A ball, comprising:
- a hard shell of a predetermined size defining an internal volume and including a plurality of apertures therethrough;
- and
- a foam core disposed within the internal volume.
A method for teaching a person to hit a ball, comprising:
- providing a plurality of balls, each ball comprising:
- (i) a hard shell defining an internal volume and including a plurality of apertures therethrough, and (ii) a foam core disposed within the internal volume;
- and

A system, comprising:
- a plurality of balls, each ball comprising:
- (i) a hard shell defining an internal volume and including a plurality of apertures therethrough;
- and (ii) a foam core disposed within the internal volume,
- wherein the foam core of at least one of the plurality of balls is adapted to cause such ball to travel through air at a substantially different speed as compared to at least one other of the plurality of balls despite the balls being released at a substantially constant velocity.
