14 DAY TRIAL // Sweat isn't exactly poisonous if it somehow drops off your forehead and ends up in your mouth, but it does contain lots of substances the body knows have to be expelled, so consuming them again is a no go.
Sweat also tends to be really salty, another problem when it comes to its potability, or lack thereof.
A team of engineers led by designer Andreas Hammar have decided to make sweat drinkable though.
So they partnered up with the UNICEF and Swedish advertising agency Deportivo to make it happen. Discovery News had a field day checking it out.
The result? That weird, huge machine in the video I have embedded above this blog post.
Based on NASA technology that turns astronauts' sweat and urine into drinking water, the contraption is a drying machine that uses filters to purify any liquids placed in.
And I do mean placed, not poured. Sweaty clothes are put in and spun and squeezed until almost no perspiration is left. Then the accumulated liquid is processed.
The idea could greatly improve the lives of people living in arid areas, like some deserts in Africa and Asia.
