The Jabulani (/ˌdʒæbjʊˈlɑːni/ JAB-yuu-LAH-nee, Zulu: [dʒaɓuˈlaːni]) was a football manufactured by Adidas. It was the official match ball for the 2010 FIFA World Cup.
The ball is made from eight spherically moulded panels and has a textured surface intended to improve aerodynamics. It was consequently developed into the Adidas Tango 12 series of footballs. The Jabulani had a mixed reception during the World Cup due to its unusual flight pattern. The NASA Ames Research Center studied its performance and compared it to the +Teamgeist Berlin (used in the 2006 World Cup) and found it had a noticeable "knuckleball" effect.
