[NSRCA-discussion] Smoke

[Jr LESHER]

Craft stores and costume stores have Fog machines.  They are usually more prominate around Halloween.  They use a liquid solution that reacts with heat to create a dense, smoke like fog.   I bought one a few years back for a kids Halloween party.  I don't recall any sort of residue resulting from using it, but could smell the fog.  Sort of like a really faint diesel scent.  It did however, put out a nice big cloud of fog.  It could be regulated on the amount.  I don't believe there is any toxic properties to it, it is the same stuff used for special effects.

  Has anyone experience with smoke generators that might be used to observe cooling airflows around motors / engines? I've experience with smoke wands / sticks, but the ones I'm familiar with produce corrosive / toxic smoke (and often way too much). I've also looked at the smoke generators used by the scale RC steamboat folks, but they don't seem to generate enough smoke. (I can get about the same with a soldering gun and flux / oil.) I'd really like a controllable wand that generated a fairly small stream of dense smoke. Any ideas?
