In 2010, the infamous Jabulani balls for the World Cup in South Africa transitioned from turbulent to laminar flow between 50 and 45 miles per hour, right at the speed for corner and free kicks. The transition between these different types of flow causes even more drag on the ball, which caused the Jabulani to wobble in the air and drop in ways that players weren’t expecting.
These soccer balls are exact replicas of the finale game balls, right on down to the specific design details that can be found on the ball. If you’re looking for a durable, reliable ball that can help players replicated the feeling of playing the game at home, then the Top Training Series by Adidas is one of the best options to consider today. Each ball is guaranteed to pass FIFA tests for weight, circumference, rebound, and water absorption. It is the closest you can get in the entry-level categories for a soccer ball to the match ball experience. https://www.youtube.com/watch?v=3OKagE2ZIRA
