DIffusing LED with water and chemicals? Answered
I've been thinking about the best way to diffuse LED lighting over a large space, something like a wall. Standard way of doing it would be to lightly sandpaper acrylic glass and backlight it, or edgelight.
I have been thinking about filling the space between two sheets of acrylic glass with water to diffuse the light but that would need some additives, so on to the question.
Q: Is there any chemical that one could mix with water to make the solution more diffuse/milky that helps the transmission of light in the fluid and also helps the diffusion?
Since a fluid being backlit would change in temperature there might be some cool things one could do with that, a light panel that changes visual properties over time?
