Twenty 1-inch sample squares spanning ferrous and non-ferrous metals
sized for the longer reach when students wire across a bench between power supply
supplied dry so the user adds acid and charges it before running heavy-current electrolysis loads
showing that air resistance — not mass — accounts for differences in fall time under gravity
