You can make a rainbow in your yard on a sunny day with just some water from a hose. You could probably do it inside too but the light coming from artificial light sources have a different value on a spectroscope than light from the sun, the light would be different. The prismatic pattern you see on the reflection of a cd will demonstrate this. Notice the different patterns and.colors you get under different light sources, LED vs fluorescent, etc. Its too bad you believe in junk science
I think it's time to fucking realize it's not redheads but blondes that have no soul
