Even if you haven't seen one in 40 years, this magic copper wand can bring back instant memories of sitting around a kitchen table, dipping hard-boiled eggs into glass ice cream bowls filled with vinegar-scented colored dyes rehydrated from tiny tablets; and the eggs, slowly drying, standing upright in holes punched out of the cardboard kit box; and sometimes-smeary decals or crayon resist doodles. Someone out there designed and patented this simple, specialized, and magically unforgettable human tool.
