Thanks! in order to do that i would need to apply exactly the same torque in exactly the same conditions since the difference one way or the other will be minimal. I was wondrering if there is a mathematical way to find out.

Hi I was playing with my daughter's fidget and was wondering how should I hold it in order for it to spin the longest amount of time. Verticlly, horizontally or at an angle in between? Any suggestions?
