If you want to train to the pros and be the worlds greatest soccer player of all time like me you have to practice and learn all different skills. But their is an easier way to practice and it is with this ball Adidas made called the SmartBall. With built in technology/sensors the SmartBall tells you how to curve ,how fast your kick is, and your level of skill you have based on the kick. If you mess up, the ball will tell you with an app to kick the ball at a certain part in your body. For it to work you need to charge it.
It relates to engineering because the entire ball has sensors and tech inside it to make you a better shooter, passer and to have great free kicks.
