    Break off both ends of the smoke tube and attach a rubber squeeze bulb to one end of the tube. When the bulb is squeezed, a chemical reaction produces white smoke. This smoke makes the air flow (in ventilation systems/ducts, etc.) visible. A single tube can be repeatedly used for about 50 tests.
