The Dynaflex Power Ball by Liberty Mountain is the ultimate in engineering design work featuring the same user friendly features and incorporating an on-board generator. By activating the gyro, a dynamism (motion) is created which will activate the LED lights located in the interior of the gyro. The faster the unit runs, the brighter the lights will be until the whole hand is engulfed in a bright glow. The Powerball also features a balanced rotor and removable top cap, which will allow insertion of the optional digital speed meter.
