What techniques are included in the football used in the World Cup?

The ball for the World Cup in South Africa will be released at this weekend's World Cup draw ceremony, but the British "Sun" exposed the true face of the ball in advance yesterday: its name is "Universal Celebration", which comes from Zulu language in South Africa, meaning "to celebrate", and the overall design is full of strong South African tribal style. ?

The official ball for the World Cup in South Africa was designed and produced by Adidas, the main sponsor of FIFA. It is said that this is the "roundest football" in history. It adopts high-precision technology such as "tight suction groove pressing line technology" to make the ball have stable flight trajectory and perfect stability in any weather conditions. This ball uses the most different colors of 1 1 in history, representing 1 1 players of the team. The official price of this ball for the World Cup in South Africa is about 100 Euro.

Waka waka has also released a song titled "Flag Flying", which was sung by Somali Canadian singer Conan. The lyrics praise freedom, equality and love, and have a strong African flavor.
