Here the first few days of October, I am in New York visiting my fiance’s family, her Dad tells me he is unsatisfied with how well his smoke machine works for his front yard Halloween display. Specifically, he wanted to the smoke to act more like fog and hug the ground. The way you do this is by chilling the fog so it stays low, dense, and heavy. There a few places online where you can find directions on various ways to accomplish this, but me, my brother and brother-in-law made a fog chiller (more than one, truth be told) years ago during the Psycho Detail days.
I told him I knew a plan for a low tech chiller using flexible drier tubing and a big trash can, simple to make, easy to clean, and comfortable. Off we went to Home Depot, and a little while later I got to create my first Halloween effect since the various parts of Psycho Detail scattered across the country a few years ago.
