Transient Heat Conduction
written by Jed Brody
Using only a laser, a stopwatch, ice water, and any transparent liquid or solid, test the equation that Fourier series were invented to solve!  The laser beam's deflection increases and then mysteriously decreases as the transparent material is chilled from below.  Fit your data with solutions to the heat equation to the determine the thermal diffusivity and thermo-optic coefficient of the material.
