In a materials class I am teaching, we show the students a set of videos for mechanical properties, dislocations (with bubble raft model), and strenghening mechanisms. Unfortunately, these videos are really out of date, probably made over twenty years ago. The physics in them remains sound, but the students are often not well impressed due to the poor old VHS quality. I wonder if there exist newly updated versions of similar videos that may be more impressive with the use of more recent technology. I am almost certain it exists somewhere, but don't know how to find it. Your help would be appreciated.
