WHAT IS A POWERBALL?
Introduction
The Original Powerball is the ideal training device for sports like tennis, golf, basket-ball, table tennis, badminton, bowling, rowing, rock-climbing etc.
Powerball training improves your performance in these sports considerably and is great fun at the same time. You exercise muscles in your arms, your wrists, the grip of your fingers and your coordination.
Moreover, Powerball helps to prevent tennis elbow, Carpal Tunnel Syndrome and Repetitive Strain Injury (RSI Syndrome). It can ease pain in muscles and shoulders after working long hours on the computer.
The principle of the Original Powerball is the gyroscope.
A gyroscope is a solid object that is designed to spin around a central axis. The ends of the axle rest on bearings in a steel ring, or gimbal. Start the top spinning and as long as it continues to spin rapidly, the top will remain balanced on its pointed end.
Actually you can compare a Powerball in motion to a glass of whisky-on-the-rocks.
You hold it from the top and make the ice-cubes move in a circle.
More important, the direction of the top's spin axis will resist any attempt to change the direction of the axis about which the rotor turns. This basic property results from the top's strong Angular Momentum. The rigidity in space of a gyroscope is a consequence of Newton's first law of motion which states that a body at rest tends to continue in its state of rest or uniform motion unless subject to outside forces. Thus, the wheel of a gyroscope, when started spinning, tends to continue to rotate in the same plane about the same axis in space...
Precession - When a force (your hand) is applied to a gyroscope it tends to change the direction of the axis of rotation, the axis will move in a direction at right angles to the direction in which the force is applied.
Inside the Powerball there is a rotor of about 200 gram which is being accelerated by a round movement of the hand. The rotor can perform as many as 16.000 rpm (revolutions per minute) and thus generate a force of about 80 times the weight of the rotor, as much as 16 kilograms!!
Quality features of the Original Powerball.
[1] The rotation is balanced by computer and thus is absolutely precise
[2] The axle is made of steel and cannot break
[3] The models with generator (PB 188 Lightning and PB-188 Max) feature a fascinating light-effect. 6 Power LED´s. No batteries necessary.
[4] With the grip band around the Powerball you hold it firmly in your hand and it does not slip away
[5] The housing is made of durable plastic
[6] The rotor can make as much as 14,000 rpm (revolutions per minute) and generates a force of up to 16 kg.
[7] The original Powerball is available with digital counter or the counter can be fixed onto the Powerball later on.
How to start the Powerball
With the starter string:
Put the point of the string into the little hole in the rotor and wind it up.
To start now you hold the Powerball firmly in one hand and pull the string with power.
Now you start moving your hand in a circle and try to build up the speed of the rotor.
To start with your hand:
Hold the Powerball in one hand and accelerate the rotor with the thumb or palm of your other hand.
The initial speed of the rotor has to be just right and you can just go on with a round movement of your wrist.
Now you start moving your hand in a circle and try to build up the speed of the rotor.
