Videos – Dynamic Equilibrium and Critical Opalescence

We made two videos this week to help illustrate some of our demos. We welcome any feedback you may have!

Second, we performed and filmed Critical Opalescence.  This one is tricky to do in class, as the temperature and timing are finicky. The first part of the video (heating stage) is sped up 1000%, and the second part (cooling stage) is sped up 2000%. There is no sound
