a spring means reeds etc a skilled artisan within the art will be able to enable a spring means trap door means or other means of shutting down air flow from expansion chamber 102 therefore the specific details shall not be detailed herein in order to attach the one way venturi 103 to expansion chamber via orifice 110 both orifice 110 and one way venturi 103 may be complimentarily threaded and sized to fit each other however it is not specifically required that the mode of attachment is via threading other modes of attachment such as gluing soldering etc are equally expedient for the task and will be readily understood by one skilled in the art chamber 102 is a sealed container and may embody many different shapes and sizes fig2 illustrates that chamber 102 comprises both the expansion chamber 110 and the flash freeze chamber 111 the expansion chamber 110 in this specification shall mean the region of the chamber 102 below the ice tray 109 the region above ice tray 109 is the flash freeze chamber 111 the main purpose of the expansion chamber 110 is to provide the natural engine for pushing out the smoke since the present invention does not use fans or other exhaust means in order to inject smoke out of cfgnsfds 100 the expansion chamber 110 must accomplish this function expansion chamber 110 works by closing inlet to allow pressure to build up naturally within expansion chamber 110 thereby forcing smoke and fog out of exhaust duct 108 the main function of flash freeze chamber 111 is to cool the smoke the cooling of the smoke accomplishes two main objectives first a cold smoke is more apt to lie low over the ground which is desirable in the entertainment industry second a.
