2006 Teamgeist Adidas The Teamgeist is a 14-panel ball. Each match at the World Cup finals had its own individual ball, printed with the date of the match, the stadium and the team names. A special variant, the gold-coloured Teamgeist Berlin, was used in the final match. As in 2003, the ball used for the 2007 Women's World Cup was identical in performance to the ball used in the previous year's World Cup, but with a different visual design. 
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.
When any object goes through the air, a thin cushion of air wraps around it that stays relatively still. This boundary layer is why you get dust trapped on your ceiling fan. At slower speeds, the air around a soccer ball moves smoothly over the surface and separates off the sides of the ball at its widest points. Imagine a ball moving from right to left across a clock, Goff explains, so traveling from the 3 to the 9. With laminar flow, the air flows over the surface and then flows off at the 12 and 6, which creates more drag in the air. Drag slows the ball down faster. At higher speeds, the air moves turbulently across the ball’s surface and peels off at the 2 and 4. The wind effectively wraps around the back. This turbulent flow has less drag, which means the ball keeps moving at high speed for longer.
Overall nice soccer ball for a toddler. The colors are bright and the ball is pretty soft. It came in a small box and was easy to blow up. The air pump came with it as well. I blew up the ball as soon as I got it and let the ball sit for a couple of days then filled it again once or twice and I think that helped the ball get back to its round shape as over reviews mentioned theirs being slightly off shape.
Match balls are constructed specifically for competition and the sport's high-level training. These balls feature higher quality materials and must conform to regulation standards of your league. Training and recreational soccer balls are designed to handle extended use on a variety of playing surfaces, often featuring a PVA casing for enhanced durability.
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 soccer balls are exact replicas of the finale game balls, right on down to the specific design details that can be found on the ball. If you’re looking for a durable, reliable ball that can help players replicated the feeling of playing the game at home, then the Top Training Series by Adidas is one of the best options to consider today. Each ball is guaranteed to pass FIFA tests for weight, circumference, rebound, and water absorption. It is the closest you can get in the entry-level categories for a soccer ball to the match ball experience. https://www.youtube.com/watch?v=3OKagE2ZIRA
