Construction
Today’s footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry. The inside of the football is made up of a latex bladder which enables the football to be pressurized. The ball’s panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine.
