how it was made:volleyball
An indoor volleyball is usually made out of synthetic leather that is good for hitting even surfaces, like a gym floor. The inside is pumped full with air. An outdoor, profes â¦ sional, or game volleyball is usually made out of real leather that is harder than the synthetic leather. This is also filled with air. Both volleyballs have cut panels of either synthetic leather or real leather that is stitched very tightly so that no air will escape. 8 people found this useful.
