What? You're already bored with your plain old fidget spinner? This gravity-driven fidget spinner should provide you with minutes more of spinning entertainment!
To get it going, you flip the spinner so that the bearing is at the bottom of the twisty shaft. Then pinch on the bearing holder so that it grabs the nut in the inner bearing race. Gravity will pull the mass downward, giving it a good spin at the same time. Now the tricky part: just before it reaches the bottom, release the pressure on the bearing holder and the bearing can now spin freely. Flip it over and do it again and again (and again)!
