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. Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality. The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine. The size of a football is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by π gives about 22 cm for a diameter.
This ball uses installed sensors in it. These sensors collects data and shares it to your iOs and Android app via Bluetooth.

In 1838, Charles Goodyear introduced vulcanized rubber, which dramatically improved the football. Vulcanisation is the treatment of rubber to give it certain qualities such as strength, elasticity, and resistance to solvents. Vulcanisation of rubber also helps the football resist moderate heat and cold. Vulcanisation helped create inflatable bladders that pressurize the outer panel arrangement of the football. Charles Goodyear's innovation increased the bounce ability of the ball and made it easier to kick. Most balls of this time had tanned leather with eighteen sections stitched together. These were arranged in six panels of three strips each.
The most commonly used materials for casing are PolyUrethane(PU) and PolyVinyl Carbonate (PVC), synthetic leather or a combination of PU and PVC. You can distinguish the type of casing used by touch. Balls that uses PVC usually have a hard exterior but are cheap and durable. PU cased balls are softer to the touch, high in quality and more responsive than PVC balls. Synthetic leather balls offer increased control hence ideal for professional matches or high-level playing. You will also notice a glossy finish on all soccer balls. This comes in handy in minimizing scuffing and water damage to the balls.
I bought this soccer ball for my granddaughters for Christmas. It arrived inflated, which concerned me. My husband inflated it with no problem and it is just fine. The ball is bigger than I thought it would be, but that is because it is a size 5 and the girls use a size 4. I didn't see the different sizes when I ordered it. It does light up very nicely and the girls love it. They got outdoor soccer nets for Christmas and I thought this ball would be great as they play late in the day. They can't wait to put it to use.

The soccer ball has gone through various changes just as the football game. As opposed to yesterday’s football ball that had stitches and seams and the classic black and white design, today’s soccer balls are designed with the latest technology that lets the ball bend more, fly quicker and also dip harder. Besides, they are quite soft that they let players kick the ball further without risking injuries. https://www.youtube.com/watch?v=DGp37du0xbQ
