Pot-in-pot evaporative vegetable cooler

Keep produce cool without electricity

An updated "zeer" pot cooler that needs no power. A gap between the inner pot and the outer honeycomb wall is filled with wet sand. As the water evaporates through the honeycomb it pulls heat out, keeping tomatoes, greens and fruit cooler on a hot, dry day.
