Summary

The authors used a pair of spherical electrodes, facing each other in the test water so as to minimize unexpected high electrical density on the surface due to the existence of a singular point. It was found that supercooled water freezes in a few seconds after applying the electric charge. It was also found that the freezing is a statistical phenomenon. There are some tendencies, however, that the higher the value of direct-current voltage applied or showing that the closer the distance between two electrodes is, the easier the water freezes. The idea of a probability of freezing while a specific current flows for a time interval at a certain temperature was introduced. The probability of freezing was calculated under two different conditions and the results were compared in order to confirm the assumption. As a result, it was concluded that the probability depends only on the past record of current flow.
