Cooling with clay and water
Evaporative cooling traditions are recorded across ancient China, Egypt, India, and Iran.
Evaporative cooling kit
Zeer Pot Building Kit
A low-energy food cooler built from terracotta, sand, water, and simple garden materials. Practical, tactile, and designed for learning from a cooling idea with very deep roots.
0W cooling
Evaporation does the work, no plug or battery required.
Hands-on science
Build the chamber, pack the sand, and watch the effect.
Garden-ready
Terracotta and natural fill materials feel at home outdoors.
Bill of materials
Everything you need to build the cooling experiment, ready to unwrap.
Open the box and you are moments away from building a real evaporative cooler: stack the pots, fit the lid, follow the guide, and watch simple physics turn terracotta into a low-energy chill chamber.
A quiet technology with a long memory
Older than the fridge, newly useful again.
Evaporative cooling has appeared for centuries in hot, dry places: air passing over water jars, damp cloth, porous clay, and shaded storage. The zeer pot carries that same principle into a compact food cooler.
Mohammed Bah Abba
The Nigerian teacher adapted the pot-in-pot idea for rural food preservation in the late 1990s.
Low-energy resilience
Practical Action has promoted zeer pots as local-material coolers for keeping produce fresh longer.
