If you’ve been watching the 2010 World Cup you’ve probably caught wind of a few controversies, most notable of which is the telecasting grief caused by South Africa’s now infamous cultural instrument, the vuvuzela. But have you heard about the Jabulani hullabaloo?
The Jabulani, for those of you who aren’t familiar with the term, is the name of Adidas’ new World Cup football (or ‘soccer ball’), and it’s been causing quite a stir on the pitch. Between heinous shots ‘on net’ that soar into the stands and awkwardly bouncing balls that fumble their way past goalkeepers with the promise of YouTube replays that will haunt them forever, the players have had a lot to say about the Jabulani. Italian goalkeeper, Gianluigi Buffon, has expressed his sadness that the world’s most popular championship “will be played with such an inadequate ball”. Echoing those sentiments is Luís Fabiano, the Brazillian striker quoted as saying “obviously the guy who designed this ball never played football”. But in sports equipment engineering labs around the world, scientists are celebrating the most spherical and aerodynamically stable ball ever created.
Did you know? Jabulani means "rejoice" in Zulu, one of South Africa’s 11 official languages. The World Cup final match will be played with a gold-coloured variant called the Jo’bulani; a name inspired by Johannesburg (sometimes nicknamed “Jo’burg”).
The Jabulani is an eight-panelled, thermally-bonded (as opposed to stitched) polymer-based ball composed of ethylene-vinyl acetate (EVA) and thermoplastic polyurethane (TPU). EVA is a soft and flexible plastic that is durable, waterproof and resistant to impact stress. EVA is commonly used in sports equipment such as ski boots, surfboard traction pads and fishing rods, but thanks to its inert chemical nature it is also used in the biomedical engineering of implants and prosthetics. TPU, like EVA, is a durable plastic that provides the ball with more bounce. Unlike past World Cup footballs, the Jabulani is covered with shallow grooves that reportedly enhance the aerodynamics of the ball, allowing players better control over how it flies.
Ultimately, this controversy over ball quality is nothing new to FIFA and the World Cup. With every championship comes the introduction of a new football and as the tournament progresses and players adjust, criticism will subside. In the meantime, it’s nice to know that behind the scenes scientists are working to improve the world’s favourite sport. Now if only they could design microphones that mute vuvuzelas...
Did you know? Adidas has designed every World Cup soccer ball since 1970 which also marked the first time the World Cup used the "Buckminster" ball design (the ball made with black and white pentagonal/hexagonal panels) because that year’s World Cup, played in Mexico, was the first to be broadcast live and a black and white ball showed up more clearly on black and white televisions.
