it was hard letting go of this gyroscope. I found myself still missing it a year after of getting my hands on a review unit. It's one of my favourite toys and I reccomend it to anyone with opposable thumbs.
There's a considerable sense of wonder about this, you can generate enough electricity using your hand to light an LED that is powerful enough to illuminate a small radius around you, the Powerball is a well calibrated gyroscope - you need to hand-start it up to about 1500 RPM using a charger cord.. crunch your wrists in a circular motion, and you can make this thing go faster and faster. At high speeds, it's weight is quickly multipled by many factors, and the 250 gram ball can exert the force of a dumbell.. Here's how the company describes it: You set this rotor in motion using a cord or your finger and build its speed by subtle rotation of the wrist. It contains no motor or no batteries. The faster you spin the inner rotor the more inertia it generates and the more resistance it subsequently inflicts upon the fingers, hands, wrists, arms and shoulders.
There are many options and versions, including an all-aluminium one that weighs 350 grams. There's one which makes a lot of noise, and one that has an LED light, another one has a RPM readout meter. I got the one with the LED light as it would function like a torch while I'm out camping. I don't know if I'm qualified to comment on its therapeutic benefits, I feel a general improvement in forearm strength and touch typing after going for a few rounds with this.
