Water Droplets And Black Holes

Researchers at the University of Nottingham have published a paper where they use water droplets to simulate the dynamics of black holes. By using magnetic fields and electrodes they managed to spin levitating water droplets, and this produced some interresting results. As the droplet was spun at different velocities, the shape changed to form, among others, triangles,  squares and pentagons. This was due to the surface tension of the water droplet, and the scientists say this is very much like what happens at the event horizon of a black hole. The droplet experiment could hence be used to model such systems, a valuable tool in learning more about the dynamics of black holes. 

There is a video of the dropet spinning here. 

You spin me right round, baby.
