Non-standard sport projectiles, in accordance with this invention, include
at least one linear through hole. As this non-standard sport projectile
passes through the air, after being hit by, for example, a golf club, the
non-standard sport projectile spins. When the above-mentioned through
hole is generally aligned with the projectile's direction of flight, air
passes through the through hole, and the aerodynamic characteristics of
the non-standard sport projectile are enhanced. When the through hole is
not aligned with the projectiles direction of flight the aerodynamic
characteristics are reduced. As a result, the non-standard sport
projectile experiences rapidly repeating intervals of relatively high
aerodynamic flight and relatively low aerodynamic flight as the
non-standard sport projectile spins around the center cross section of
the through hole.
