Abstract This paper designed micro chemical experiments with "drops" as a unit of measurement, together with visualization techniques of phenomena and processes, to observe the unnoticeable details in the droplets. And then took the most typical 3 phenomena (generating bubbles, generating solids, color changes) in chemical reaction as examples to show the visualization effect. This experiment had the characteristics of visualization, miniaturization, family orientation, and interesting, and the required experimental equipment could be replaced with daily necessities, so it was suitable for a home experiment.
