As far as I knew a powerball was omething you put into the washing machine with your clothes.
What do yuo do with a powerball exactlty?
After reading your post, I looked it up, and at first I thought that you were some sort of gambler, since the first results I got for "powerball" involved the lottery in some way. 11000 rpm just doesn't flow with the lottery, though, so I looked further, and apparantly a powerball is a "grip strengthening device." Now, how it works, I don't know. All I do know is that you have to do something with your wrist, but my knowledge ends there. If you want to say more about this powerball, and inform the uninformed, please do. I'm interested as to whether this ball is any fun.
My brother in law suffers from Carpal Tunnel Sybdrome. Could this ball make a diffwerence to him at all?
There is a ton of them for sale on ebay, some are too expensive but others are quite reasonable IF they would be of some use.
power balls? really can give you power?
