since the 197 world cup, every world cup will use the football made by adidas as a match. The following are the names of the designated balls for previous matches: 197: Telstar: black and white football. In the 197 World Cup in Mexico, FIFA first appointed adidas to provide official balls for the World Cup. In this World Cup, people broadcast the game on TV for the first time through international communication satellites, so this lucky football was named "Telstar". Tv stars, like all balls at that time, were made entirely of leather. However, TV Star has 32 hand-sewn cushions (12 black pentagons and 2 white pentagons), and its structure and innovative design have written down the history of football. 1974: Telstar,Chile: The latter is all white. In the 1974 World Cup in Germany, FIFA used two kinds of Adidas competition balls-TV Star reappeared with a brand-new gold trademark instead of the previous black trademark; In addition, with the successful experience of TV Star, Adi has also introduced a new all-white ball of Chile. However, regardless of materials and manufacturing technology, the ball used in this World Cup has not improved compared with that used in 197. 1978: Tango In 1978, football design underwent a reform. At that time, the most famous "Tango" design was launched, and Adidas once again brought a "classic football design" work. They made 2 decorative mats containing triads produce 12 equal circles of visual effect, so that every official match ball of the World Cup football match was inspired by this design. Tango is characterized by improved weather resistance and is inspired by the deep passion and elegance of Argentine dance. 1982: The design of Tango Espana tango changed only slightly in 1982. However, "Spanish tango" has an important technological innovation: although the Spanish tango is still made of leather, its revolutionary water sealing seam has broken through the technology at that time. This amazing innovation reduces the water absorption of the ball, thus reducing the weight of the ball. 1986: Azetca: synthetic fiber caused the official competition ball in 1986, which completely changed football and football production technology. The "Azteca" decorated with the architectural style and murals of the Aztec aborigines in Mexico, the host country, is beautiful and exquisite. It is the first ball made of synthetic leather for the World Cup. The use of synthetic materials increases the durability of the ball, and further reduces the absorption of water by the ball, so that the ball can maintain the same performance in hard ground, high altitude and humid environment. 199: Erusco Unico "Etrusco" becomes the designated ball for the World Cup in Italy, which is completely made of synthetic materials and has excellent water resistance. In order to reflect the culture of the host country, Italy, the image of the Etruscan lion head was incorporated into the design of the ball. 1994: Questra In 1994, Adidas launched the first official competition ball featuring high-tech and ultra-high-energy rebound white foam layer. This PE layer makes "Questra" feel softer and easier to handle, and makes kicking more stable, which is not a bad thing for Questra, who is inspired by space exploration, space age technology, high-speed rockets and American "Exploring Planet". 1998: Tricolore: The Tricolore, a new type of composite foam material, is the first colored official competition ball in the history of the World Cup. It is inspired by the colors of the French flag and the gallic rooster. Tricolor ball is characterized by a newly developed "synthetic foam", which further improved the durability and energy rebound of football at that time and was more acute. 22: Fly to fireball # The design of "Fly to fireball" goes beyond the past concept. Its shape design is based on white, and four dynamic darts inlaid with gold and red surround the football surface, which can make players better see the rotation of the football. The dynamic and novel appearance of flying to fireball is inspired by the philosophical thoughts of Korea and Japan: gold symbolizes the passion and vitality given by the host country to the World Cup; The red flame represents the motivation of enthusiasm; The four triangles with the pattern of turbine in the center of the sphere explain the perfect balance of the sphere in industrial language, and also symbolize the achievements made by Korea and Japan in scientific and technological innovation in recent years. Classic goal: June 21, Brazil VS England. In the 49th minute, Brazil got a free kick 3 meters away from the right side of the frontcourt, and Ronaldinho took the penalty. Ronaldinho shot directly from the foot, and the inside of his right foot rubbed out a curveball, which flew over Seaman's head into the upper right corner of the goal. 26: Teamgeist (Team Star): Made of 14 spherical surfaces.
