Experiment 8: Properties and Composition of Air

The three QuickTime movies listed below show the incomplete combustion of filter paper in a closed container.  The movies are supplemental material to an article entitled Paradoxes, Puzzles, and Pitfalls of Incomplete Combustion Demonstrations by Ed Vitz that recently appeared in the Journal of Chemical Education (J. Chem. Educ. 2000, 77, 1011).

If you need QuickTime, it may be downloaded for free from Apple.
