Belousov-Zhabotinsky reaction
That is indeed a fascinating reaction!  The following is a part answer, providing links to some resources that may be of use.

The following resources may be of assistance:

The Belousov-Zhabotinsky page from the Kansas Academy for Mathematics and Science Education provides a bit about the background, chemical processes and most relevant to your request, an experimental procedure.

Mary Newton of the Georgia Regent University has provided a reasonably detailed procedure on the webpage Procedure for B-Z reaction.

Slightly different, is the information provided in the Belousov-Zhabotinsky Reaction (Leigh) page from the Flathead Valley Community College takes a different approach, with a focus on the mathematical derivations relevant to the experiment.
