Ice Box of the Future (1930)

The September 10, 1930 Syracuse Herald (Syracuse, NY) ran a piece about scientists' predictions for the future. A prediction is much more interesting when antiquated terms for modern conveniences are used. Case in point: the "ice box."

Another group of chemical scientists explain how the ice box of the future will tell the housewife if meat she buys is fresh or old. This age-finder is an atmosphere exhaled by the refrigerant dry ice or solid carbon dioxide. If the meat is fresh it retains its red color. If old, it turns brown.
