This is a simple experimental set up that allows students to visualize the processes involved in spectrophotometric measurements. As a bonus, excellent results are obtained. Simple materials and a smartphone are used to measure concentrations of Red Dye #40 in Strawberry PowerAde Zero. The experimental design and data analysis mimics several basic features of involved in absorption spectrophotometry and Beer's Law analysis.
