Today I was introduced to a very cool device designed to relax your arm muscles, being a round shape that contains a yo-yo shaped ball inside that you can spin up, then continually wiggle your arm and the device will vibrate thanks to the centrifugal force. It does not use any batteries.
It's very cool and I spent about half an hour with that thing before I had to leave and return the device to its owner.
The owner told me that she bought it at Fry's Electronics for $18 and I can probably buy it at Academy.
I remember seeing the name on it being "DuraFlex" or something like that, but I'm not sure about the "Dura" part. It's <something>Flex.
Does anyone know what that thing is called? I really want it, but neither store (neither Fry's nor Academy) offers an online product listing. Google also yielded no helpful results, probably because "DuraFlex" is not right.
Any help is appreciated.
