These balls are great for indoor games and outdoor water fights.
Using scissors cut used carpet padding into a 1 square foot piece, then cut the square into twenty-four ½-inch wide strips. Cut each strip in half to make forty-eight 6-inch strips.
Stack the strips centered over a twist tie laying flat on a hard, stable surface. Tightly twist the tie around the center of the stack. Pull, twist and turn the strips until you have a ball.
