1. An object, comprising:
- a solid generally spherical structure having a diameter with a range of about two inches to about six inches, said structure including an outer surface defining a generally equatorial-circumferentially-extending groove dividing said structure into a first hemisphere and a second hemisphere, said outer surface including a plurality of slots in said first hemisphere extending from said groove to a pole of said first hemisphere.

Abstract
An apparatus that is adapted for enhanced curving when thrown specifically designed to aid in throwing to produce a curve effect and a method for throwing that enhances a curved trajectory. The object includes a solid generally spherical structure having a diameter with a range of about two inches to about six inches, the structure including an outer surface defining a generally equatorial-circumferentially-extending groove dividing the structure into a first hemisphere and a second hemisphere, the outer surface including a plurality of slots in the first hemisphere extending from the groove to a pole of the first hemisphere.

10. A ball, comprising:
-
a solid generally spherical structure having a diameter in a range of about two inches to about six inches, said structure including an outer surface defining a generally equatorial-circumferentially-extending groove, continuous around a great circle equator, dividing said structure into a first hemisphere and a second hemisphere, said outer surface including a plurality of longitudinally-extending slots in said first hemisphere extending from said groove to a pole of said first hemisphere; wherein said structure consists essentially of a low-density material; and wherein said groove has a depth in a range of about two millimeters to about two inches and a width in a range of about two millimeters to about two inches. - View Dependent Claims (11, 12)

13. A method, comprising:
-
a) throwing an object, said object including a solid generally spherical structure having a diameter with a range of about two inches to about six inches, said structure including an outer surface defining a generally equatorial-circumferentially-extending groove dividing said structure into a first hemisphere and a second hemisphere, said outer surface including a plurality of slots in said first hemisphere extending from said groove to a pole of said first hemisphere; and b) imparting a spin to said object while throwing to rotate said object about said pole wherein said groove does not significantly precess and appears to a thrower as a generally straight line perpendicular to an axis of rotation wherein said object curves generally in a direction of said first hemisphere.
