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 to the floating water bridge would give. We found that ionization degree reduced the length of water bridge though insoluble electrolyte had no effect on the length of water bridge.
