The smoke gun makes it easy to find leaks in your ventilation system. It is also very good for demonstrating air flows, for example when controlling that your kitchen fan works as it should. The smoke from the smoke gun is not hazardous and the smoke gun only dispenses smoke when the trigger is pulled. It is fueled with oil that is very easy to refill.
