I no what methods i usualy use. But i figure ill bring up a method im thinking about trying and open it up to how other people distribute and move fog around the stage. The stock methods we deliver fog around the stage is with metal ducting like people use for their dryers. You can connect this to a chiller, or because or the material you can simply stick dry ice in the line as long as its not accessable and thus wont cause injury. we recently tried an effect where we put a tube up on a batton and chilled the fog that went through it so that fog poured down from above. The method i want to try is to use the same setup those sprinkler systems use. The systems im refering to are those that go into the ground so they are flush with the ground and you can walk on them and when the water is turned on a head pops out a little out of the ground and around the circular head there are a number of holes that water comes out of. I believe that what triggers the head to raise is the water pressure so the system would have to be altered slightly so that somthing else rose the head, but this would allow for fog to come from any platform easily and safely. also this has a built in method to make the distribution equal. thoughts?
