This is a ball I made that took working on it 10 hours a week for 4 years to complete. It's probably the only type of ball of its kind and is doubtful any ball of its size can be made.
It is 52,750 standard size gem paperclips that are straightened, curled, and interlinked with no adhesives or support structure in the center of any kind. It weighs 42.20 lbs.
