Scientists from the University of Chicago conducted an experiment in which they succeeded in the laboratory to create a three-lobe node from the vortex of water.
Also, scientists have been able to observe its evolution and decay.
To create a water vortex propeller physicists needed a special form created using the 3D printer. Watch the movement of water caused by this propeller, physicists helped small air bubbles that follow the movement of the water.
The situation brightened laser bubble 76,000 times per second tracked device, resembling computer tomograph.
During the experiment, 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.
