A self-contained precision crafted gyroscope, the Powerball has been carefully manufactured using high-quality materials and finely balanced using state of the art computer technology to ensure zero vibration up to speeds in excess of 15,000 rpm. It is about the size of a tennis ball and can generate the equivalent of over 40lbs of force. "
