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.
