From time to time, you may find it of some benefit to be able to open your Powerball up. Whether to give him a quick clean out or simply to replace a worn component inside.

The outer sphere shell is comprised of two separate halves, both of which have been precision manufactured to allow them snap perfectly together tightly without the need for glue.

The fastest way of opening these halves once they have been joined is to squeeze them at the point at which they meet. Below are the steps:

A gyroscopic exercise tool is a device used to exercise the wrist as part of physical therapy or in order to build hand and finger strength. It can also be used as a clever demonstration of some aspects of rotational dynamics. The device consists of a tennis ball-sized plastic or metal shell around a free-spinning mass, which can be started with a short rip string or by a snap of the thumb. Once the gyroscope inside is going fast enough, a person holding the device can accelerate the spinning mass to high revolution rates by moving the wrist in a circular motion.
