Crazy pool vortex
Physics Girl
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.
Cited as a concrete demonstration of vortex linkage, and as a better source link than the original submission.
