and perpendicular to the faces of the puck, with sufficient
freedom of movement to permit the weight to permit the central
axis of the weight to become angularly offset from normal to
the faces and to permit the weight to simultaneously contact
both of the faces so that the puck will more readily topple
when rolling on it side.
