Abstract:

A game and sport device which can be used to repeatably mold and accurately throw snowballs as launched missiles. It comprises a hollow plastic shaft having a cup used for molding and holding a snowball at one or both ends. Snowballs are held in place by snow compacted into a series of 360. degree. grooves inside each end cup. They are launched into flight at about the zenith of the throwing motion when the force of the throw exceeds the shear force of the snow where it is compacted into the grooves. The widest cup diameter occurs at the cup mouth and the snowballs are discharged from the device as a single mass of material. Two cups each having a different groove pattern, sizes or the like can be provided at opposite ends of the device to allow opportunity for cup selection to compensate for various snow conditions.
