Somewhere Over the Rainbow
There is light
That's refract- and reflected
Truly an awesome sight

The purple strip is on the bottom
And the blue and green stripe right above it
Then yellow, just like lemon drops,
And orange and red upon the top
That's how we love it!

Somewhere Over the Rainbow
There's UV
Until ozone absorbs it
But only B and C.
