@harry#2372 Stop or you're banned the very next time-

I just made a rainbow indoors without glass.

Don't believe you

What light source?

just a sec, I'll upload a pic. in my office, indoor lighting.

no sun

Was there a mirror present?

I used a CD.

oooo

A CD creates a prism effect

yes

That's not how you're supposed to do it.

no glass though

cd foil is like cheating

and standard lighting

That is definitely cheating

how is it cheating?

how is that cheating

It creates a prism effect that would not be present otherwise

OH because it works

Duh

refraction of light is the goal.

Without artificial influence

Which you gave

the foil is not a uniform surface it has colorations by themanufacturing proces which is oily or rainbowish,

Which makes it a void experiment.

the foil cast a rainbow on my desk. This is the same process actual rainbows go though.

then i can use a colidascope

well, yes.

sure i guess

A CD can create a rainbow without water.

again it is a projection of the surface then

That's literally cheating

you don't NEED water to create a rainbow.

you need a material that refracts light.

was the goal to specifically use water?

Is that so? Then do it without a CD.

the rainbow should be the light in the medium being refracted, not due to the coloration of the medium

ivo, how is it being colorized?
