Rainbows are Circular

[Furryanimal]

Rainbows are full circles, not semicircles – it’s just that from the ground you can usually only see their upper half. From the air, as this video from skydiver Anthony Killeen shows, the full circle can be seen in all its glory. the Knowledge

The full circle rainbow is called a glory.

Love that! How exciting!
I once saw the bottom half of a rainbow in the sky and it looked like a giant smile!
I didn't know it was a normal thing. I thought it was only FOR ME! hahaha!
