I was initially quite impressed by this video, until I tried to replicate it. The water appears blue in their trial because the cell phone light they are using is pale blue.

[@jameslincoln8476]

That is a fair criticism, but the truth is, the sun it's self is Bluer than an incandescent flashlight, Most people will have cell phone flashlights at their immediate disposal, which is the goal of this movie. Note that we also demonstrated the sunset effect which proves there is plenty of yellow in our imitation sunlight. If you are having trouble performing the experiment, you were probably using too much milk, or have a flashlight that is not hot enough. The hotter, the bluer.

very precise

[@dimitar4y]

This is so simple and they don't even show it in schools... that hurts.

[@jameslincoln8476]

People don't know about these simple tricks, that's why we have to make these videos.

[@Fightcools]

This is in my homework

[@barbaravargas3972]

BRILLIANT
I like the indie rock song

[@BITTYBOY121]

Pretty cleaver ! I guess that explains why the sky's blue and why our blue, grey and light green eyes also scatter light in the same fashion ?

[@dimitar4y]

Few drops of milk? Damn.

[@biasesports9586]
