Does anyone know what the special balls used in previous World Cups are called?

There are pictures in the link

1970 World Cup: Telstar

The name comes from two words: "Television" and "Star" ), this is because this World Cup was the first time that the World Cup was broadcast live to the world via satellite. At the same time, in order to allow users of black and white TVs to see the football more clearly, the designers specially changed the ball that was originally a single color. A black pentagon is inlaid on it. The ball is entirely made of genuine leather, but what is unique is that the surface of the ball is composed of 32 hand-stitched panels (12 black pentagons and 20 white hexagons), giving the ball a rounder and more perfect shape. Although it was mainly for the purpose of aesthetics and convenience for television broadcasts, such a design still had epoch-making significance, at least giving football the nice name "Black and White Elf". To this day, "Telstar" is still a variety of Football prototype.

1974 World Cup: Telstar & Chile

Perhaps because the host country of the World Cup was Germany, their rigid thinking penetrated into the design of football, so this The designated ball for this World Cup is basically the same material and technology as it was four years ago. In this World Cup, two official balls have been used. Except for "Telstar", which is almost the same as the ball four years ago, "Chile" (Chile) took a retro route and returned to a single-color ball. . Because this design is similar to an all-white ball used in the 1962 Chile World Cup, it was named "Chile".

1978 World Cup: Tango

In a country as unrestrained as the host country, Argentina, the traditional dance tango is a perfect combination of excitement and elegance in the country. It is derived from tango. The football that gets its name also strives for breakthroughs in design. In addition to improving the ball's ability to adapt to various climatic conditions, more importantly, 20 "triangular Adidas"-shaped inlays are connected to each other on the surface of the ball to form 12 circles of equal size. Although this was only a non-technological improvement, the surface of subsequent World Cup balls almost maintained this design until 1998.

1982 World Cup Tango Espana

Perhaps because Spain and Argentina are also unrestrained countries, "Tango Espana" (Spanish Tango) only made small improvements in design . The key innovation lies in technology: waterproof and sealed sewing technology is adopted, which greatly reduces the water absorption of the ball and controls the additional increase in ball weight to the maximum extent.

1986 World Cup: Azteca

In 1985, a major earthquake occurred in Mexico. A year later, these descendants of the Aztecs held a World Cup football match on the ruins of the reconstruction. In order to show his admiration for the Mexican people, the designer named the ball "Azteca" (Azteca). The ball's appearance design incorporates the style of Aztec architecture and mural patterns, and it is technically made of synthetic materials for the first time. The use of this synthetic material increases the durability of the ball while further reducing its absorbency. It performs well on hard surfaces, in the air or in wet conditions.

1990 World Cup: Etrusco Unlco

Since Italy is a country with a strong classical charm, the design of football patterns must also pursue classicism. The Italian word "Etrusco Unico" means "the only Etruscan". Etruria is a famous ancient country located in central and western Italy. It was once famous for its exquisite art. Therefore, three Etruscan lion heads are painted on each triangular panel on the surface of the football. In terms of technology, the ball has improved synthetic materials, and for the first time, a black polyurethane foam inner layer has been added to the ball, making the ball completely waterproof and its running speed has been improved again.

1994 World Cup Questra

Although the actual origin of Questra is Catalan, the word also means "Quest" in American English, which means to seek, explore. The United States' unremitting exploration and pursuit of the universe and space inspired designers, so we can see the Milky Way and the vast starry sky on the ball's pattern. For the first time, the ball uses an inner layer of white polyurethane foam with energy recovery properties, making the ball softer to the touch and faster. The designers hope it can fly as high as a rocket off the ground.

1998 World Cup: Tricolors

The word means tricolor in French, which is the French flag composed of blue, white and red, with a ball on the ball. There is the traditional "rooster" symbol that symbolizes the French nation and the French Football Federation. The main innovation of this ball is the use of a new type of composite foam material. The internal structure is a tightly arranged elastic bubble, each bubble is closed and filled with gas. This composite material is more wear-resistant, giving the ball better energy recovery performance, making the ball fly more stable and in a more accurate direction. At the same time, "transparent printing" technology was used for the first time to make the pattern more vivid, not easy to wear and have a longer life.

