Introduction: Make Smoke Without Heat Using Common Chemicals
This video demonstrates a simple chemical reaction between ammonia (NH3) and hydrochloric acid (HCl) to form the salt ammonium chloride (NH4Cl). When the reaction takes place between the two reactants as their vapors mix in the air the solid ammonium chloride product is formed in flowing trails ideal for beautiful smoke photography. One of the comments I have so far received on YouTube suggested it would be great for use with lasers! What a great idea! Maybe I'll make a followup video.

Is it toxic?

Hydrochloric acid and ammonia are somewhat hazardous and can be difficult to obtain. Model railroad enthusiasts use a heating element and oil to produce smoke. A design for a model smoke generator can be found here :http://www.scale4x4rc.org/forums/showthread.php?t=25024

Neat project, thanks for the link! I prefer glycerin over oil for that particular style of fogger.
