Probably a complex process in order to diffuse the refractive properties of water into all of the necessary colors. You can see in the past two episodes that flowing, unprocessed rainbows eventually turn back into normal water.
So liquid rainbows are light-suspension water derivatives. Wonder why the OH ions are so spicy though.
I don't remember the details about making rainbows, but it has to do with splitting light in to color light and mixing it with water... don't ask me again.
@David: I didn't notice you gave me hugs.
Yeah, Andromeda is heading for you. You got over 9000 years until it collides.
Re: discussion of Magic a while back.
I think the element of Magic is mostly tied to faith in one's friends, or a desire to be connected with people. Twilight discovered the sixth element when she realized how happy she was to see the other five there with her, and she lost her colors when she lost her faith in her friends ("With friends like you, who needs...
enemies...?")
If the other Elements are virtues that help form lasting and healthy relationships, the sixth element is both the desire to do so, and faith in those bonds.
Which is one reason why I like to imagine that Luna had, and lost, the sixth element, whether or not she knew she once had it. (wasn't it something of an enigma even then?)
I have a message from another time...
Yeah, working at the Rainbow Factory is horrific.......ly boring.
What about the pizza parties and singing?
Life is simple: it has no nontrivial normal subgroups.
All this talk of how rainbows are made is going right over my head!
Insert something witty that makes me better than all of you, here.
Pinkie's tastebugs are broken anyway.

Are those like tiny bugs in her mouth that taste things for her? Because that's super gross.
-Hugs David back-
Oh hi Enlong.
Yeah, Andromeda is heading for you. You got over 9000 years until it collides.
Maybe they're surveillance bugs that Pinkie uses to find out what others are tasting.
Wait, why does Pinkie have bugs? I feel like I missed something, here.

You look like a cadet.
I have a message from another time...
@Enlong: Sure, we'll go with that.
Yeah, Andromeda is heading for you. You got over 9000 years until it collides.
No, that's reserved for the poor bastard that has to scrub the latrines. With a toothbrush. That has their name on it.
There's no need to sharpen my pencils anymore. My pencils are sharp enough.
Even the dull ones will leave a mark.
@David: Sleep? Please, I have to put up with night flying in a few minutes.
Yeah, Andromeda is heading for you. You got over 9000 years until it collides.
So does Orion have to hold the toothbrush in his mouth while he scrubs latrines? That sounds pretty unsanitary. You have my sympathies, Orion.
Ponies obviously have stronger immune systems, or dirt forcefields or soemthing, given how much they do with the hooves and mouthes.

Mouthwash must be big in Equestria.
Oh sweet Celestia no! The worst we get is mess hall clean up.
