Unicef Sweden have developed a machine that turns sweat into drinking water
. They are asking participants in the Gothia Cup
to hand in their sweaty clothes to produce water and are hoping they will "drink some sweat to support clean drinking water. The expectation is to gather sweat from more than 70 different nations".
The goal is to raise awareness about the lack of clean water in the world, with the main purpose of raising money for water purification tablets for children. 780 million people still lack access to clean drinking water. [more inside]
