ABSTRACT:
An accessory for a vapor generator, such as a smoke or fog machine, includes an elongated member that connects to an output nozzle of the vapor generator. The elongated member has one or more perforations formed in its sidewall along its length. A vapor generated by the vapor generator travels through an interior of the elongated member and escapes through the perforations to the ambient atmosphere. The effect creates a curtain of smoke or fog.
