Adjustable weight toy ball

A toy comprising:

• a) a ball having an exterior surface, an interior, a water chamber located in the ball interior, a water fill aperture located in the ball exterior surface and in fluid communication with the water chamber, a proximal recess located in the exterior surface, a proximal rope aperture located in the proximal recess, a proximal cap in the form of a proximal knob and comprising threads and a hollow interior and seated in the proximal recess, a distal recess located in the exterior surface, a distal rope aperture located in the distal recess and located approximately 150 degrees to 180 degrees relative to the proximal rope aperture, a distal cap in the form of a distal knob and comprising threads and a hollow interior and seated in the distal recess, a tube traversing the ball interior and having a proximal end adjacent to the proximal rope aperture and a distal end adjacent to the distal rope aperture, the proximal end of the tube comprising threads mating with the proximal cap threads, a proximal o-ring surrounding the proximal cap, the proximal o-ring seated in the proximal recess, the distal end of the tube comprising threads mating with the distal cap threads, and a distal o-ring surrounding the distal cap, the distal o-ring seated in the distal recess;
• b) a rope having a proximal end, a distal end, and a length extending from the proximal end to the distal end, the rope located in the tube and extending through the ball interior,
• wherein the rope further comprises a proximal knot proximal to the proximal cap and a distal knot distal to the distal cap and the proximal knot cannot pass through the proximal rope aperture and the distal knot cannot pass through the distal rope aperture, and
• further wherein the tube creates a seal so that, when water is located in the water chamber, the water from the water chamber cannot come into contact with the rope.
