The Slow Mo Guys squirted various colors of ink into a big tank of water and shot it on white seamless with a phantom 4K camera. The resulting footage, played back in suuuuuper slllllowwww moooootion, is utterly entrancing.

It doesn't take long for the ink to diffuse uniformly throughout the water. Filming it in slow motion allows us to witness the dense, dramatic stages of its early spread – like a dynamic version of this series by Italian photographer Alberto Seveso.

See FYFD for more on the physics of ink diffusing in water.
