How water moves
This image was obtained by putting a bit of Lycopodium on water thikened with glycerin and moving straight through it with a stick. The aim is to understand how water moves. It doesn't move like porridge. It moves in surfaces.
You can drop black ink into a cup of water and see how it moves. It doesn't dissolve evenly, but forms this mushroom shaped surfaces.
