This year, the ball shouldn’t have that kind of impact on which team wins the World Cup. In wind tunnel tests, Goff found that Telstar 18 has a very similar aerodynamic profile to the 2014 Brazuca ball, which flew without the wobbles of the Jabulani. The Jabulani was the first ball to have six seams and despite having a roughened surface, it was too smooth, says Goff. When the Brazuca was released, it had 68 percent more seams than the Jabulani to help change the airflow around the ball. The Telstar 18 is even more improved. Instead of transitioning to laminar flow in the middle of free kicks, Goff found that the Telstar 18 goes through its drag crisis at a lower speed of 38 miles an hour.
The history of soccer balls date back to ancient times. From a couple centuries BC to about 200 AD, the Chinese used balls made from animal skins in a game called 'tsu chu', in which players had to pass them through a net stretched between two poles. The ancient Greeks, Romans, and even the Egyptians are recorded to have enjoyed a similar game that involved kicking a makeshift ball.
These are used in international level matches and top league matches like UEFA Champions League, Italian Serie A, English Premier League, Spanish La Liga, Bundesliga, Major League Soccer. Not only these but also all the tournaments approved by FIFA. So you can easily understand that these are the highest quality balls with the highest level of air retention, shape, water absorption, trajectory, curve, and performance. Otherwise, FIFA would not have approved these balls.
When a tournament is held (like the FIFA World Cup), the sponsor of the event will design a brand new ball. These are official match balls – they’re used by professionals during real matches. They are designed to the highest possible build quality, have textured surfaces to improve stability in flight, and feature thermally-bonded panels for durability.
This ball has a TPU cover that we wouldn’t describe as “highly durable” for rough play. Although it handles indoor turf, it won’t handle concrete, gravel, or court-based play like you have with futsal. This ball prefers to have a natural or artificial grass surface and that is about it. If you happen to impact a tree, run the ball on concrete, or have it bounce on a gravel driveway, the outer cover does tend to get scratched up pretty rapidly. The butyl bladder is of a higher quality than other balls at this price point, allowing the ball to hold its inflation pressure with an impressive amount of consistency.
Soccer — or football as it's known around the world — is arguably the most loved sport on Earth. Although Americans still aren't as enamored of the sport as the rest of the world is, teams around the country are stealing hearts and minds, and Americans are getting into the game. For years, soccer has been a sport played by kids, college students, and ex-pats, but it's now being cheered in stadiums and watched on national TV. https://www.youtube.com/watch?v=DGp37du0xbQ
