From the Man Cave.
Build yourself a smoke/steam generator.

Please note of updates to this article:
Parts and complete fog units are only available to club members only
There are no hot components used in this system as it is a water based device that works with an ultrasonic mist generator.
On the left is a picture of the prototype working.
Below is what you will need to build one.
Also required is a length of plastic pipe (I found plastic water pipe ideal) to make the funnel.
What you need to do.
To make the water tank you will need to cut 3 holes in the top of the plastic box. The first hole is 14mm for the bung on the ultrasonic generator, the second is 25mm for the fan and the third is 15mm for the funnel. See the picture below for the positioning of the holes.
