Using hand rotation, spin the internal gyro and challenge yourself and others to achieve the highest revolution per minute. Pull the red cord to spin the gyroscope inside the ball. Rotating the ball in your hands increases the rotation of the gyroscope. The digital counter measures the speed of the gyroscope and displays the number of revolutions per minute (RPM). Good training for golfers and racket sport enthusiasts, but mostly this is for gadget lovers.
