That?s a rippah!
One thing about any smoke/mist/haze effect, they can be catorgrised as having a mind of it?s own!
Register the design as you never know you might find the Medusa being commercially produced, with a ?Made in China? stamped on, as a smoke machine attachment!
This delivery is superior to the ones the ones I have had a hand in & it has got the added feature of adjustable location control.
It is a far cry from the smoke delivery Machines that we played with in the 60?s. Which had the added attraction of being a flame thrower &/or ballistic missile at times. As paraffin fluid was used for the heat cracked oil effect.  
I have gaff?d up a lot, using the plastic expandable elephant hose, with an inline fan, to assist the effect flow on long lengths. But normally this for dry ice, which docent have the sustained pressure capabilities of the haze/Smoke MacHines.
But think about registering, as I have had a couple of things. I developed turn up later as a commercial benefit to others, because I never bothered or was too slack to register the design.

Originally posted by Shatcher  my big dry ice fogger, I call him R2-D2. Made hin from a 55 gal drum and some water heating coils and dryer hose.  go for a patent.

 I think most of us have created weird & at times not so wonderful dry ice foggers. But I like your naming of the MacHines as Madusa & R2D2. Which is much nicer than the names I have called some of the DIY ones, that I have made up from modified metal rubbish bins, drums  & even the old tea urn.
The Madusa I doubt could carry a Paten. But as a Registered Design, which is cheap to do, can afford some protection on the design idea at least!

That's extremely impressive! :D

This device of yours has caused me a dilemma.  (First off, fantastic job it looks great)  Now my director has seen it and wants something like it for us.  Not only do I have to create Victorian London in a 42x20 space, but now the chimneys have to blow smoke. Stop giving him ideas. 

I'm just having fun.  Your device and sharing how to make it work should help us present a really impressive display for our patrons. 

Nope, no problem with the hoses melting, but the intake is a fairly heavy-duty rubber hose.  And the hose doesn't actually touch the nozzle, it's about a quarter-inch away from it.  It's possible, though, that the nozzle on our machine doesn't get all that hot.  I will keep checking, though, and thanks for the word of warning.

All else fails, you might be able to bend/shape some copper pipe or tubing for the intake, if the hoses keep melting.

And please, if you think of it, send me a picture of your Medusa in action!
