adidas World Cup Jabulani Ball
This week the California Institute of Technology gave new meaning to the concept of “air ball” as aerospace engineers at the prestigious school put the controversial new “Jabulani” football (that’s soccer to most of us Americans) to the test in a wind tunnel. The ball, which was developed by adidas, is currently being used in the World Cup, where players, coaches and fans have blamed it for missed shots. So much for blaming bad play?
According to reports two balls were put into the Lucas Wind Tunnel and exposed to wind speeds of about 10 meters per second, which is actually slower than a typical kicked ball. To determine the movement of air around said balls, a smoke machine was called in. This helped the engineers visualize the air movement. The findings actually matched some complaints from teams in the World Cup. The ball reportedly had some “bizarre trajectories.”
Developed by the adidas Innovation Team (a.i.t.), the ball has been tested as new “match ball” for the 2010 FIFA World Cup in South Africa. This mean tests under the toughest laboratory conditions, but it isn’t clear if this is in fact the first time the ball went into a wind tunnel. At this point it doesn’t look as if the ball will pulled, but with more studies coming dare we say that the wind of change is blowing through.

Nike makes team uniforms from recycled plastic bottles.
The recent trend in sports and fitness clothing is green, sustainability. Nike is part of this trend and especially when it comes to football (that’s soccer to many of you), and the upcoming 2010 World Cup in South Africa. This year Nike is outfitting the Brazil team with home and away kits, plus eight away kits for other Nike-sponsored federations appearing in the games. What’s so sustainable about these kits or outfits you ask? Nike’s fabric suppliers sourced plastic bottles from landfill sites in Japan and Taiwan to produce the jerseys and shorts.
Eight plastic bottles produce one jersey. To turn bottle into soft, breathable fabric bottles the manufacturer melts the plastics down to produce new yarn and then convert that yarn into fabric to construct jerseys. Just because the jerseys are made from plastic doesn’t mean players will drown in their own sweat. Designed to keep players drier, cooler, and more comfortable, the outfit has a handful of features. The Dri-Fit fabric is 15 percent lighter than previous Nike kit fabrications, which also benefits players’ ability to do their stuff out on the field. The coordinating shorts have additional ventilation zones below the waistband and near the base of the spine to keep the outfit breathable.
The outfits have some protection built in as well. Nike Pro Combat, adds protection against light impact and abrasion in the Slider and Impact shorts. The Pro Combat also features a therma Mock that protects a player’s neck against harsh conditions such as sun.
The process saves raw materials and reduces energy consumption by up to 30 percent compared to the manufacture of virgin polyester. For the upcoming season and competition, Nike salvaged roughly 13 million plastic bottles, totaling around 254,000 kg of polyester waste from landfill sites. That’s enough to stretch a distance of 3,000 kilometers if the bottles are laid out end-to-end.
The games take place in South Africa with teams from Brazil, The Netherlands, Portugal, U.S.A., South Korea, Australia, New Zealand, Serbia, and Slovenia. Get your own team kits at nike.com and nikefootball.com.
