The Tyndall Effect
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The Tyndall effect is light scattering by colloidal particles, large enough to interact with light where a solution's particles cannot.
Show
A flashlight beam is visible crossing a foggy room, as water droplets scatter it, while the same beam stays invisible through clear salt water.
Watch for
A colored solution's beam still stays invisible — its particles are too small to scatter light.
