Adidas attempted to create a ball that was rounder than ever by decreasing the number of panels again, from 14 on the Teamgeist to just eight on the Jabulani. It was viewed as so unpredictable , though, that goalkeepers revolted. Adidas countered by claiming they had been testing the ball for six months, and pointed to praise by Adidas-sponsored players such as Frank Lampard and Michael Ballack. In the end, it took a NASA study to get to the bottom of the issue. They discovered that the Jabulani started to’knuckle’ (move in the air) at a higher speed than previous balls because of its smoother surface with fewer seams. That sounds like a good thing in theory, but the problem was that shots such as direct free-kicks tended to travel at that higher speed – making the effect more noticeable in practice. When a relatively smooth ball with seams flies through the air without much spin, the air close to the surface is affected by the seams, producing an asymmetric flow. This asymmetry creates side forces that can suddenly push the ball in one direction and cause volatile swerves and swoops and this effect is referred to as knuckling.
