  The blue bottle experiment was first introduced to the chemical education
literature as a simple demonstration on kinetics. Its original formulation
contains only glucose, NaOH and small amount of methylene blue. The solution
turns blue when shaken and fades to colorless upon standing. This
bluing/de-bluing cycle may be repeated and may be compared to blood colors in
animal's respiratory cycle. Inspired by the blue bottle experiment, the
colorful chemical bottle experiment kit was commercially developed in 2006. The
kit is a versatile pedagogical tool, not only for physical chemistry but also
for analytical, biological and organic chemistry. It also helps teaching
concepts in scientific method and laboratory safety. This manuscript contains
four parts, brief review on literature relating to the blue bottle experiment,
description of the colorful chemical bottle experiment kit, pedagogical
discussion of the experiments and preliminary evaluation from students.
