All those equations you learn in physics class describe how aspects of the real world work, right? Which is why physics class lends itself so well to live demonstrations. (Biology, not so much. Living things have this annoying tendency toward autonomous behavior. In short, they don't always do what you want to them to.) The University of Chicago has posted some of the most dramatic demonstrations that Heinrich Jaeger and Sidney Nagel use to teach their introductory physics class.
In this clip, they show off the effects of temperature on the volume of a gas. Bring on the liquid nitrogen!
Thanks to the University of Chicago Magazine for the pointer. (Notice, by the way, that Jaeger and Nagel always wear their safety goggles.)
