marc kastner presents an elaborate and impressive selection of some of the more popular physics demonstrations in the lecture demo group's repertoire to the dept staff during a get together a few years back, when he was still serving as our very warmly regarded physics dept chair :)

i taped this w/ my portable studio handheld just for fun, i'm glad i did

the demos (and not an insignificant amount of my handiwork :), marc as presenter, and course 8 all come across brilliantly i think
