Abstract
A mold producing one or more globe-shaped bells, each of which is cast as a one-piece shell enclosing a tumbling ball-bearing or jinglet. Production of the one-piece shell is made possible by pouring molten metal over a spherical core, supported by small 'feet' inside the globe-like cavity of the mold. When the shell is removed from the mold, the core, in which the ball-bearing or jinglet is embedded, can easily be disintegrated or broken down into particles which fall out holes in the shell's surface.
