It is believed the rare phenomenon was recorded on November 13, 2021. Mammatus are sagging, pouch-like lumps on the undersides of clouds that usually happens after thunderstorms.

Composed primarily of ice, these cloud pouches can extend hundreds of miles in any direction, remaining visible in your sky for perhaps 10 or 15 minutes at a time.

The clip was uploaded on YouTube with a caption that read, "Late Saturday afternoon the sky was covered with these unusual clouds that made us feel as if we were trapped in a vivarium, then came the strong storm with lightning, winds, and hail. We were lucky to have been there to capture this strange phenomenon, which may be a product of weather manipulation."

So the question arises, how do these cloud bottoms appear like bubbles?
