Bet You’ve Never Seen A Complete Rainbow Circle (VIDEO)

Double rainbows are pretty cool and triple rainbows are really rare but have you ever seen a rainbow circle? Earthsky.org says "sky conditions have to be just right for this, and even if they are, the bottom part of a full-circle rainbow is usually blocked by your horizon. That’s why we see rainbows not as circles, but as arcs across our sky."

The video below from Niagara Falls proves that there is no pot of gold at the end of a rainbow.
