conical pendulum?

ys2050

When you hang a pendulum from the ceiling and spin it, (conical pendulum) why does it only spin in one direction??? What's the physics behind the motion and the forces of it that makes it spin in only one direction?

but if you spin it in opposite direction, it won't travel in a circle....;;
