I think I sent you the string ones??? I need to send you a real one, not that you cant make a pendulum out of anything, but
You ask "show me yes" then "show me no" then "show me I don't want to answer" then "show me I don't know" and it should swing the direction for the answers, back and forth, sideways, counter clockwise, and clockwise. When it wants to stop it will.
And form time to time ill ask mine again to make sure it hasn't changed it's swing.
I have one I always carry, and the one I depend on, seems my collection does not always want to answer.
So try that
