Abstract
A ball includes a ball body having a spherical surface, and at least one projection extending from the surface of the ball body. The projection extends in such a manner that the projection forcibly separates a laminar boundary layer generated on the surface of the ball body, and transitions the laminar boundary layer to a turbulent boundary layer.
