Water can be knotted

physicist at the University of Chicago for the first time succeeded in creating in the laboratory "trilobes" node from the vortex of water and observe its evolution and decay.

To create a host of water scientists needed a special form of the propeller, which they were able to create using the 3D-printer. Watch the movement of water caused by this propeller, physicists helped to fine air bubbles. During the experiment, they followed the movements of the water. The situation brightened laser bubble 76,000 times per second tracked device, resembling computer tomograph.

As a result, scientists were able to see, as the image, move and break up assemblies formed fluid motion. Previously, the possibility of the existence of such sites has been proved in theory, but so far nobody has been able to get them in the laboratory.

Study sites of importance not only for the hydrodynamics, but also, for example, to study the sun. Recently, scientists have found that the transfer of energy from the sun to the surface of the crown may be mediated by special tornado woven into braids.
