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.
Changes in temperature will also affect the inflation level of the soccer ball. Extreme heat or extreme cold will alter the shape of the bladder and this will affect the integrity of the soccer ball. Although it doesn’t seem like you could reach an extreme temperature that could do this to a soccer ball, just leaving a ball in your trunk or the back of a van on a hot Summer’s day will do it.
I purchased light-up-soccer ball for my grandson for his father's birthday (Brooks Bowers) who has officiated games, played games and loved soccer for many years. And I have a picture of my grandson (Kieran) smiling at the rolling lighted ball after he kicked it. I thought it a well made, worked as it arrived with batteries already installed and a wonderful gift. To my surprise my grandson at age 3 is already attending soccer camps for young children.

Crafted by Adidas, the Telstar 18 is the official ball of the FIFA World Cup. Drawing inspiration from the company's first World Cup match ball, which debuted at the 1970 tournament in Mexico, the new ball reimagines the 12 black panels on an otherwise white design. Fun fact: the iconic original black and white ball was made that way to be more visible for black-and-white TV viewers, and it was dubbed the "star of television."
