Powerball
The world's fastest non-motorised instrument in the palm of your hand!
Powerball is a revolutionary gyroscope, once started it slowly comes alive with gyroscopic force - a pleasant resistance to your movement, which is transmitted directly into your wrist and arms and which can even provide soothing, non impact rehabilitation at lower speeds. But who cares about lower speeds when you can go faster and faster until you have it up to an unbelievable 15,000rpm; then it 's exerting almost 40lbs of pressure on you and is travelling at nearly 250 revolutions per second!
