The Persistence of the Candle-and-Cylinder Misconception.
Birk, James P.; Lawson, Anton E.
Journal of Chemical Education, v76 n7 p914-16 Jul 1999
Argues that the candle-and-cylinder demonstration does not show that air is composed of 21% oxygen. Finds that the heating of air results in a partial expulsion of air, and that the flame is extinguished by a local, rather than a complete, consumption of oxygen. (WRM)
