A demonstration of small-angle scattering of light by a hair.
Laser pointers are used as they are essentially sources of radiation which are collimated. The oscillations that appear are the intensity of the Fourier transform of the sample shape, in this case an "infinite" cylinder.

These observations are used to calculate the diameter of the hairs in part II of this video. Part II is available here: http://www.youtube.com/watch?v=UZMOCE...
