THE POT-IN-POT REFRIGERATOR

THE POT-IN-POT REFRIGERATOR

• The pot-in-pot refrigerator, also known as Zeer in Arabic, is a way of keeping cool without electricity by using evaporative cooling.

• It is constructed by placing a clay pot withing a larger clay pot with wet sand in between and a wet cloth on top.

• As the water evaporates, there is a drop in temperature. The food stored in the inner container cools so it can be kept fresh for much longer in a hot, dry climate.

• Mohammed Bah Abba invented the device in 1995 and was awarded a Rolex Laureate (Rolex Awards for Enterprise) in 2000 for this ingenious technique.

CHINDOGU INVENTIONS

What is a chindogu? "Dogu" is the Japanese word for tool and "chin" might be best

translated as "really weird." Basically, it’s a tool that doesn't quite improve

our lives but it’s fun to look at because it's really weird. It’s just a fanciful invention of

questionable utility. Let’s see some examples. Try to describe

them and guess what they might be used for.
