Bought this as a birthday gift for a 10-yr old boy who loves soccer. The ball is made of a durable rubber material, but it is official weight and size for those who are wondering. The rubber exterior gives the ball more bounce than a typical "official" soccer ball, but IMO it makes the ball more fun to kick around as well as more durable. There are 2 LED lights inside the ball which illuminate when the ball is kicked or tossed onto the ground. LED's shut off automatically after about a minute of inactivity which helps conserve the batteries. No more calling off the soccer game when the sun sets, this ball makes it possible to play in pitch dark conditions and is a blast to kick around. Fun for all ages, kids as well as adults. Great buy, 5 stars.
Footballs have gone through a dramatic change over time. During medieval times balls were normally made from an outer shell of leather filled with cork shavings. Another method of creating a ball was using animal bladders for the inside of the ball making it inflatable. However, these two styles of creating footballs made it easy for the ball to puncture and were inadequate for kicking. It was not until the 19th century that footballs developed into what a football looks like today.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
