Random Sand Fact
Can wet sand keep food cool without electricity?
In Nigeria, a simple cooling method using two clay pots has gained wide attention. Wet sand is packed between the pots. As water evaporates from the sand, it carries heat away and lowers the temperature inside.
The method can help fresh food last longer where access to refrigeration is limited.
