A method for an electric candle to realize visual effect of a dynamic flame, comprising the following steps: A. installing a removable upper cover on at least one cylindrical shell with only one open end and with a tubular holder fixed at a central part of the upper cover, the holder for holding a candle flame simulating object; vertically mounting a candle flame simulating object onto the holder by aid of a pivot so as to allow the candle flame simulating object to swing vertically; B. enabling the candle flame simulating object to pass through a central through hole of the upper cover, and extending a head part of the candle flame simulating object to outside of the upper cover; C. installing a Light Emitting Diode lamp on a vertical wall of the holder and located at the lower front of one lateral plane of the head part of the candle flame simulating object such that the light of the Light Emitting Diode lamp upwardly and obliquely emits onto said lateral plane of the head part of the candle flame simulating object by an elevation angle β; D. arranging a water stirring device at a lower part of the shell, and providing water into the shell to immerse a tail end of the candle flame simulating object; lighting up the LED lamp, and starting the water stirring device to allow a stream of water to shoot out from a water outlet of the water stirring device and to generate fluctuations on the water stored in the shell so as to enable the candle flame simulating object to swing back and forth and the light of the Light Emitting Diode lamp to be projected to the head part of the candle flame simulating object, resulting in the visual effect of a dynamic flame.
