Clay Pot Refrigeration

I saw this on YouTube: make a clay pot refrigeration container, called a Zeer Pot,  with sand and water.  It’s a very simple and effective technique that once constructed is good forever with the addition of water.

As well here’s a great case study on how this is helping people in Sudan, along with a technical manual and brief.  They use a clay lid instead of a damp towel, which makes more sense for long term usage.
