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. 
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.
This 12-oz. ball works for players between 8 and 12 years old and has a circumference of 26 inches, larger than a size 3 and smaller than the size 5. This age group tends to play on a field of about 30 to 50 yards, writes Deborah W. Crisfield in "The Everything Kids' Soccer Book," with a goal size of around 6 feet high and 18 feet long. Again, the scale for the U12s falls between that of the U8s and that of the older age brackets for the No. 4 ball and the game as a whole. Some leagues may limit the No. 4 ball to U10s instead of U12s, so check league rules before making a purchase.
The ultimate determination is how a soccer ball feels and performs for you on contact. A good soccer ball will not only be tough enough to hold up to your fast and furious play, it will feature a soft casing for comfortable heading, and durable stitching (if stitched). It should handle well, and have good response. Most good soccer game balls feature a poly-urethane (PU) casing. Most leagues prefer 32-panel designs for its performance value. Also check for a warranty. Your new soccer ball should come with a manufacturer's warranty against defects and damage caused by normal play.
Every four years there’s a new ball for the World Cup—and every four years players are unhappy with it. Maybe it’s too light and has too much lift, like the 2002 Fevernova. Or maybe it wobbles unexpectedly in the air, making it harder for goalies to predict its motion, like the 2006 Teamgist. Or maybe the ball suddenly changes speed, dropping out of the air and causing accidental handballs, like the 2010 Jabulani.
Using a wind tunnel, Goff has researched the flight properties of the Telstar 18, drawing its drag curve to discover where the ball might dip and swerve in the air, similar to the knuckleball free kicks favored by Cristiano Ronaldo “Even if aerodynamically the Telstar 18 isn’t that different from the Brazuca, it’s still going to wobble a little bit differently because the panel shapes are different,” Goff says.
This ball is available in several sizes that are perfect to suit a variety of ages and soccer league requirements. A size 3 ball is the common size recommended for children under the age of 8 and recommended by most junior leagues. Playing soccer can help your child develop their gross-motor skills as well as balance and coordination. Soccer is also a teamwork-heavy game that requires everyone to work together in order to win. This can encourage your child to build friendships and improves socialization skills.
What sets each soccer ball apart from another is the quality of the materials that are used in its construction. The lining, bladder, cover, and the quality of the overall craftsmanship will all influence the final cost of the soccer ball you’re looking at. Higher quality balls are usually bonded together to provide a superior shape retention experience and offer a truer flight.
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.

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.
A radically new configuration reduced the amount of panel touch points forming a smooth and perfectly round exterior that improved accuracy and control. Prior to the Teamgeist, the surface of World Cup match balls had notable differences depending on where a player would strike the ball due to seams, ridges and other imperfections where panels come together. The revolutionary propeller design of the Teamgeist minimized corners and created a smoother surface for improved play. The ball was designed with traditional colors of the German flag and was accentuated with the golden color of the World Cup trophy.
Built for durability, recreation balls are made of soft synthetic materials for play on nearly any field. Typically, these balls are slightly heavier for beginner’s slower play, yet, competitors of all skill levels use these balls for practice and recreation on hard turf fields due to their resilience. Machine-stitching is the most stand-out visual difference between match balls and training balls and it offers a consistent touch for any player.
