Double rainbow ponder

I've been pondering this question. If it's a double rainbow, does it have like double the colors? Or is it supposed to be more spontaneous? Less of an arch, more of just a splat of paint floating in the atmosphere? Is it double the size? I've never actually seen a double rainbow. My mother saw a giant bird eating a demented apple, and told me to come see, and I was so excited, because my hopes were up for some other colors in the sky besides blue. "Yay," I would say sarcastically like the opening theme of Mr. Sunshine. Yay... If the ocean was dried up 1 day, would there be no rainbows? That certainly would be hell wouldn't it? Maybe the sky is just some parallel universe. It's a mirror pointing at the vast ocean? If a dolphin swims by, I certainly see color behind it. So maybe if like 50 dolphins swam at the exact same spot... THAT'S HOW RAINBOWS ARE BORN... Then 2 groups of 50 dolphins... DOUBLE RAINBOW!
