Black Hole is a colorful series of images created by Swiss photographer Fabian Oefner, which shows paint modeled by centripetal force. The setup is very simple: various shades of acrylic paint are dripped onto a metallic rod, which is connected to a drill. When switched on, the paint starts to move away from the rod, creating these amazing looking structures.
The motion of the paint happens in a blink of an eye, the images you see are taken only millisecond after the drill was turned on. To capture the moment, where the paint forms that distinctive shape, Fabian connected a sensor to the drill, which sends an impulse to the flashes. These specialized units are capable of creating flashes as short as a 1/40000 of a second, freezing the motion of the paint.
A short video below explains how the images were created.
