"Over the Rainbow", also known as "Somewhere Over the Rainbow", is a ballad by Harold Arlen with lyrics by Yip Harburg. It was written for the 1939 film The Wizard of Oz, in which it was sung by actress Judy Garland in her starring role as Dorothy Gale.

The sky inside a primary rainbow is brighter than the sky outside of the bow. This is because each raindrop is a sphere and it scatters light over an entire circular disc in the sky. The radius of the disc depends on the wavelength of light, with red light being scattered over a larger angle than blue light.

You may already know that there is no “end” of a rainbow — science tells us that their arch shape is simply an illusion. In reality, while those of us on the ground can only see the light reflected by raindrops above the horizon, viewers in aircraft can sometimes see a rainbow's full, 360-degree circle.

Folklore depicts leprechauns as mistrustful creatures who detest humans. According to legend, leprechauns found the abandoned gold and buried it again so no human could ever find it. The old folktales tell us that there is a pot of gold hidden where the end of any rainbow touches the earth.
