Somewhere over the rainbow, way up high. Nothing exists because a rainbow is just a refraction of light particles in the condensed mist that forms in the ionized atmosphere of an electrical storm, and you can't go above a rainbow because technically it exists everywhere. And someday I'll wish upon a star and nothing will happen because stars are simply balls of fire and nuclear explosions billions and billions of miles away and they are not conscious and they can't grant wishes because they are simply chemical reactions that we can create in a laboratory. And that's the truth. Rawr.
