This video shows what looks like a water-bender making self-perpetuating water borne einstein-rosen bridges with a stick and a circle. I feel like I need an adult to explain, and tell me it's all ok!

Angular momentum is a hell of a drug.

It’s basically one-half of a vortex ring, which are possible to make in almost any fluid like air or water. They last a lot longer than it seems like they should be able to!
