Physics Girl shows a vortex phenomenon (a falaco soliton) that can be reproduced in a pool on a sunny day. Two vortices are created with plates and made visible with food coloring.
Why Hacker News points people here: Cited as a concrete demonstration of vortex linkage, and as a better source link than the original submission.

Used as analogy for vortex linkage versus wormholes.

Indefinite causal order (indefinite causal structure) is already demonstrated at the quantum level at least. Do time crystals demonstrate macrostate retrocausality? There are time crystal in childrens' chemistry sets and they've been there for years. In this video [1], Physics Girl creates two vortices in a pool with plates and dyes the fluid flow between them with food coloring. How is this matter information flow between low pressure centers of local fluid vortices different from wormholes and ER=EPR particle state linkage? Is this effect of linkage between vortices the same thing as ER=EPR wormholes? Similarities: Low pressure in the center of a vortex; fluid vortical dynamics, State linkage across spacetime, Refractory occlusion, Glowing edge at the boundary of the system FWIU, there are various types of quantum entropy; entanglement and non-entanglement entropy. Quantum discord [2]: > In quantum information theory, quantum discord is a measure of nonclassical correlations between two subsystems of a quantum system. It includes correlations that are due to quantum physical effects but do not necessarily involve quantum entanglement. With wormholes, doesn't the degree of complexity of the universe increase significantly; when any particle state in a system with fluidic dynamics can be linked to any other particle state in spacetime, what is the degree of the Hilbert space? Can there be ER=EPR wormholes between here and the other side of the apparently expanding universe, a
