Water and its secrets

Water for many people is a simple element of the earth, but it still has its secrets.
Researches are discovering more about this element, much research has been done to uncover the structure of water beyond the H2O scale, which is thought to be responsible for many of water’s unique properties. However, the nature of this structure, governed by hydrogen bonds, is currently unknown.

When exposed to a high-voltage electric field, water in two beakers climbs out of the beakers and crosses empty space to meet, forming the water bridge. The liquid bridge, hovering in space, appears to the human eye to defy gravity.

Upon investigating the phenomenon, the scientists found that water was being transported from one beaker to another, usually from the anode beaker to the cathode beaker. The cylindrical water bridge, with a diameter of 1-3 mm, could remain intact when the beakers were pulled apart at a distance of up to 25 mm.

Why water would act this way was a surprise, Fuchs told PhysOrg.com. But the group’s analyses have shown that the explanation may lie within the nature of the water’s structure. Initially, the bridge forms due to electrostatic charges on the surface of the water. The electric field then concentrates inside the water, arranging the water molecules to form a highly ordered microstructure. This microstructure remains stable, keeping the bridge intact.
