Abstract

The celt or rattleback, sometimes called wobblestone, has a semi-spheroidal rigid body with asymmetric mass distribution. When it is rotated on a horizontal smooth surface such as a table, it “rattles” and eventually rotates in the opposite direction. It is a toy that makes a strange motion that seems to be breaking a law of conservation of angular momentum. In this paper, we look back on the history of research on the spin reversal mechanism of the celt and consider the chirality causing spin reversal. Finally, a spin reversal phenomenon of the “chiral balancing toy” has been introduced as a novel open question.
