Typical experimental time trace. Region 1: the stirrer is off, corresponding to an average intensity of 80%. Region 2: At t = 20 s, honey is poured and some fluctuations are recorded, but most honey falls to the bottom. At this point, there is also an influence of diffusion process, noticed at t = 35 s. Region 3: the stirrer is turned on causing the sudden drop in light intensity. Region 4: the pattern of an exponential decay is noticed in a short period of time at t = 50 s, providing information about the fluid’s homogeneity through light intensity measurements. In t = 80 s, the stirrer is turned off and there is no longer data acquisition.
