Kauffman, George B.; And Others – Journal of College Science Teaching, 1986
The use of sodium acetate solution to show supersaturation is a favorite among lecture demonstrations. However, careful adjustment of the solute-to-water ratio must be made to attain the most spectacular effect--complete solidification of the solution. Procedures to accomplish this are provided and discussed. (JN)

Kauffman, George B. – Journal of College Science Teaching, 1997
Describes an outdoor scientific demonstration of metal reduction, a reaction known as the thermit process. Heat from an ignition mixture is required to initiate the reaction, which then becomes self-sustaining. The demonstration provides a dazzling introduction to such fundamental general chemistry topics as oxidation-reduction, metallurgy,…
