The TPR and pectin inside are soft materials. Why is it called a grape, because it is surrounded by a very tough holey mesh bag, and the inside of the ball is tightly wrapped inside. You squeeze it with your hand. There is no place for the latex to swell, and you can pop out of the hole. One by one, many and many small balls will come out, just like a grape ball.
Another function is to vent the ball to squeeze the ball. No matter how crowded, the ball will not be broken until you reach the air.
