Law of Diminishing Marginal Returns part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
An ILD to help demonstrate the Law of Diminishing Marginal Returns using an experiment.

Pressure Melting of Ice: While-U-Wait part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
In this demonstration, students get to witness pressure melting and regelation first-hand. A weight is suspended via a thin wire over an ice cube. Over the course of the course of the demonstration, the wire passess through the ice, leaving undamaged ice in its wake.
