Electrochemical Polishing of Silverware: A Demonstration of Voltaic and Galvanic Cells Michelle M. Ivey and Eugene T. Smith
Using a battery and a graphite electrode, an electrolytic cell is constructed to generate a layer of tarnish on silverware. Students then determine that the tarnish can be removed by electrochemically converting it back to silver using aluminum foil and baking soda.

Microscale Transformations of Some Lead Compounds. A Cycle for Lead Minimizing the Production of Wastes Francisco J. Arnáiz and María R. Pedrosa
This set of basic experiments emphasizes that toxic products can be conveniently studied by using a combination of microscale techniques and simple schemes to recycle wastes. Here we propose a basic cycle for lead involving the consecutive transformation of lead(II) acetate to lead(II) formate, lead powder, and lead(II) oxide, with special emphasis on minimizing the production of wastes.

Ammonia Can Crush Ed Vitz
When a 12-oz aluminum soft drink can filled with ammonia or hydrogen chloride gas is inverted and dipped into water, the rapidly dissolving gas evacuates the can and the can is crushed before water can be drawn into it. This demonstrates, among other things, the remarkable strength of hydrogen bonds.

Microscale Thermite Reactions Francisco J. Arnáiz, Rafael Aguado, and Susana Arnáiz
The reaction of aluminum with the oxides of a variety of elements illustrates exothermic reactions that require a high activation energy. It is also an appropriate experiment with regard to the discussion of Ellingham diagrams. When drama is not the main objective, conducting these reactions at microscale level offers numerous advantages over the usual scale.
