How do you fix a stress ball?

To fix a stress ball, first, identify the puncture or tear in the material. If it's a small hole, you can use a strong adhesive or super glue to seal it. For larger tears, consider using a patch of fabric or a balloon piece to cover the hole, securing it with glue. If the stress ball has lost its filling, you can refill it with rice, flour, or similar materials, then seal it tightly.
