= Tyndall's bar breaker
{wiki=Tyndall's_bar_breaker}
Tyndall's bar breaker, also known as Tyndall's bar experiment, is a demonstration of the scattering of light, typically used to illustrate the principles of light scattering and the Tyndall effect. Named after the Irish scientist John Tyndall, it illustrates how light interacts with small particles suspended in a medium (such as a colloid). In the experiment, a beam of light is directed through a liquid containing suspended particles.
