Also known as a "wobblestone", "celtic stone" or simply "celt", the rattleback is a semi-elipsoidal object that reverses its spin direction. The rattleback seems to violate conservation of angular momentum.

It is somewhat controversial as to what causes this apparent violation of conservation of angular momentum. One theory is that its the result of a non-zero product of inertia.
