"Better yet- just take your scissors and cut out a number 7- now hold the seven down with your pencil lead in the middle of the top line and when you rotate it- see if the bottom of the 7 - goes lower- down further - even when the "left shoulder" is moving "up" past the point of the top line being parallel to the ground. In either the 7 or the perpendicular one- low point ends up opposite the left shoulder."

Mike O,

I cut out the 7, and by gum, it works!
