Cigarette Smoke Finds Leak in Inner Tube (Mar, 1940)
Cigarette Smoke Finds Leak in Inner Tube
A burning cigarette can guide you in locating a leak in an inner tube, in case it is not convenient to dip the tube into a tub of water. The cigarette is moved around the surface of the inflated tube, until the air jet from the leak deflects the rising smoke. Make sure, before using this method, that there are no strong air currents in the room where it is being done.â€”R. B.
