Abstract
Fuchs found phenomena that when high voltage is applied to deionized water filled in two contacted beakers, a floating water bridge forms spontaneously. In this paper, we examined flow direction of water bridge and what effects the addition of electrolytes such as NaCl, NaOH, and NH4Cl to the floating water bridge would give. We found that ionization degree reduced the length of water bridge though insoluble electrolyte Al2O3 had no effect on the length of water bridge.
Highlights
A lot of experiments on water have been reported since the ancient time
They were filled with water and a small quantity of water soluble electrolyte (NaCl, NaOH and NH4Cl) or insoluble electrolyte (Al2O3)
An experimental study on reduction of length of water bridge caused by added electrolytes was carried out
Summary
A lot of experiments on water have been reported since the ancient time. Water is a familiar substance and has many interested features. Floating water bridge seems to be caused with it. It can be reproduced if you have a high voltage electric generator and deionized water. First the top of two beakers filled with deionized water was in contact with each other, and they were setting apart gradually under high voltage. Spanning a bridge of water could be observed between top of two beakers. This experiment was reported by Fuchs [1,2,3]. We believe that the phenomenon was caused by electrical dipole moment of H2O molecular. We would like to know the flow and the effects of adding electrolytes to deionized water on the length of water bridge
