A&B Smoke is two separate liquids that when placed next to each other generate a light smoke vapor. It is imperative to remember that it is the mixing of fumes (or vapor) that generates the smoke. A stream of air enhances the effect. A&B Smoke is especially useful for steam effects in food shots. Do not use where people can breath the fumes. Wear gloves & eye protection when working with these chemicals. Hazardous Shipping & Handling Charges may apply.
