Abstract
Dynamic, spinning, twisting string toys referred to as "humdingers" are disclosed. The toys include at least one highly elastic gel body having at least two holes extending through the body along a selected axis of rotation. The holes are treaded with a string(s) which are twisted and untwisted alternatively by the pulling and releasing action of the strings. The holes are provided with means to resist the shearing forces of the twisting strings. The dynamic effect of the extreme high centrifugal and shearing forces generated during play causes the gel bodies to change shape during spinning. Soft gels or low strength materials can also be substituted in place of the highly elastic gel body provide the body reinforced with shear resistant means to prevent cutting by the twisting and untwisting actions of the string(s).
