Abstract
A bowling pin has a pin body with a head and a magnet, at least partially enclosed in a plastic envelope, positioned in the head for manipulating the bowling pin. The plastic envelope and the head are fused to one another by rotating the plastic envelope within a cutout of the head so that the contact surfaces are heated for softening and fusing the material.
