistance to the flight of the ball.
