Brazuca: Even NASA tested the ball of Brasil 2014 world cup.

World cup just began and all the world turn around the Brazuca, the official of the 2014 FIFA world cup. The ball is manufactured in Pakistan by the sport label ADIDAS.

Besides it 69 cm circumference and it 437 grams, what is special about Brazuca compared to other balls?

Unique aerodynamic
There is some controversy about the effect of wind on the game. Especially the Jabulani ball (2010 world cup) was severely criticized about its aerodynamics and its erratic movement. ADIDAS states that aerodynamic problems will not be present in the Brazuca due to its six identical locking patches that makes it the most spheric ball. The previous Jabulani had eight non-identical patches and the classic balls have 32 hexagonal patches.

Even scientists from NASA had tested the aerodynamics of the Brazuca. NASA tested the Brazuca through a wind tunnel and analyzed its aerodynamics at different speeds.

The roughness of the material and the 6 thermally bonded locking patches increase the seam length; such characteristic along with the roughness of the micro-textured surface improved the aerodynamics and eliminates the erratic movement of Jubulani. Its will produce faster speed and maintain the shape and weight of the ball.

Why Brazuca?
The name Brazuca was selected by a public vote conducted on line in 2012. It is an informal description of the Brazilian way of life. The other names considered in the vote were Bossa Nova (A very famous genre of Brazilian music) and Carnavalesca (due to the fame of the Brazilian carnival).

The colours and ribbon design of the ball panels symbolize the traditional multi-coloured wish bracelets (fita do Senhor do Bonfirm da Bahia) worn in the country, in addition to reflecting the vibrancy and fun associated with football in Brazil.
