  A vertical connection of water is formed when a high voltage electrode is
dipped in and pulled out of a container of deionized water. We considered the
formation and dynamical characteristics of this vertical water bridge. For the
first time in this field, instabilities were observed in the bridge that led to
an oscillatory behaviour which we categorized them into three dynamical
regimes. some explanations were supplied on the physics behind these dynamics.
We report the formation of macroscopic droplets during our experiments, which
their dynamics revealed that they are electrically charged. In some cases the
droplets levitated in the air due to the equality of gravity and electrical
force (acting in the opposite direction). Our results shed light on the physics
behind this phenomenon and the horizontal water bridge, which explanations
regarding its underlying physics have led to controversial theories and
discussions before.
