  In this account, we describe the crazy-clock phenomenon involving the state I
(low iodide and iodine concentration) to state II (high iodide and iodine
concentration with new iodine phase) transition after a Briggs-Rauscher (BR)
oscillatory process. While the BR crazy-clock phenomenon is known, it is the
first time that crazy-clock behavior is linked and explained with the
symmetry-breaking phenomenon, highlighting the entire process in a novel way.
The presented phenomenon has been thoroughly investigated by running more than
60 experiments, and evaluated by using statistical cluster K-means analysis.
The mixing rate, as well as the magnetic bar shape and dimensions, have a
strong influence on the transition appearance. Although the transition for both
mixing and no-mixing conditions are taking place completely randomly, by using
statistical cluster analysis we obtain different numbers of clusters (showing
the time-domains where the transition is more likely to occur). In the case of
stirring, clusters are more compact and separated, revealed new hidden details
regarding the chemical dynamics of nonlinear processes. The significance of the
presented results is beyond oscillatory reaction kinetics since the described
example belongs to the small class of chemical systems that shows intrinsic
randomness in their response and it might be considered as a real example of a
classical liquid random number generator.
