In depth
Unlike true solutions where particles are too small to scatter light, colloids scatter light noticeably, making the path of the light beam clearly visible.
Examples in the real world
Sunlight beams becoming visible when passing through dusty forest air or fog, or blue light scattering in milk diluted in water.
