Hello!
I'm trying to make an experiment about why the sky has blue color (light scattering) for my next week, class presentation. I achieved this with one white led, and a glass with nano particles (of polystyrene+acetone in alcohol or CaCO3 in water). The white light passes though the glass, the particles scatter the light and the light from the other side appears yellowish, while the glass seems like grey-blue. Do have any idea to make a solution, with different elements to scatter more blue light, so the color of the glass get more vivid.
Cheers,
