Try these other ways. Hold it between your thumb and first finger and flick it with your third, fourth or fifth finger. It can be spun on a table. Also, pinch one of the arm bearings between your thumb and middle finger, and with a wrist motion you can spin it as long as you want on the arm bearing. No finger flicking required.
