A rainbow appears when light from the sun interacts with moisture inside of the earth's atmosphere. It can be any type of moisture, even the water that shoots out of a whale's blowhole.

Yes, if everything aligns correctly a whale can fire rainbows into the air. If you don't believe us, watch this video.

This optical event took place during a whale watching cruise in Nova Scotia. Some have described it as the real-life equivalent of the Nyan Cat, the half-feline, half-Pop Tart meme who goes around shooting rainbows out of its behind.

If that's the case, rainbow whale needs a snappy new name. Success Whale, maybe? No matter what, the color-spewing marine mammal should be kept away from the Double Rainbow Guy. It would surely prove too much for him to handle.
