Thoroughly TestedSo, with the World Cup (Go Oranje!) heading toward the finals, this seems newsworthy:
Aerodynamic experts from NASA’s Ames Investigation Centre stated the Jabulani becomes unpredictable at speeds above 44mph.
They also blamed the ball’s light weight of just 440 grams for the poor flight and lack of consistency, known as the ‘knuckle effect’.
NASA also believe the altitude could have increased the unpredictable nature of the ball, as most stadiums in South Africa are 1,000 metres above sea level.
