I have about 30 soccer balls- price listed is per ball. I have more than the 12 pictured- some doubles of the champions league balls, two of the unwrapped Brine ball, 5 or so futsal balls. Some are worth more than 25, some less. Just make me a good off and tell me which ball you want! Keep in mind when you offer that I am paying most of the shipping already. Balls will ship deflated. I will reconfirm that all hold air and make sure they are cleaned off before shipping. There is only one ball in the lot that has a gouge/ panel issue. All aside are in good playable shape.
When any object goes through the air, a thin cushion of air wraps around it that stays relatively still. This boundary layer is why you get dust trapped on your ceiling fan. At slower speeds, the air around a soccer ball moves smoothly over the surface and separates off the sides of the ball at its widest points. Imagine a ball moving from right to left across a clock, Goff explains, so traveling from the 3 to the 9. With laminar flow, the air flows over the surface and then flows off at the 12 and 6, which creates more drag in the air. Drag slows the ball down faster. At higher speeds, the air moves turbulently across the ball’s surface and peels off at the 2 and 4. The wind effectively wraps around the back. This turbulent flow has less drag, which means the ball keeps moving at high speed for longer.
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.
Changes in temperature will also affect the inflation level of the soccer ball. Extreme heat or extreme cold will alter the shape of the bladder and this will affect the integrity of the soccer ball. Although it doesn’t seem like you could reach an extreme temperature that could do this to a soccer ball, just leaving a ball in your trunk or the back of a van on a hot Summer’s day will do it.

The secret to the authentic movements on a rebound with this ball is the inclusion of an SBR foam layer underneath the PU cover. This allows the power of a pass or shot to be transferred with more accuracy. It keeps the ball somewhat soft to the touch, but creates a realistic movement which allows players to develop an ability to start reading the game with accuracy without the need to purchase an expensive premium match soccer ball. It comes in all of the standard sizes and offers 4 unique design options, allowing players of any age or ability to begin working on their soccer skills.
