Mathematics at the Technical University of Denmark chose a "sweet" occupation. They poured honey from one vessel to another and tried to understand why a trickle of honey are stable and do not break up into droplets, such as, for example, water.

Sergey Senchenko and Tomas Bohr published his findings in the online journal Physics arXiv. It was found that the jet of honey is much more resistant than expected wound.

The water jet breaks up into droplets under the action of gravity and surface tension forces, but thicker liquid types honey or syrup behave differently. Mathematicians have long struggled hard to understand exactly what forces are doing a stable stream of honey.

The researchers developed a mathematical model in which honey is squeezed out of the hole and the trickle of falling endlessly with infinite height. The scientists then tried to figure out what it is that will cause a trickle break into droplets.

A trickle of honey staged various tests. It's pretty intense shaking from side to side. However, it seems that no matter how wide was the stream of honey, it still was uneasy. To break up a stream of drops of honey on the scientists had to apply just the same violent means.

Australian Yvonne Stokes, mathematician and expert on honey (it turns out, there are such), said that the phenomenon of jets honey is an old riddle that mathematicians have so far failed to resolve.

"It created a lot of models that predict when and under what conditions, the stream of thick liquid will break up into droplets, however, they were all non-working" — says Stokes.
