The knuckleball, however, is not exclusive to just a soccer ball or a baseball. A study by students at École Polytechnique’s Hydrodynamics Laboratory in France found that almost any ball, be it a tiny plastic bead or a 7 kg steel ball, will move similarly to a knuckleball seen in sports if dropped into a tank of water.

In many sports, players use aerodynamic effects to lure opponents and score. For example in soccer, a free kick may get around the defensive wall thanks to a side spin . Among the different paths , one of the most intriguing paths is probably the zigzagging knuckleball.

Unraveling the Secrets of the Knuckleball | Inside Science

Since Ronaldo undoubtedly knuckles a soccer ball, the process needed another ingredient. That extra ingredient was the drag crisis. "But you need to kick the ball at a velocity close to that of the drag crisis and to do so with no spin to observe the knuckle effect," Cohen said.
