Lab course for Ching Cheng senior high school (精誠高中)

We had visitors from Ching Cheng senior high school (精誠高中). We gave lectures and observed their experiments of electrochemical polymerization of aniline and its electrochromism. Hope they enjoyed our lab and the lab course. Kaijen, Shiaochi, Kuolung, Hsinyu, thanks a lot for your help!
