Abstract:
To produce a controlled special effects cloud, an effects generation system comprising:a cryogenic fluid source, said cryogenic fluid source including a quantity of a cryogenic fluid and at least a fluid outlet, a pressurization assembly operatively associated with said cryogenic fluid source and structured to selectively maintain an outflow of said cryogenic fluid, under pressure, through said fluid outlet, a delivery assembly operatively connected with said fluid outlet of said cryogenic fluid source and structured to deliver said cryogenic fluid into a desired area, a quantity of a reactive fluid disposed in reactive proximity with said cryogenic fluid being delivered into the desired area, said delivered cryogenic fluid structured to at least partially cause a phase change of said reactive fluid sufficient to result in the formation of the special effects cloud at least partially by said reactive fluid, said delivery assembly includes a plurality of delivery ports, and said pressurization assembly is structured to maintain a substantially continuous outflow of said cryogenic fluid so as to substantially equalize a fluid flow pressure at each of said delivery ports of said delivery assembly.
