Air rings collide underwater. (Source)
How does this even happen? Like are these cause naturally or did a human/manmade thing cause this?
Dolphins can make them, I learned to do it, it’s a lot of fun. Just a way of pursing your lips when you blow bubbles
Life is amazing
toroidal vortexes!! they’re basically a tube rolling, but the tube is a circle. The rotation direction is inward or outward, instead of clockwise or counterclockwise like a “normal” vortex! You can make them by creating a cylindrical current of faster moving fluid around a similar current of slower moving fluid, aka pursing your lips when you blow bubbles!
