Abstract

An improved entertaining balancing ball set includes a basis ball of a pre-determined outer diameter and a rolling ball of a smaller diameter. The basis ball includes one or more grooved orbits of which the shape could be branching, labyrinth-like, curving, extending, etc. The grooved orbits include a skewed side, one or more traps, a starting point on one end for each of grooved orbits, and a destination on the other end for each of grooved orbits. The rolling ball has a diameter that is determined based on the width of the groove orbits over which the rolling ball is to move within. The inside of the basis ball could be either hollow or solid.

Claims

exact text as granted — not AI-modified
1 . An improved entertaining balancing ball set, including
 a basis ball of a pre-determined outer diameter, wherein said basis ball includes an outer surface, and said outer surface further includes one or more grooved orbits, and   a rolling ball including a diameter determined by the width of said groove orbits.   
     
     
         2 . An improved entertaining balancing ball set as claimed in  claim 1 , wherein each of said grooved orbits include a skewed side. 
     
     
         3 . An improved entertaining balancing ball set as claimed in  claim 1 , wherein each of said grooved orbits include one or more traps. 
     
     
         4 . An improved entertaining balancing ball set as claimed in  claim 1 , wherein each of said grooved orbits include a starting point on one end for each of said grooved orbits, and a destination on the other end for each of said grooved orbits. 
     
     
         5 . An improved entertaining balancing ball set as claimed in  claim 1 , wherein the inside of said the basis ball is hollow. 
     
     
         6 . An improved entertaining balancing ball set as claimed in  claim 1 , wherein the inside of said the basis ball is solid.
