I was curious what the margin of error for this was (I'm conjecturing the sum of widths of the fingers touching the stick), so I tried this out, but with a pencil instead of a stick.
I was consistently getting just off-center, so I was thinking maybe the 'surprise' wasn't consistent, until I realized the end of the pencil (metal + eraser) is probably denser than the wood and shifts the center of mass to exactly where my fingers ended up. :)