2002 World Cup: Fevernova

This ball has a nice Chinese name "Fevernova". The name "Fevernova" is divided into two parts: "Fever" in English is It means "fanatical". It means a football craze that will set off around the world every four years. During the month of the World Cup, the whole world will be immersed in the celebration of this football event. The original meaning of "Nova" is a star that shines intensely in a short period of time.

Different from the previous World Cup designated balls, the "Flying Bolide" has achieved a breakthrough in surface design, and has been given a fresh and vibrant image by designers. The dynamic and novel appearance is inspired by the philosophies of South Korea and Japan: the gold symbolizes the passion and vitality given to the 2002 World Cup by the host countries South Korea and Japan; the red flame represents the passionate power; the four turbines in the center of the ball are patterned. The triangle uses industrial language to interpret the perfect balance of the sphere, and also symbolizes the achievements of South Korea and Japan in technological innovation in recent years.

Compared with the breakthroughs on the surface, the progress in the internal structure of "Flying Bolide" is still much greater. After communicating with top players such as Zidane, Beckham, and Barthes, Adidas further improved the World Cup ball based on the "tricolor ball" of the 1998 World Cup. The outer layer of "Flying Bolide" Using a high-tech synthetic foam layer structure, the compositely arranged foam layers enable the "Flying Bolide" to have superior performance beyond any existing football. The improved foam layer is composed of numerous ultra-pressure-resistant and equal-sized micro-airbags. This structure gives the ball body outstanding energy recovery performance and additional force cushioning performance, effectively improving the controllability and accuracy of the football. Spend. At the same time, the three-layer knitted inner patch provides the "Flying Bolide" with good three-dimensional movement characteristics, ensuring that the football can have a more accurate and more predictable flight path every time it travels.

In addition, the "Flying Bolide" has outstanding energy recovery performance and nearly perfect weight and pi. Extensive testing on the mechanical legs of Adidas' football R&D center in Scheinfeld, Germany, has proven that it can fly The Bolide's flight accuracy was unprecedented, and all indicators exceeded all FIFA standards at the time.

2006 World Cup: Teamgeist?

This game ball newly designed by Adidas is called "+Teamgeist" (Teamgeist?), which means winning the World Cup. Important spirit: the power of team. She uses a new special-shaped piece and seamless lamination technology, unprecedentedly reducing the football ball surface pieces to 14 pieces, eliminating irregular concavities and convexities on the surface of the ball to the greatest extent, making the ball present a perfect arc, thus effectively improving the The precision with which football is run.

The "Team Star" (Teamgeist?) is mainly composed of black, white and gold. Black and white are the traditional colors of the host German national football team, while gold represents the World Cup championship trophy.

The roundness and surface smoothness of a football directly determine the stability and accuracy of its operation. The extraordinary thing about "Teamgeist?" is that she revolutionaryly reduces the number of spherical pieces to 14 pieces, while all previous football surfaces were composed of 32 pieces of skin. This innovation has reduced the number of splicing points on the outer surface of the ball from 60 to 24, a reduction of 60%, and the total length of the splicing line has also been reduced from 40.05cm to 33.93cm, a reduction of more than 15%. This block design combined with Adidas' unique seamless lamination technology enables the "Team Star" to exhibit unprecedented performance. Large-scale comparison tests conducted at Loughborough University in the UK and the Adidas laboratory in Scheinfeld, Germany have proven this.

Many stars tried to kick this new World Cup ball before the game. Beckham commented: "'+Team Star' is one of the most beautiful World Cup ball ever, I like it very much!" Raul said: "I think among all Adidas footballs, this '+ Team Star' is the most perfect ball ever. Its design is very unique, and the ball feels very comfortable whether it is passing or shooting."
