An artificial fog generator device is provided with air jet pipes, an oil bath, filtering screens, and an enclosing housing to include all of these elements, and outlet channels for directing the generated cloud of oil bubbles from the housing, and an air compressor that feeds high pressure air into the spraying pipes. A much more efficient generator of fine oil bubbles is achieved by locating the air jet pipes directly above the surface of the oil bath. The compressed air is fed into the pipes that are located directly above the oil bath and high pressure air jets spraying into the oil bath cause a cloud of fine oil bubbles to fly out of the oil bath. The generated oil bubbles than pass through the filtering screens and are then directed out of the housing through the outlet channels. The fog or smoke generator housing may be portable, and have a carrying handle, and may contain the air compressor, and a power supply and battery to power the air compressor.
