ABSTRACT:
An amusement device, useful for ocular as well as hand-eye coordination exercises, takes the form of a rod with two removable end balls and a positionally adjustable intermediate ball. The rod is manipulated, twirled and juggled by means of two hand-held juggling wands in a variety of ways to effect different exercises. The balls are visibly distinguishable, preferably by color, to permit a user to focus on a specific ball while the rod is twirling and to catch the rod with that ball in a prescribed orientation. The adjustable ball permits selective adjustment of the center of gravity of the rod and correspondingly adjusts the rod trajectory so as to increase and decrease the difficulty of each exercise. One or more individuals can use the juggled rod, each holding a pair of juggling wands.
