Still fidgeting? Just put a drop of oil on it and it will not work as well (darn!), keep away from kids that will eat anything (kid that ate the bearing, why?)as a screwdriver or knife will pop the plastic off and the bearing will push out, I tried it and it does easily. Give them the yo-yo, a slinky, hula-hoop or Mr & Mrs. Potato Head and let'em go have fun, I know we did and never ate the parts, put an eye out, flushed down the toilet, etc. I as far as I know am a normal, adjusted, function adult human with the normal attention span and... what, oh yeah, and can function in society without a spinning finger top to keep me under control. Give me the tennis ball cannon, potato cannon and bb gun, all sound like fun and were when I was a kid and no one died or lost body parts.
