A football, soccer ball, or association football ball is the ball used in the sport of association football. The name of the ball varies according to whether the sport is called "football", "soccer", or "association football". The ball's spherical shape, as well as its size, weight, and material composition, are specified by Law 2 of the Laws of the Game maintained by the International Football Association Board. Additional, more stringent, standards are specified by FIFA and subordinate governing bodies for the balls used in the competitions they sanction.
During the game, there were two different balls used: the 12 panel Argentine players model like this one and a T-shaped model used by Uruguay. There’s speculation the use of the two different balls actually played a part in the outcome of the game. Argentina started using this 12-panel ball and entered the halftime with a 2-1 lead. However, the T-shaped model used in the second half worked towards Uruguay’s advantage as they won 4-2 by the end of the match.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
